I. EXECUTIVE SUMMARY
Enclosed is a summary of the pavement management that was performed by WSB for the City of Vadnais Heights. This report gives an overview of the road condition in the City and it is intended to serve as a guidance in pavement management and project planning.
Pavement conditions of all the roadways in the City’s network were rated in June 2019. Roadways inspected and evaluated only include bituminous roadways that are maintained by the City. Pavement ratings were completed using PAVER, which is a pavement management software that calculates Pavement Condition Index (PCI) based on the distresses identified in the field. PCI is based on a 0 to 100 scale, with 100 being a road in perfect condition. Any type of road maintenance (i.e. patching or crack sealing) performed prior to inspections would be accounted for in each PCI.
The significant findings of the pavement condition are as follows:
• There are currently 41 miles of bituminous roadways inspected in the City of Vadnais Heights. • The current weighted average PCI in the City is 73.5 in 2019. • Percentage of bituminous roadways in respective condition category, in terms of length, are as follows: o “Excellent” category requiring preventative maintenance – 30% o “Good” category requiring preservation – 32% o “Fair” category requiring more robust preservation methods – 22% o “Poor” category requiring continuous monitoring – 7% o “Very poor” category requiring reclamation or complete reconstruction – 8%
The findings reflect that a majority of the roadways are in good condition. Three scenarios were run to determine the average annual budget required to maintain the streets in the network at different levels of PCI. Maintenance protocol was applied to the roadways based on the visual ratings and unit pricing was obtained based on estimated pricing from several cities in the Metro area.
In order to maintain the streets in the City at current weighted average PCI, which is 73.5 PCI, an average annual funding of $1.8 million would be required. An average annual budget of $1.55 million and $2.0 million would be required to maintain the roadways at 68 PCI and 78 PCI respectively. Future references to the dollar amounts contained in this report in reference to maintenance activities would be based on 2019 dollars. Maintaining at a higher level of condition would require a higher annual budget and vice versa. We would recommend the City to at least maintain the roadways at the current condition using the “do best first” approach, which the City would allocate substantial funding to perform preventative maintenance to delay the deterioration of roadways in good condition in addition to conducting preservation, reclamation, or reconstruction to improve the roadway conditions.

II. INTRODUCTION
A pavement management program includes a systematic method of inspecting and rating the pavement condition of roads in a network, followed by performing a cost-effective analysis of various maintenance and rehabilitation strategies, which assists decision makers in making the best decision on the use of available resources. The pavement management ideology, if successfully implemented, can result in drastic improvement of the life cycle costs and performance of the roads. The main objectives of a pavement management program are to maintain a high-level network, evaluate the effectiveness of different alternative, and optimize timing of maintenance and construction activities. These objectives can be met by routinely carrying out inspections and documenting the condition of roads in the City’s network. The data is typically managed within a pavement management software, which can manage, sort, and store the collected information.
This Pavement Management Report is comprised of the following components:
• a condition report containing an assessment of the current pavement conditions with recommended maintenance and rehabilitation activities based on visual inspections; and • different budget scenarios that can serve as a guidance to the City for future planning and financing of the activities.
Decisions made on certain maintenance or rehabilitation activity is recommended to be accompanied by a pavement forensic investigation. Pavement forensics identifies the pavement structure and condition under the visible layer of the pavement, such as the depths of pavement layers, signs of bonding and debonding, and distresses that might not be visible from the surface. Soil borings along the roadways can be used to identify aggregate depths and soil classifications to provide a better understanding of the roadway segments in determining the appropriate pavement rehabilitation technique.

III. PAVEMENT CONDITION SUMMARY
A. INTRODUCTION
Pavement Condition Index (PCI) was used to measure pavement condition on a scale of 0 to 100, with 100 being a perfect roadway with no distresses. Engineering staff has established the PCI categories in Table III.A to describe the conditions of the bituminous roadways.
Table III.A. PCI condition categories established for the City of Vadnais Heights.
Condition PCI Range Recommended Maintenance Strategy Category
Preventative Maintenance Excellent 90 – 100 (Crack Seal, Chip Seal, Fog Seal, Micro- Surfacing)
1-inch to 1.5-inch Mill and Overlay, Good 70 – 89 Overlay, Texas Underseal
Fair 50 – 69 2-inch or Greater Mill and Overlay
Poor 40 – 49 Monitor
Very Poor 0 – 39 Reclamation / Reconstruction
PAVER, which is an asset management software, was used to record and estimate the conditions of the roadways. The software calculates PCI based on the distress type, distress severity, and distress quantity. Examples of distress type are alligator cracking, pothole, and longitudinal and transverse cracking. Distress severity is divided into low, moderate, and high. Distress quantity is either the number of counts, length, or area depending on the distress type.
The PCI values obtained were based on visual inspection and the recommended strategies shall only be used as guidelines in determining the appropriate maintenance for a certain roadway. Additional pavement investigation such as pavement forensics may be needed to obtain information on the subsurface of the roadways.

IV. MAINTENANCE AND REHABILITATION ACTIVITIES
Implementing a proper maintenance strategy is both cost effective and appropriate since maintenance costs increase with pavement age. By applying the appropriate maintenance at the right time, it can prolong the life of the existing pavement in a most cost-effective way.
A. PREVENTATIVE MAINTENANCE
Crack Seal
Crack sealing is a type of preventative maintenance performed to prevent the intrusion of water and incompressible materials into cracks. When water enters the cracks, it can soften the sub-base and base layers and lead to further cracking and the development of more severe alligator cracking and subsequently the formation of potholes. In Minnesota where freeze/thaw cycles exist, the water that enters the system through cracks can lead to frost heaving issues. Crack sealing should be completed as preventative maintenance early in the life of a new pavement or overlay, typically within 2 to 4 years or sooner if cracks develop, and roughly every 7 years or as determined to be necessary. This technique will not improve the structural capacity of the pavement but will slow down future structural deterioration that could be caused when water enters the system. It is recommended that crack sealing is done prior to either fog sealing or chip sealing.
Fog Seal
Fog sealing is a type of preventative maintenance in which only the asphalt emulsion is applied to the roadway to protect the surface from environmental aging, moisture damage, and oxidation. This preventative maintenance technique will not add any strength to the pavement. Fog sealing is normally completed one year after crack sealing. Typically, a fog seal will last 3 to 5 years. It is important to note that while the color of a fog seal may fade as early as a year after its application, a fog seal remains effective for as many as 2 to 4 years. WSB would recommend the City reference MnDOT Spec 2355 for more information on fog sealing guidelines.
Chip Seal
Chip sealing process involves an application of a uniform layer of emulsified asphalt followed immediately by a layer of cover aggregate across the pavement surface. Pre- sweeping and filling of all cracks shall be done prior to the chip seal application. Chip sealing creates a waterproof surface membrane to the existing membrane, which helps to slow down the deterioration of the pavement from oxidation as well as to prevent the intrusion of water. Chip sealing is typically completed one year after crack sealing. Normally, a good chip seal placed on a newer road can last 5 to 10 years. This assumes the chip seal is protected during placement to allow proper time to cure. Other factors which affect a chip seals performance include the type of binder that is used, the condition of the underlying road and external factors such as plow damage. It is the responsibility of the owner to ensure that these external factors do not contribute to premature failure of a chip seal. It is important to note that chip seals can be effective if constructed properly and if placed on a road that is a good candidate for chip seal. Field surveys will assist in determining which roads are candidates for a chip seal. WSB would recommend the City to reference MnDOT Spec 2356 or the 2006 Minnesota Chip Seal Handbook for guidelines to use when chip sealing.
Micro-surfacing
Micro-surfacing is a mix of crushed aggregate, mineral filler, additives, water, and polymer- modified emulsified asphalt. A micro-surfacing treatment can be expected to extend a
Section IV Page 9
roadway’s life by 3 to 6 years, depending on the number of layers applied and the condition of the existing roadway. It is applied by a truck equipped with a squeegee or spreader box. Micro surfacing is effective at sealing low-severity cracks, including fatigue cracks, longitudinal cracking, and transverse cracking. It also addresses raveling, friction loss, moisture infiltration, bleeding, and roughness. This treatment is often chosen to inhibit raveling and oxidation, as well as improving surface friction and filling minor irregularities and rutting in a roadway. WSB would recommend the City reference MnDOT Spec 2354 for more information on micro-surfacing guidelines.
B. PAVEMENT PRESERVATION
Overlay/Mill and Overlay
An overlay involves placing a new layer of bituminous material on top of the existing asphalt surface, while a mill and overlay involves grinding all or a portion of the asphalt surface in place and topping it with bituminous course(s) over the entire surface. This type of action provides a structural improvement to the roadway. It would be our recommendation to do more investigative work such as pavement coring to investigate subsurface material and conditions prior to a mill and overlay project. Pavement coring identifies what exists underneath the visible layer of the pavement and can give a wealth of information including depths of the pavement layers, signs of bonding or debonding, and distresses that might not be visible from the road surface.
Texas Underseal
Texas Underseal (TUS) is a non-conventional pavement preservation method, which a chip seal is placed under an overlay. The chip seal layer will act as stress relief membrane that will provide good cracking resistance to the asphalt layer. This layer also helps to prevent the intrusion of moisture into the underlying asphalt pavement. TUS is also effective in delaying reflective cracking. It is recommended to use an asphalt binder that is less prone to cracking, and in our case in Minnesota, it would be a -34 PG asphalt binder. If paving of HMA is taking place on the same day, do not tack or fog seal the TUS. If there will be a period of time before the paving of HMA occurs, fog seal the underseal layer to hold the loose rocks down together with the pavement surface. It is recommended to reference MnDOT Spec 2356 for bituminous underseal guidelines.
C. RECLAMATION/RECONSTRUCTION
There are two conventional types of reclamation, which are full depth reclamation (FDR) and stabilized full depth reclamation (SFDR). FDR involves grinding the asphalt pavement with a portion of the underlying base, followed by an overlay or a surface treatment. SFDR is FDR with the addition of stabilizing additives, which can be asphalt based, chemical based, or compaction aids. The asphalt additives can be foamed asphalt or asphalt emulsion. Reclamation brings the pavement to an absolute 100 (perfect condition) rating.
Reconstruction includes the complete removal of the existing pavement and subgrade removal and replacement to provide a sound structure for the new pavement. Subsurface water management is a significant component of a reconstruction project. Thus, addressing roadway drainage is included in roadway reconstruction projects. Reconstruction would also bring the pavement to an absolute 100 (perfect condition) rating.
Life expectancy of these reclamation and reconstruction projects are dependent on the ongoing maintenance such as crack maintenance and surface treatment, etc.

V. PAVEMENT LIFE CYCLE
Pavements have been constructed to meet the demands of traffic and the environment for respective design periods. However, traffic and time will slowly take their tolls on these newly constructed pavements causing the Pavement Condition Index (PCI) of the roadways to decline. Figure V.A shows the typical life expectancy of bituminous pavement developed. If the City does not conduct any major maintenance activity throughout the pavement life cycle, the pavement will eventually degrade and fail after an estimated 40 years since it was first constructed.

VI. CONDITION AND BUDGET SCENARIOS
A. CONDITION PERFORMANCE ANALYSIS
A condition performance analysis was performed on bituminous roadways over a period of 20 years. The curve was generated based on the PCI obtained at the time of inspection and PAVER was then utilized to predict the degradation of the pavements on the deterioration curve developed (Figure VI.A). As shown in the graph below, the weighted average PCI of all the roadways inspected will drop from 73.5 to approximately 33 in 20 years if no proper maintenance schedule has been implemented. The graph below also shows the weighted average PCI over the next 20 years for different annual budget scenarios.

B. MAINTENANCE AND REPAIR (M&R) WORK PLANNING MODELS
Maintenance cost increases considerably with the age of pavement. Thus, implementing a preventative maintenance strategy proves to be cost effective. Preventative maintenance activities such as crack sealing, fog sealing, and chip sealing are done at much lower costs compared to preservation actions such as mill and overlay. The main idea behind the preventative maintenance strategy is that applying the appropriate maintenance action at the right time will keep the good roads in good condition at a lower cost. This is often a better strategy than leaving the road to deteriorate over time before applying a fix. With the application of proper preventative techniques, the pavement life often can be extended, provided the maintenance is done in the correct time frame.
Using PAVER, the funding level needed to maintain the current weighted average PCI can be predicted. This dollar amount will continue to increase if a pavement management plan is not implemented. A good pavement management plan will budget for preventative maintenance to maintain the pavements in good condition, and for some of the roads in the system for reclamation or reconstruction to improve the structural capacity of the existing roadway. This is known as the “do best first” approach.
The maintenance activities listed in Table VI.A to be performed and the unit pricing was based on 2019 dollar.

C. PCI DRIVEN MODELS
Three scenarios were run to determine the budget required to maintain the target PCI levels of 68, 73.5 (current weighted average), and 78. These models also accounted for an inflation rate of 3%. Table VI.B shows the annual budget required to maintain the PCI at desired levels.
