Evaluate Thick Lift High Performance Grade (HPG) Mixes for Intersections, Border Checkpoints, and Other Locations with Slow Moving Heavy Traffic

Several Districts of the Texas Department of Transportation (TxDOT) recently reported rutting problems greater than 2 inches at intersections, border checkpoints, and other locations where heavy truck traffic either moves very slowly or is stationary while waiting in queues, even though the best mixes (e.g., stone matrix asphalt) were used. There is an urgent need to address such premature rutting problem in those places in a timely manner. The research team will identify and evaluate the suitable mixes and single lift construction technique to avoid premature rutting failures at those places, resulting in major cost savings and reducing wet weather accidents. The research team will review literature to identify the critical factors for improving mix rutting resistance. Based on the findings from the literature, the research team will develop and execute an experimental design to identify the suitable mixes for the slow-moving heavy traffic and then construct field trials with those mixes in a single thick lift and follow up their field performance. In the end, the research team will recommend specification changes and develop guidelines for constructing single thick lift with suitable mixes at intersections, border checking points, or other places.
