Automatically control 52 the grade and slope of intermediate lanes by means of reference lines or a mat

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 22 1 referencing device and a slope control device. When the finish of the grade 2 prepared for paving is superior to the established tolerances and when, in the 3 opinion of the Engineer, further improvement to the line, grade, cross-section, 4 and smoothness can best be achieved without the use of the reference line, a 5 mat referencing device may be substituted for the reference line. Substitution of 6 the device will be subject to the continued approval of the Engineer. A joint 7 matcher may be used subject to the approval of the Engineer. The reference line 8 may be removed after completion of the first course of HMA when approved by 9 the Engineer. Whenever the Engineer determines that any of these methods are 10 failing to provide the necessary vertical control, the reference lines will be 11 reinstalled by the Contractor. 12 13 Furnish and install all pins, brackets, tensioning devices, wire, and accessories 14 necessary for satisfactory operation of the automatic control equipment. 15 16 If the paving machine in use is not providing the required finish, the Engineer 17 may suspend Work as allowed by Section 1-08.6. 18 19 5-04.3(3)D Material Transfer Device or Material Transfer Vehicle 20 Use a material transfer device (MTD) or material transfer vehicle (MTV) to 21 deliver the HMA from the hauling equipment to the paving machine for any lift in 22 (or partially in) the top 0.30 feet of the pavement section used in traffic lanes. 23 However, an MTD/V is not required for HMA placed in irregularly shaped and 24 minor areas such as tapers and turn lanes, or for HMA mixture that is accepted 25 by Visual Evaluation. At the Contractor’s request the Engineer may approve 26 paving without an MTD/V; the Engineer will determine if an equitable adjustment 27 in cost or time is due. If a windrow elevator is used, the Engineer may limit the 28 length of the windrow in urban areas or through intersections. 29 30 To be approved for use, an MTV: 31 32 1. Shall be a self-propelled vehicle, separate from the hauling vehicle or 33 paver. 34 35 2. Shall not connected to the hauling vehicle or paver. 36 37 3.

When 9 requested by the Engineer, provide a Type 1 Working Drawing of the 10 manufacturer’s recommendation for the use of any roller planned for use on the 11 project. Do not use rollers that crush aggregate, produce pickup or washboard, 12 unevenly compact the surface, displace the mix, or produce other undesirable 13 results. 14 15 5-04.3(4) Preparation of Existing Paved Surfaces 16 Before constructing HMA on an existing paved surface, the entire surface of the 17 pavement shall be clean. Entirely remove all fatty asphalt patches, grease drippings, 18 and other deleterious substances from the existing pavement to the satisfaction of 19 the Engineer. Thoroughly clean all pavements or bituminous surfaces of dust, soil, 20 pavement grindings, and other foreign matter. Thoroughly remove any cleaning or 21 solvent type liquids used to clean equipment spilled on the pavement before paving 22 proceeds. Fill all holes and small depressions with an appropriate class of HMA. 23 Level and thoroughly compact the surface of the patched area. 24 25 Apply a uniform coat of asphalt (tack coat) to all paved surfaces on which any course 26 of HMA is to be placed or abutted. Apply tack coat to cover the cleaned existing 27 pavement with a thin film of residual asphalt free of streaks and bare spots. Apply a 28 heavy application of tack coat to all joints. For Roadways open to traffic, limit the 29 application of tack coat to surfaces that will be paved during the same working shift. 30 Equip the spreading equipment with a thermometer to indicate the temperature of 31 the tack coat material. 32 33 Do not operate equipment on tacked surfaces until the tack has broken and cured. 34 Repair tack coat damaged by the Contractor’s operation, prior to placement of the 35 HMA. 36 37 Unless otherwise approved by the Engineer, use cationic emulsified asphalt CSS-1, 38 CSS-1h, STE-1, or Performance Graded (PG) asphalt for tack coat. The CSS-1 and 39 CSS-1h may be diluted with water at a rate not to exceed one part water to one part 40 emulsified asphalt. Do not allow the tack coat material to exceed the maximum 41 temperature recommended by the asphalt supplier. 42 43 When shown in the Plans, prelevel uneven or broken surfaces over which HMA is to 44 be placed by using an asphalt paver, a motor patrol grader, or by hand raking, as 45 approved by the Engineer. 46 47 5-04.3(4)A Crack Sealing 48 5-04.3(4)A1 General 49 When the Proposal includes a pay item for crack sealing, seal all cracks ¼ 50 inch in width and greater. 51

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 24 1 Cleaning: Ensure that cracks are thoroughly clean, dry and free of all loose 2 and foreign material when filling with crack sealant material. Use a hot 3 compressed air lance to dry and warm the pavement surfaces within the 4 crack immediately prior to filling a crack with the sealant material. Do not 5 overheat pavement. Do not use direct flame dryers. Routing cracks is not 6 required. 7 8 Sand Slurry: For cracks that are to be filled with sand slurry, thoroughly mix 9 the components and pour the mixture into the cracks until full. Add additional 10 CSS-1 cationic emulsified asphalt to the sand slurry as needed for 11 workability to ensure the mixture will completely fill the crack. Strike off the 12 sand slurry flush with the existing pavement surface and allow the mixture 13 to cure. Top off cracks that were not completely filled with additional sand 14 slurry. Do not place the HMA overlay until the slurry has fully cured. 15 16 Hot Poured Sealant: For cracks that are to be filled with hot poured 17 sealant, apply the material in accordance with these requirements and the 18 manufacturer's recommendations. Furnish a Type 1 Working Drawing of the 19 manufacturer's product information and recommendations to the Engineer 20 prior to the start of work, including the manufacturer’s recommended 21 heating time and temperatures, allowable storage time and temperatures 22 after initial heating, allowable reheating criteria, and application temperature 23 range. Confine hot poured sealant material within the crack. Clean any 24 overflow of sealant from the pavement surface. If, in the opinion of the 25 Engineer, the Contractor’s method of sealing the cracks with hot poured 26 sealant results in an excessive amount of material on the pavement surface, 27 stop and correct the operation to eliminate the excess material. 28 29 5-04.3(4)A2 Crack Sealing Areas Prior to Paving 30 In areas where HMA will be placed, use sand slurry to fill the cracks. 31 32 5-04.3(4)A3 Crack Sealing Areas Not to be Paved 33 In areas where HMA will not be placed, fill the cracks as follows: 34 35 1. Cracks ¼ inch to 1 inch in width - fill with hot poured sealant. 36 37 2. Cracks greater than 1 inch in width – fill with sand slurry. 38 39 5-04.3(4)B Soil Residual Herbicide 40 Where shown in the Plans, apply one application of an approved soil residual 41 herbicide. Comply with Section 8-02.3(3)B. Complete paving within 48 hours of 42 applying the herbicide. 43 44 Use herbicide registered with the Washington State Department of Agriculture 45 for use under pavement. Before use, obtain the Engineer’s approval of the 46 herbicide and the proposed rate of application. Include the following information 47 in the request for approval of the material: 48 49 1.

Proposed Rate of Application. 6 7 5-04.3(4)C Pavement Repair 8 Excavate pavement repair areas and backfill these with HMA in accordance with 9 the details shown in the Plans and as staked. Conduct the excavation 10 operations in a manner that will protect the pavement that is to remain. Repair 11 pavement not designated to be removed that is damaged as a result of the 12 Contractor’s operations to the satisfaction of the Engineer at no cost to the 13 Contracting Agency. Excavate only within one lane at a time unless approved 14 otherwise by the Engineer. Do not excavate more area than can be completely 15 backfilled and compacted during the same shift. 16 17 Unless otherwise shown in the Plans or determined by the Engineer, excavate 18 to a depth of 1.0 feet. The Engineer will make the final determination of the 19 excavation depth required. 20 21 The minimum width of any pavement repair area shall be 40 inches unless 22 shown otherwise in the Plans. Before any excavation, sawcut the perimeter of 23 the pavement area to be removed unless the pavement in the pavement repair 24 area is to be removed by a pavement grinder. 25 26 Excavated materials shall be the property of the Contractor and shall be 27 disposed of in a Contractor-provided site off the Right of Way or used in 28 accordance with Sections 2-02.3(3) or 9-03.21. 29 30 Apply a heavy application of tack coat to all surfaces of existing pavement in the 31 pavement repair area, in accordance with Section 5-04.3(4). 32 33 Place the HMA backfill in lifts not to exceed 0.35-foot compacted depth. 34 Thoroughly compact each lift by a mechanical tamper or a roller. 35 36 5-04.3(5) Producing/Stockpiling Aggregates, RAP, & RAS 37 Produce aggregate in compliance with Section 3-01. Comply with Section 3-02 38 for preparing stockpile sites, stockpiling, and removing from stockpile each of 39 the following: aggregates, RAP, and RAS. Provide sufficient storage space for 40 each size of aggregate, RAP and RAS. Fine aggregate or RAP may be uniformly 41 blended with the RAS as a method of preventing the agglomeration of RAS 42 particles. Remove the aggregates, RAP and RAS from stockpile(s) in a manner 43 that ensures minimal segregation when being moved to the HMA plant for 44 processing into the final mixture. Keep different aggregate sizes separated until 45 they have been delivered to the HMA plant. 46 47 5-04.3(5)A Stockpiling RAP or RAS for High RAP/Any RAS Mixes 48 Do not place any RAP or RAS into a stockpile which has been sequestered 49 for a High RAP/Any RAS mix design. Do not incorporate any RAP or RAS 50 into a High RAP/Any RAS mixture from any source other than the stockpile 51 which was sequestered for approval of that particular High RAP/Any RAS 52 mix design.

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 26 1 2 RAP that is used in a Low RAP/No RAS mix is not required to come from a 3 sequestered stockpile. 4 5 5-04.3(6) Mixing 6 The asphalt supplier shall introduce anti-stripping additive, in the amount 7 designated on the QPL for the mix design, into the asphalt binder prior to 8 shipment to the asphalt mixing plant. 9 10 Anti-strip is not required for temporary work that will be removed prior to Physical 11 Completion. 12 13 Use asphalt binder of the grade, and from the supplier, in the approved mix 14 design. 15 16 Prior to introducing reclaimed materials into the asphalt plant, remove wire, 17 nails, and other foreign material. Discontinue use of the reclaimed material if the 18 Engineer, in their sole discretion, determines the wire, nails, or other foreign 19 material to be excessive. 20 21 Size RAP and RAS prior to entering the mixer to provide uniform and thoroughly 22 mixed HMA. If there is evidence of the RAP or RAS not breaking down during 23 the heating and mixing of the HMA, immediately suspend the use of the RAP or 24 RAS until changes have been approved by the Engineer. 25 26 After the required amount of mineral materials, RAP, RAS, new asphalt binder 27 and recycling agent have been introduced into the mixer, mix the HMA until 28 complete and uniform coating of the particles and thorough distribution of the 29 asphalt binder throughout the mineral materials, RAP and RAS is ensured. 30 31 Upon discharge from the mixer, ensure that the temperature of the HMA does 32 not exceed the optimum mixing temperature shown on the approved Mix Design 33 Report by more than 25°F, or as approved by the Engineer. When a WMA 34 additive is included in the manufacture of HMA, do not heat the WMA additive 35 (at any stage of production including in binder storage tanks) to a temperature 36 higher than the maximum recommended by the manufacturer of the WMA 37 additive. 38 39 A maximum water content of 2 percent in the mix, at discharge, will be allowed 40 providing the water causes no problems with handling, stripping, or flushing. If 41 the water in the HMA causes any of these problems, reduce the moisture 42 content. 43 44 During the daily operation, HMA may be temporarily held in approved storage 45 facilities. Do not incorporate HMA into the Work that has been held for more than 46 24 hours after mixing. Provide an easily readable, low bin-level indicator on the 47 storage facility that indicates the amount of material in storage. Waste the HMA 48 in storage when the top level of HMA drops below the top of the cone of the 49 storage facility, except as the storage facility is being emptied at the end of the 50 working shift. Dispose of rejected or waste HMA at no expense to the 51 Contracting Agency. 52

The Contractor shall sample the HMA 3 mixture in the presence of the Engineer and in accordance with FOP 4 for WAQTC T 168. 5 6 5-04.3(9)B3 Mixture Statistical Evaluation – Acceptance Testing 7 Comply with Section 1-06.2(1). 8 9 The Contracting Agency will test the mixture sample from each sublot 10 (including sublots in a test section) for the properties shown in Table 11 11. 12 Table 11 Testing Required for each HMA Mixture Sublot Test Procedure Performed by Va WSDOT SOP Engineer 731 Asphalt Binder Content FOP for Engineer AASHTO T 308 Gradation: Percent Passing FOP for Engineer 1½″, 1″, ¾″, ½″, ⅜″, No. 4, WAQTC No. 8, No. 200 T 27/T 11 13 14 The mixture samples and tests taken for the purpose of determining 15 acceptance of the test section (as described in Section 5-04.3(9)A) 16 shall also be used as the test results for acceptance of the mixture 17 described in 5-04.3(9)B3, 5-04.3(9)B4, 5-04.3(9)B5, and 5-04.3(9)B6. 18 19 5-04.3(9)B4 Mixture Statistical Evaluation – Pay Factors 20 Comply with Section 1-06.2(2). 21 22 The Contracting Agency will determine a pay factor (PFi) for each of 23 the properties in Table 11, for each mixture lot, using the quality level 24 analysis in Section 1-06.2(2)D. For Gradation, a pay factor will be 25 calculated for each of the sieve sizes listed in Table 11 which is equal 26 to or smaller than the maximum allowable aggregate size (100 percent 27 passing sieve) of the HMA mixture. The USL and LSL shall be 28 calculated using the Job Mix Formula Tolerances (for Statistical 29 Evaluation) in Section 9-03.8(7). 30 31 If a constituent is not measured in accordance with these 32 Specifications, its individual pay factor will be considered 1.00 in 33 calculating the Composite Pay Factor (CPF). 34 35 5-04.3(9)B5 Mixture Statistical Evaluation – Composite Pay 36 Factors (CPF) 37 Comply with Section 1-06.2(2). 38 39 In accordance with Section 1-06.2(2)D4, the Contracting Agency will 40 determine a Composite Pay Factor (CPF) for each mixture lot from the 41 pay factors calculated in Section 5-04.3(9)B4, using the price

To 22 request a retest, submit a written request to the Contracting Agency 23 within 7 calendar days after the specific test results have been posted 24 to the website or emailed to the Contractor, whichever occurs first. The 25 Contracting Agency will send a split of the original acceptance sample 26 for testing by the Contracting Agency to either the Region Materials 27 Laboratory or the State Materials Laboratory as determined by the 28 Engineer. The Contracting Agency will not test the split of the sample 29 with the same equipment or by the same tester that ran the original 30 acceptance test. The sample will be tested for a complete gradation 31 analysis, asphalt binder content, and Va, and the results of the retest 32 will be used for the acceptance of the HMA mixture in place of the 33 original mixture sublot sample test results. The cost of testing will be 34 deducted from any monies due or that may come due the Contractor 35 under the Contract at the rate of $250 per sample. 36 37 5-04.3(9)C Vacant 38 39 5-04.3(9)D Mixture Acceptance – Visual Evaluation 40 Visual Evaluation of HMA mixture will be by visual inspection by the 41 Engineer or, in the sole discretion of the Engineer, the Engineer may sample 42 and test the mixture. 43

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 34 1 5-04.3(9)D1 Mixture Visual Evaluation – Lots, Sampling, Testing, 2 Price Adjustments 3 HMA mixture accepted by Visual Evaluation will not be broken into lots 4 unless the Engineer determines that testing is required. When that 5 occurs, the Engineer will identify the limits of the questionable HMA 6 mixture, and that questionable HMA mixture shall constitute a lot. Then, 7 the Contractor will take samples from the truck, or the Engineer will 8 take core samples from the roadway at a minimum of three random 9 locations from within the lot, selected in accordance with WSDOT Test 10 Method T 716, taken from the roadway in accordance with WSDOT 11 SOP 734, and tested in accordance with WSDOT SOP 737. The 12 Engineer will test one of the samples for all constituents in Section 5- 13 04.3(9)B3. If all constituents from that test fall within the Job Mix 14 Formula Tolerances (for Visual Evaluation) in Section 9-03.8(7), the lot 15 will be accepted at the unit Contract price with no further evaluation. 16 17 When one or more constituents fall outside those tolerance limits, the 18 other samples will be tested for all constituents in Section 5-04.3(9)B3, 19 and a Job Mix Compliance Price Adjustment will be calculated in 20 accordance with Table 13. 21 Table 13 Visual Evaluation – Out of Tolerance Procedures Comply with the Following Pay Factors1 Section 5-04.3(9)B4 Composite Pay Factors2 Section 5-04.3(9)B5 Price Adjustments Section 5-04.3(9)B6 1The Visual Evaluation tolerance limits in Section 9-03.8(7) will be used in the calculation of the PFi. 2The maximum CPF shall be 1.00. 22 23 5-04.3(9)E Mixture Acceptance – Notification of Acceptance Test 24 Results 25 The results of all mixture acceptance testing and the Composite Pay Factor 26 (CPF) of the lot after three sublots have been tested will be available to the 27 Contractor through The Contracting Agency’s website. 28 29 The Contracting Agency will endeavor to provide written notification (via 30 email to the Contractor’s designee) of acceptance test results through its 31 web-based materials testing system Statistical Analysis of Materials (SAM) 32 within 24 hours of the sample being made available to the Contracting 33 Agency. However, the Contractor agrees: 34 35 1. Quality control, defined as the system used by the Contractor to 36 monitor, assess, and adjust its production processes to ensure 37 that the final HMA mixture will meet the specified level of quality, 38 is the sole responsibility of the Contractor. 39 40 2. The Contractor has no right to rely on any testing performed by the 41 Contracting Agency, nor does the Contractor have any right to rely 42 on timely notification by the Contracting Agency of the Contracting 43 Agency’s test results (or statistical analysis thereof), for any part

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 35 1 of quality control and/or for making changes or correction to any 2 aspect of the HMA mixture. 3 4 3. The Contractor shall make no claim for untimely notification by the 5 Contracting Agency of the Contracting Agency’s test results or 6 statistical analysis. 7 8 5-04.3(10) HMA Compaction Acceptance 9 For all HMA, the Contractor shall comply with the General Compaction 10 Requirements in Section 5-04.3(10)A. The Contracting Agency will evaluate all 11 HMA for compaction compliance with one of the following - Statistical Evaluation, 12 Visual Evaluation, or Test Point Evaluation - determined by the criteria in Table 13 14: 14 Table 14 Criteria for Determining Method of Evaluation for HMA Compaction1 Test Point Statistical Evaluation Visual Evaluation of Evaluation of HMA of HMA Compaction is HMA Compaction is Compaction is Required For: Required For: Required For: • Any HMA for which • “HMA for • Any HMA not the specified course Preleveling…” meeting the thickness is greater • “HMA for criteria for than 0.10 feet, and Pavement Statistical the HMA is in: Repair…” Evaluation or o traffic lanes, Visual Evaluation including but not limited to: • ramp lanes • truck climbing lanes • weaving lanes • speed change lanes 1This table applies to all HMA, and shall be the sole basis for determining the acceptance method for compaction. 15 16 The Contracting Agency may, at its sole discretion, evaluate any HMA for 17 compliance with the Cyclic Density requirements of Section 5-04.3(10)B. 18 19 5-04.3(10)A HMA Compaction – General Compaction Requirements 20 Immediately after the HMA has been spread and struck off, and after 21 surface irregularities have been adjusted, thoroughly and uniformly 22 compact the mix. The completed course shall be free from ridges, ruts, 23 humps, depressions, objectionable marks, and irregularities and shall 24 conform to the line, grade, and cross-section shown in the Plans. If 25 necessary, alter the JMF in accordance with Section 9-03.8(7) to achieve 26 desired results. 27

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 36 1 Compact the mix when it is in the proper condition so that no undue 2 displacement, cracking, or shoving occurs. Compact areas inaccessible to 3 large compaction equipment by mechanical or hand tampers. Remove HMA 4 that becomes loose, broken, contaminated, shows an excess or deficiency 5 of asphalt, or is in any way defective. Replace the removed material with 6 new HMA, and compact it immediately to conform to the surrounding area. 7 8 The type of rollers to be used and their relative position in the compaction 9 sequence shall generally be the Contractor’s option, provided the specified 10 densities are attained. An exception shall be that pneumatic tired rollers 11 shall be used for compaction of the wearing course beginning October 1st 12 of any year through March 31st of the following year. Coverage with a steel 13 wheel roller may precede pneumatic tired rolling. Unless otherwise 14 approved by the Engineer, operate rollers in the static mode when the 15 internal temperature of the mix is less than 175°F. Regardless of mix 16 temperature, do not operate a roller in a mode that results in checking or 17 cracking of the mat. 18 19 On bridge decks and on the five feet of roadway approach immediately 20 adjacent to the end of bridge/back of pavement seat, operate rollers in static 21 mode only. 22 23 5-04.3(10)B HMA Compaction – Cyclic Density 24 Low cyclic density areas are defined as spots or streaks in the pavement 25 that are less than 90 percent of the theoretical maximum density. At the 26 Engineer’s discretion, the Engineer may evaluate the HMA pavement for 27 low cyclic density, and when doing so will follow WSDOT SOP 733. A $500 28 Cyclic Density Price Adjustment will be assessed for any 500-foot section 29 with two or more density readings below 90 percent of the theoretical 30 maximum density. 31 32 5-04.3(10)C HMA Compaction Acceptance – Statistical Evaluation 33 HMA compaction which is accepted by Statistical Evaluation will be based 34 on acceptance testing performed by the Contracting Agency, and statistical 35 analysis of those acceptance tests results. This will result in a Compaction 36 Price Adjustment. 37 38 5-04.3(10)C1 HMA Compaction Statistical Evaluation – Lots and 39 Sublots 40 HMA compaction which is accepted by Statistical Evaluation will be 41 evaluated by the Contracting Agency dividing the project into 42 compaction lots, and each compaction lot will be evaluated using 43 stratified random sampling by the Contracting Agency sub-dividing 44 each compaction lot into compaction sublots. All mixture in any 45 individual compaction lot shall be of the same mix design. The 46 compaction sublots will be numbered in the order in which the mixture 47 (of a particular mix design) is paved. 48 49 Each compaction lot comprises a maximum of 15 compaction sublots, 50 except for the final compaction lot of each mix design on the Contract, 51 which comprises a maximum of 25 sublots. 52

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 37 1 Each compaction sublot shall be uniform in size as shown in Table 15, 2 except that the last compaction sublot of each day may be increased 3 to a maximum of two times the compaction sublot quantity calculated. 4 Minor variations in the size of any sublot shall not be cause to invalidate 5 the associated test result. 6 Table 15 HMA Compaction Sublot Size HMA Original Plan Quantity Compaction Sublot Size (tons)1 (tons) <20,000 100 20,000 to 30,000 150 >30,000 200 1 In determining the plan quantity tonnage, do not include any tons accepted by test point evaluation. 7 8 The following will cause one compaction lot to end prematurely and a 9 new compaction lot to begin: 10 11 • For a compaction lot in progress with a compaction CPF less 12 than 0.75, a new compaction lot will begin at the Contractor’s 13 request after the Engineer is satisfied that material 14 conforming to the Specifications can be produced. See also 15 Section 5-04.3(11)F. 16 17 All HMA which is paved on a bridge and accepted for compaction by 18 Statistical Evaluation will compose a bridge compaction lot. If the 19 contract includes such HMA on more than one bridge, compaction will 20 be evaluated on each bridge individually, as separate bridge 21 compaction lots. 22 23 Bridge compaction sublots will be determined by the Engineer subject 24 to the following: 25 26 • All sublots on a given bridge will be approximately the same 27 size. 28 29 • Sublots will be stratified from the lot. 30 31 • In no case will there be less than 3 sublots in each bridge 32 compaction lot. 33 34 • No sublot will exceed 50 tons. 35 36 • Compaction test locations will be determined by the Engineer 37 in accordance with WSDOT FOP for AASHTO T716. 38 39 5-04.3(10)C2 HMA Compaction Statistical Evaluation – 40 Acceptance Testing 41 Comply with Section 1-06.2(1). 42

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 38 1 The location of HMA compaction acceptance tests will be randomly 2 selected by the Contracting Agency from within each sublot, with one 3 test per sublot. The Contracting Agency will determine the random 4 sample location using WSDOT Test Method T 716. 5 6 Use Table 16 to determine compaction acceptance test procedures and 7 to allocate compaction acceptance sampling and testing 8 responsibilities between the Contractor and the Contracting Agency. 9 HMA cores shall be taken or nuclear density testing shall occur after 10 completion of the finish rolling, prior to opening to traffic, and on the 11 same day that the mix is placed. 12 Table 16 HMA Compaction Acceptance Testing Procedures and Responsibilities When Contract Includes Bid When Contract Does Not Item “HMA Core Include Bid Item “HMA Core –

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 39 1The core diameter shall be 4-inches unless otherwise approved by the Engineer. 2The Contractor shall take the core samples in the presence of the Engineer, at locations designated by the Engineer, and deliver the core samples to the Contracting Agency. 3The Contracting Agency will determine, in its sole discretion, whether it will take cores or use the nuclear density gauge to determine in- place density. Exclusive reliance on cores for density acceptance is generally intended for small paving projects and is not intended as a replacement for nuclear gauge density testing on typical projects. 4The basis for test of all compaction sublots in a bridge compaction lot shall be cores. These cores shall be taken by the Contractor when the Proposal includes the bid item “HMA Cores – Bridge”. When there is no bid item for “HMA Cores – Bridge”, the Engineer will be responsible for taking HMA cores for all compaction sublots in a bridge compaction lot. In either case, the Engineer will determine core location, in-place density of the core, theoretical maximum density, rolling average of theoretical maximum density, and percent compaction using the procedure called for in this Section. 1 2 When using the nuclear density gauge for acceptance testing of 3 pavement density, the Engineer will follow WSDOT SOP 730 for 4 correlating the nuclear gauge with HMA cores. When cores are 5 required for the correlation, coring and testing will be by the Contracting 6 Agency. When a core is taken for gauge correlation at the location of a 7 sublot, the relative density of the core will be used for the sublot test 8 result and is exempt from retesting. 9 10 5-04.3(10)C3 HMA Statistical Compaction – Price Adjustments 11 For each HMA compaction lot (that is accepted by Statistical 12 Evaluation) which has less than three compaction sublots, for which all 13 compaction sublots attain a minimum of 91 percent compaction 14 determined in accordance with WSDOT FOP for AASHTO T 355 (or 15 WSDOT SOP 736 when provided by the Contract), the HMA will be 16 accepted at the unit Contract price with no further evaluation. 17 18 For each HMA compaction lot (that is accepted by Statistical 19 Evaluation) which does not meet the criteria in the preceding 20 paragraph, the compaction lot shall be evaluated in accordance with 21 Section 1-06.2(2) to determine the appropriate Compaction Price 22 Adjustment (CPA). All of the test results obtained from the acceptance 23 samples from a given compaction lot shall be evaluated collectively. 24 Additional testing by either a nuclear density gauge or cores will be 25 completed as required to provide a minimum of three tests for 26 evaluation. 27 28 For the statistical analysis in Section 1-06.2, use the following values: 29 30 x = Percent compaction of each sublot 31 USL = 100 32 LSL= 91 33

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 40 1 Each CPA will be determined as follows: 2 3 CPA = [0.40 x (CPF – 1.00)] x Q x UP 4 5 Where 6 7 CPA = Compaction Price Adjustment for the compaction lot ($) 8 CPF = Composite Pay Factor for the compaction lot (maximum 9 is 1.05) 10 Q = Quantity in the compaction lot (tons) 11 UP = Unit price of the HMA in the compaction lot ($/ton) 12 13 5-04.3(10)C4 HMA Statistical Compaction – Requests for 14 Retesting 15 For a compaction sublot that has been tested with a nuclear density 16 gauge that did not meet the minimum of 91 percent of the theoretical 17 maximum density in a compaction lot with a CPF below 1.00 and thus 18 subject to a price reduction or rejection, the Contractor may request 19 that a core, taken at the same location as the nuclear density test, be 20 used for determination of the relative density of the compaction sublot. 21 The relative density of the core will replace the relative density 22 determined by the nuclear density gauge for the compaction sublot and 23 will be used for calculation of the CPF and acceptance of HMA 24 compaction lot. When cores are taken by the Contracting Agency at the 25 request of the Contractor, they shall be requested by noon of the next 26 workday after the test results for the compaction sublot have been 27 provided or made available to the Contractor. Traffic control shall be 28 provided by the Contractor as requested by the Engineer. Failure by 29 the Contractor to provide the requested traffic control will result in 30 forfeiture of the request for retesting. When the CPF for the compaction 31 lot based on the results of the cores is less than 1.00, the Contracting 32 Agency will deduct the cost for the coring from any monies due or that 33 may become due the Contractor under the Contract at the rate of $200 34 per core and the Contractor shall pay for the cost of the traffic control. 35 36 5-04.3(10)D HMA Compaction – Visual Evaluation 37 Visual Evaluation will be the basis of acceptance for compaction of the Bid 38 items “HMA for Pavement Repair Cl. ___ PG ___”and “HMA for Prelevelling 39 Class___ PG___”. This HMA shall be thoroughly compacted to the 40 satisfaction of the Engineer. HMA that is used to prelevel wheel ruts shall 41 be compacted with a pneumatic tire roller. 42 43 5-04.3(10)E HMA Compaction – Test Point Evaluation 44 When compaction acceptance is by Test Point Evaluation, compact HMA 45 based on a test point evaluation of the compaction train. Perform the test 46 point evaluation in accordance with instructions from the Engineer. The 47 number of passes with an approved compaction train, required to attain the 48 maximum test point density, shall be used on all subsequent paving. 49

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 41 1 5-04.3(10)F HMA Compaction Acceptance – Notification of 2 Acceptance Test Results 3 The obligations and responsibilities for notifying the Contractor of 4 compaction acceptance test results are the same as for mixture acceptance 5 test results. See Section 5-04.3(9)E. 6 7 5-04.3(11) Reject Work 8 This Section applies to HMA and all requirements related to HMA (except 9 aggregates prior to being incorporated into HMA). For rejection of aggregate 10 prior to its incorporation into HMA refer to Section 3-04. 11 12 5-04.3(11)A Reject Work – General 13 Work that is defective or does not conform to Contract requirements shall 14 be rejected. The Contractor may propose, in writing, alternatives to removal 15 and replacement of rejected material. Acceptability of such alternative 16 proposals will be determined at the sole discretion of the Engineer. 17 18 5-04.3(11)B Rejection by Contractor 19 The Contractor may, prior to acceptance sampling and testing, elect to 20 remove any defective material and replace it with new material. Any such 21 new material will be sampled, tested, and evaluated for acceptance. 22 23 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 24 The Engineer may, without sampling, reject any batch, load, or section of 25 Roadway that appears defective. Material rejected before placement shall 26 not be incorporated into the pavement. 27 28 No payment will be made for the rejected materials or the removal of the 29 materials unless the Contractor requests the rejected material to be tested. 30 If the Contractor requests testing, acceptance will be by Statistical 31 Evaluation, and a minimum of three samples will be obtained and tested. 32 When uncompacted material is required for testing but not available, the 33 Engineer will determine random sample locations on the roadway in 34 accordance with WSDOT Test Method T 716, take cores in accordance with 35 WSDOT SOP 734, and test the cores in accordance with WSDOT SOP 737. 36 37 If the CPF for the rejected material is less than 0.75, no payment will be 38 made for the rejected material; in addition, the cost of sampling and testing 39 shall be borne by the Contractor. If the CPF is greater than or equal to 0.75, 40 the cost of sampling and testing will be borne by the Contracting Agency. If 41 the material is rejected before placement and the CPF is greater than or 42 equal to 0.75, compensation for the rejected material will be at a CPF of 43 0.75. If rejection occurs after placement and the CPF is greater than or 44 equal to 0.75, compensation for the rejected material will be at the 45 calculated CPF with an addition of 25 percent of the unit Contract price 46 added for the cost of removal and disposal. 47 48 5-04.3(11)D Rejection – A Partial Sublot (Mixture or Compaction) 49 In addition to the random acceptance sampling and testing, the Engineer 50 may also isolate from a mixture or compaction sublot any material that is 51 suspected of being defective in relative density, gradation or asphalt binder 52 content. Such isolated material will not include an original sample location.

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 42 1 The Contracting Agency will obtain a minimum of three random samples of 2 the suspect material and perform the testing. When uncompacted material 3 is required for testing but is not available, the Engineer will select random 4 sample locations on the roadway in accordance with WSDOT Test Method 5 T 716, take cores samples in accordance with WSDOT SOP 734, and test 6 the material in accordance with WSDOT SOP 737. The material will then be 7 statistically evaluated as an independent lot in accordance with Section 1- 8 06.2(2). 9 10 5-04.3(11)E Rejection – An Entire Sublot (Mixture or Compaction) 11 An entire mixture or compaction sublot that is suspected of being defective 12 may be rejected. When this occurs, a minimum of two additional random 13 samples from this sublot will be obtained. When uncompacted material is 14 required for the additional samples but the material has been compacted, 15 the Contracting Agency will take and test cores from the roadway as 16 described in Section 5-04.3(11)D. The additional samples and the original 17 sublot will be evaluated as an independent lot in accordance with Section 18 1-06.2(2). 19 20 5-04.3(11)F Rejection - A Lot in Progress (Mixture or Compaction) 21 The Contractor shall shut down operations and shall not resume HMA 22 placement until such time as the Engineer is satisfied that material 23 conforming to the Specifications can be produced when: 24 25 1. the Composite Pay Factor (CPF) of a mixture or compaction lot in 26 progress drops below 1.00 and the Contractor is taking no 27 corrective action, or 28 29 2. the Pay Factor (PFi) for any constituent of a mixture or compaction 30 lot in progress drops below 0.95 and the Contractor is taking no 31 corrective action, or 32 33 3. either the PFi for any constituent (or the CPF) of a mixture or 34 compaction lot in progress is less than 0.75. 35 36 5-04.3(11)G Rejection – An Entire Lot (Mixture or Compaction) 37 An entire lot with a CPF of less than 0.75 will be rejected. 38 39 5-04.3(12) Joints 40 5-04.3(12)A HMA Joints 41 5-04.3(12)A1 Transverse Joints 42 Conduct operations such that placement of the top or wearing course 43 is a continuous operation or as close to continuous as possible. 44 Unscheduled transverse joints will be allowed, but the roller may pass 45 over the unprotected end of the freshly laid HMA only when the 46 placement of the course is discontinued for such a length of time that 47 the HMA will cool below compaction temperature. When the Work is 48 resumed, cut back the previously compacted HMA to produce a slightly 49 beveled edge for the full thickness of the course. 50 51 Construct a temporary wedge of HMA on a 50H:1V where a transverse 52 joint as a result of paving or planing is open to traffic. Separate the HMA

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 43 1 in the temporary wedge from the permanent HMA upon which it is 2 placed by strips of heavy wrapping paper or other methods approved 3 by the Engineer. Remove the wrapping paper and trim the joint to a 4 slightly beveled edge for the full thickness of the course prior to 5 resumption of paving. 6 7 Waste the material that is cut away and place new HMA against the 8 cut. Use rollers or tamping irons to seal the joint. 9 10 5-04.3(12)A2 Longitudinal Joints 11 Offset the longitudinal joint in any one course from the course 12 immediately below by not more than 6 inches nor less than 2 inches. 13 Locate all longitudinal joints constructed in the wearing course at a lane 14 line or an edge line of the Traveled Way. Construct a notched wedge 15 joint along all longitudinal joints in the wearing surface of new HMA 16 unless otherwise approved by the Engineer. The notched wedge joint 17 shall have a vertical edge of not less than the maximum aggregate size 18 nor more than ½ of the compacted lift thickness, and then taper down 19 on a slope not steeper than 4H:1V. Uniformly compact the sloped 20 portion of the HMA notched wedge joint. 21 22 On one-lane ramps a longitudinal joint may be constructed at the center 23 of the traffic lane, subject to approval by the Engineer, if: 24 25 1. The ramp must remain open to traffic, or 26 27 2. The ramp is closed to traffic and a hot-lap joint is constructed. 28 29 a.

A lot is defined as the total quantity of material or work produced 27 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 28 equal to one day’s production or 800 tons, whichever is less except that the final sublot 29 will be a minimum of 400 tons and may be increased to 1200 tons. 30 31 All of the test results obtained from the acceptance samples from a given lot shall be 32 evaluated collectively. If the Contractor requests a change to the JMF that is approved, 33 the material produced after the change will be evaluated on the basis of the new JMF for 34 the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot 35 in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 36 after the Engineer is satisfied that material conforming to the Specifications can be 37 produced. 38 39 Sampling and testing for evaluation shall be performed on the frequency of one sample 40 per sublot. 41 42 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling 43 Samples for acceptance testing shall be obtained by the Contractor when ordered by the 44 Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer 45 and in accordance with AASH-TO T 168. A minimum of three samples should be taken 46 for each class of HMA placed on a project. If used in a structural application, at least one 47 of the three samples shall to be tested.

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 182 1 CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup 2 samples of the existing sublots or samples from the Roadway shall be tested to provide 3 a minimum of three sets of results for evaluation. 4 5 5-04.3(9)C5 Vacant 6 7 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments 8 For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated 9 CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The 10 NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The 11 total job mix compliance price adjustment will be calculated as the product of the NCMF, 12 the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. 13 14 If a constituent is not measured in accordance with these Specifications, its individual 15 pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 16 17 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests 18 The Contractor may request a sublot be retested. To request a retest, the Contractor 19 shall submit a written request within 7 calendar days after the specific test results have 20 been received. A split of the original acceptance sample will be retested. The split of the 21 sample will not be tested with the same tester that ran the original acceptance test. The 22 sample will be tested for a complete gradation analysis, asphalt binder content, and, at 23 the option of the agency, Va. The results of the retest will be used for the acceptance of 24 the HMA in place of the original sublot sample test results. The cost of testing will be 25 deducted from any monies due or that may come due the Contractor under the Contract 26 at the rate of $500 per sample. 27 28 5-04.3 (9)D Mixture Acceptance – Commercial Evaluation 29 If sampled and tested, HMA produced under Commercial Evaluation and having all 30 constituents falling within the tolerance limits of the job mix formula shall be accepted at 31 the unit Contract price with no further evaluation. When one or more constituents fall 32 outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the 33 lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate 34 CPF. The commercial tolerance limits will be used in the calculation of the CPF and the 35 maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 36 existing sublots or samples from the street shall be tested to provide a minimum of three 37 sets of results for evaluation. 38 39 For each lot of HMA mix produced and tested under Commercial Evaluation when the 40 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be 41 determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 42 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product 43 of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of 44 mix. 45 46 If a constituent is not measured in accordance with these Specifications, its individual 47 pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 48

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 183 1 5-04.3(10) HMA Compaction Acceptance 2 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 3 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 4 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 5 specified level of relative density. The specified level of relative density shall be a 6 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with 7 Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). 8 The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The 9 specified level of density attained will be determined by the evaluation of the density of 10 the pavement. The density of the pavement shall be determined in accordance with 11 WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of 12 the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using 13 cores to determine density. 14 15 Tests for the determination of the pavement density will be taken in accordance with the 16 required procedures for measurement by a nuclear density gauge or roadway cores after 17 completion of the finish rolling. 18 19 If the Contracting Agency uses a nuclear density gauge to determine density the test 20 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the 21 mix is placed and prior to opening to traffic. 22 23 Roadway cores for density may be obtained by either the Contracting Agency or the 24 Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches 25 minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by 26 the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. 27 28 If the Contract includes the Bid item “Roadway Core” the cores shall be obtained by the 29 Contractor in the presence of the Engineer on the same day the mix is placed and at 30 locations designated by the Engineer. If the Contract does not include the Bid item 31 “Roadway Core” the Contracting Agency will obtain the cores. 32 33 For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s 34 request after the Engineer is satisfied that material conforming to the Specifications can 35 be produced. 36 37 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 38 other than those listed above shall be compacted on the basis of a test point evaluation 39 of the compaction train. The test point evaluation shall be performed in accordance with 40 instructions from the Engineer. The number of passes with an approved compaction 41 train, required to attain the maximum test point density, shall be used on all subsequent 42 paving. 43 44 HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling 45 wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved 46 by the Engineer. 47 48 Test Results

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 184 1 For a sublot that has been tested with a nuclear density gauge that did not meet the 2 minimum of 92 percent of the reference maximum density in a compaction lot with a CPF 3 below 1.00 and thus subject to a price reduction or rejection, the Contractor may request 4 that a core be used for determination of the relative density of the sublot. The relative 5 density of the core will replace the relative density determined by the nuclear density 6 gauge for the sublot and will be used for calculation of the CPF and acceptance of HMA 7 compaction lot. 8 9 When cores are taken by the Contracting Agency at the request of the Contractor, they 10 shall be requested by noon of the next workday after the test results for the sublot have 11 been provided or made available to the Contractor. Core locations shall be outside of 12 wheel paths and as determined by the Engineer. Traffic control shall be provided by the 13 Contractor as requested by the Engineer. Failure by the Contractor to provide the 14 requested traffic control will result in forfeiture of the request for cores. When the CPF for 15 the lot based on the results of the HMA cores is less than 1.00, the cost for the coring will 16 be deducted from any monies due or that may become due the Contractor under the 17 Contract at the rate of $200 per core and the Contractor shall pay for the cost of the 18 traffic control. 19 20 5-04.3(10)A HMA Compaction – General Compaction Requirements 21 Compaction shall take place when the mixture is in the proper condition so that no undue 22 displacement, cracking, or shoving occurs. Areas inaccessible to large compaction 23 equipment shall be compacted by other mechanical means. Any HMA that becomes 24 loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in any way 25 defective, shall be removed and replaced with new hot mix that shall be immediately 26 compacted to conform to the surrounding area. 27 28 The type of rollers to be used and their relative position in the compaction sequence 29 shall generally be the Contractor’s option, provided the specified densities are attained. 30 Unless the Engineer has approved otherwise, rollers shall only be operated in the static 31 mode when the internal temperature of the mix is less than 175°F. Regardless of mix 32 temperature, a roller shall not be operated in a mode that results in checking or cracking 33 of the mat. Rollers shall only be operated in static mode on bridge decks. 34 35 5-04.3(10)B HMA Compaction – Cyclic Density 36 Low cyclic density areas are defined as spots or streaks in the pavement that are less 37 than 90 percent of the theoretical maximum density. At the Engineer’s discretion, the 38 Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will 39 follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for 40 any 500-foot section with two or more density readings below 90 percent of the 41 theoretical maximum density. 42 43 5-04.3(10)C Vacant 44 45 5-04.3(10)D HMA Nonstatistical Compaction 46 47 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots

HMA OVERLAY (2019) Skagit County Project #ESHMA19-1 July 2019 185 1 HMA compaction which is accepted by nonstatistical evaluation will be based on 2 acceptance testing performed by the Contracting Agency dividing the project into 3 compaction lots. 4 5 A lot is represented by randomly selected samples of the same mix design that will be 6 tested for acceptance. A lot is defined as the total quantity of material or work produced 7 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 8 equal to one day’s production or 400 tons, whichever is less except that the final sublot 9 will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction 10 will be at the rate of 5 tests per sublot per WSDOT T 738. 11 12 The sublot locations within each density lot will be determined by the Engineer. For a lot 13 in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 14 after the Engineer is satisfied that material conforming to the Specifications can be 15 produced. 16 17 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 18 other than those listed above shall be compacted on the basis of a test point evaluation 19 of the compaction train. The test point evaluation shall be performed in accordance with 20 instructions from the Engineer. The number of passes with an approved compaction 21 train, required to attain the maximum test point density, shall be used on all subsequent 22 paving. 23 24 HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel 25 ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the 26 Engineer. 27 28 5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation – Acceptance Testing 29 The location of the HMA compaction acceptance tests will be randomly selected by the 30 Engineer from within each sublot, with one test per sublot. 31 32 5-04.3(10)D3 HMA Nonstatistical Compaction – Price Adjustments 33 For each compaction lot with one or two sublots, having all sublots attain a relative 34 density that is 92 percent of the reference maximum density the HMA shall be accepted 35 at the unit Contract price with no further evaluation. When a sublot does not attain a 36 relative density that is 92 percent of the reference maximum density, the lot shall be 37 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 38 maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will 39 be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF 40 lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by 41 either a nuclear moisture-density gauge or cores will be completed as required to provide 42 a minimum of three tests for evaluation. 43 44 For compaction below the required 92% a Non-Conforming Compaction Factor (NCCF) 45 will be determined. The NCCF equals the algebraic difference of CPF minus 1.00 46 multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the 47 product of CPF, the quantity of HMA in the compaction control lot in tons, and the unit 48 Contract price per ton of mix.

Acceptability of such alternative proposals will be determined at the 8 sole discretion of the Engineer. HMA that has been rejected is subject to the 9 requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit 10 a corrective action proposal to the Engineer for approval. 11 12 5-04.3(11)B Rejection by Contractor 13 The Contractor may, prior to sampling, elect to remove any defective material and 14 replace it with new material. Any such new material will be sampled, tested, and 15 evaluated for acceptance. 16 17 5-04.3(11)C Rejection Without Testing (Mixture or Compaction) 18 The Engineer may, without sampling, reject any batch, load, or section of Roadway that 19 appears defective. Material rejected before placement shall not be incorporated into the 20 pavement. Any rejected section of Roadway shall be removed. 21 22 No payment will be made for the rejected materials or the removal of the materials 23 unless the Contractor requests that the rejected material be tested. If the Contractor 24 elects to have the rejected material tested, a minimum of three representative samples 25 will be obtained and tested. Acceptance of rejected material will be based on 26 conformance with the nonstatistical acceptance Specification. If the CPF for the rejected 27 material is less than 0.75, no payment will be made for the rejected material; in addition, 28 the cost of sampling and testing shall be borne by the Contractor. If the CPF is greater 29 than or equal to 0.75, the cost of sampling and testing will be borne by the Contracting 30 Agency. If the material is rejected before placement and the CPF is greater than or equal 31 to 0.75, compensation for the rejected material will be at a CPF of 0.75. If rejection 32 occurs after placement and the CPF is greater than or equal to 0.75, compensation for 33 the rejected material will be at the calculated CPF with an addition of 25 percent of the 34 unit Contract price added for the cost of removal and disposal. 35 36 5-04.3(11)D Rejection - A Partial Sublot 37 In addition to the random acceptance sampling and testing, the Engineer may also 38 isolate from a normal sublot any material that is suspected of being defective in relative 39 density, gradation or asphalt binder content. Such isolated material will not include an 40 original sample location. A minimum of three random samples of the suspect material will 41 be obtained and tested. The material will then be statistically evaluated as an 42 independent lot in accordance with Section 1-06.2(2). 43 44 5-04.3(11)E Rejection - An Entire Sublot 45 An entire sublot that is suspected of being defective may be rejected.
