INTRODUCTION 1.1 GENERAL Kleinfelder has completed the authorized subsurface exploration and geotechnical engineering evaluation for the proposed Will Rogers Turnpike Pavement Rehabilitation project located in Ottawa County, Oklahoma. The services provided were in general accordance with our proposal No. TUL 16P36625 dated March 14, 2016, authorized by our Agreement with Craig and Keithline, Inc., dated May 2, 2016 and executed on May 3, 2016. This report includes our recommendations related to the geotechnical aspects of the project design and construction. Additionally, Falling Weight Deflectometer (FWD) tests and the corresponding back-calculated data analyses were performed by ARA Inc. for this project. Conclusions and recommendations presented in the report are based on the subsurface information encountered at the locations of our exploration and the provisions and requirements outlined in the ADDITIONAL SERVICES and LIMITATIONS sections of this report. In addition, an article prepared by The Geoprofessional Business Association (GBA), Important Information About This Geotechnical Engineering Report , has been included in APPENDIX D. We recommend that all individuals read the report limitations along with the included GBA document. 1.2 PROPOSED CONSTRUCTION The proposed project is located on Will Rogers Turnpike, starting from at Milepost 316, approximately 180 feet west of South 590 Road overpass, and extends northeast four miles to Milepost 320, approximately 1,800 feet west of South 630 Road overpass. The alignment includes four Turnpike under Passes (TPUs) in each direction. The rehabilitation will include both the Eastbound and Westbound pavement sections of the Will Rogers Turnpike. We understand that the proposed rehabilitation will consist of mill/overlay of the existing pavement within the project limits. 20170366/ TUL16R45722 Page 1 of 16 August 25, 2016 © 2016 Kleinfelder The geotechnical exploration was performed for the purpose of determining the existing pavement thickness, subgrade soil properties and subsurface conditions of the existing pavement. A pavement condition survey was performed at 31 locations within the project alignment. FWD testing was performed by ARA, Inc. to determine the in-situ subgrade resilient modulus (Mr) and pavement modulus (Ep). The report prepared by ARA, Inc. is attached in Appendix C. The FWD testing was performed on the existing pavement in the outside wheel path at approximately 528- foot (0.1 mile) intervals in each lane in both directions. Additionally, three FWD tests were performed in each TPU areas in both directions. Therefore, a total of 108 FWD tests were performed for the whole project. In addition to the FWD tests by ARA Inc., Kleinfelder investigated the subsurface conditions by extracted pavement cores and subgrade soil samples at 33 locations. Laboratory testing of the samples were performed by Kleinfelder. Pavement section design recommendations have been developed based on traffic information provided by Craig & Keithline, Inc. This report has been prepared, and the corresponding work performed, in general accordance with the “2011 State of Oklahoma Department of Transportation (ODOT) Geotechnical Specifications for Roadway Design.” The scope of the exploration and engineering evaluation for this study, as well as the conclusions and recommendations in this report, were based on our understanding of the project as described above. If pertinent details of the project have changed or otherwise differ from our descriptions, we must be notified and engaged to review the changes and modify our recommendations, if needed. 20170366/ TUL16R45722 Page 2 of 16 August 25, 2016 © 2016 Kleinfelder 2. SITE CONDITIONS 2.1 SITE DESCRIPTION The site is located on Will Rogers Turnpike, starting from Milepost 316, approximately 180 feet west of South 590 Road overpass, and extends northeast four miles to Milepost 320, approximately 1,800 feet west of South 630 Road overpass in Ottawa County, Oklahoma. The general location of the site is shown in Figure 1, Site Location Diagram. The existing pavement on the Turnpike is a two-lane Asphaltic Concrete (AC) pavement with AC shoulders in both directions (eastbound and westbound). The surrounding areas were mostly firm pasture land with few residential properties. Existing
