This report presents the guidelines for the development and implementation of a material-sampling and testing program for each test site included in the Specific Pavement Studies (SPS)-10 warm-mix asphalt (WMA) study. These guidelines should be followed by a Federal Highway Administration (FHWA) Long-Term Pavement Performance (LTPP) regional support contractor to develop a material-sampling and testing plan tailored to each SPS-10 project.

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.
