              Abstract:This report documents all activities performed as part of the Long-Term Pavement Performance (LTPP) program’s Warm-Mix Asphalt (WMA) Study. The report describes the overall conduct of the project with a focus on the guidelines for recruitment, selection, implementation, construction, sampling, testing, and monitoring of the LTPP Specific Pavement Studies (SPS)-10 “WMA Overlay of Asphalt Pavement” experiment.



This experiment is designed to capture information on the short- and long-term performance of WMA relative to Hot-Mix Asphalt (HMA). This experiment has been structured to ensure consistency and compatibility with the existing LTPP program objectives and database while addressing information gaps regarding WMA performance. The intent of the SPS-10 experiment is to capture not only field performance but also laboratory test data that will provide both user-agencies and researchers a better understanding of the potential benefits of WMA. Collectively, this information could be used for performance prediction.
