• Abstract:
  This report presents the findings and recommendations based on the Evaluation of Geosynthetics in Asphalt Overlays of Jointed Concrete Pavements. This project evaluated Linq Tac-711N and Strata Grid-200?s ability to ease distress and reflective cracking in the asphalt overlay at the Portland Cement Concrete (PCC) joints.
  
  The Department researchers established a test section south of MRM 14 on Interstate 29 near Elk Point, South Dakota. The test section was 2.2 kilometers (1.4 miles) long and contained 120 joints in both the passing lane and driving lane. The section was split into twelve segments with different materials, rehabilitations, and joint treatments. Each segment consisted of ten joints. Every joint was monitored to determine the amount of movement and the amount of joint and shoulder cracks, which reflected through the asphalt overlay adjacent to each joint. The monitoring occurred during warm and cold weather over a three-year period.
  
  A literature search was performed to see whether any other states had conducted similar research.
  
  Following the literature search, the field data that was collected was analyzed to determine the performance of each fabric, concrete rehabilitation technique, and treatment for joints in the asphalt concrete overlay.
  
  At the conclusion of the project, recommendations were made based on the results of the study of geosynthetics in asphalt overlays on Interstate 29 and other state Department of Transportation?s reports.
