This document provides guidelines and information for documenting construction activities for the Specific Pavement Studies-10 (SPS-10) experiment warm-mix asphalt (WMA) study. These guidelines should be followed by the Federal Highway Administration (FHWA) Long-Term Pavement Performance (LTPP) regional support contractor (RSC) when working with State and Provincial highway agencies in documenting SPS-10 construction activities. Properly documenting the construction activities for each SPS-10 project in a stand-alone construction report is critical to future analysis efforts.

The purpose of this volume of the report series is to document the guidelines and information for detailing construction activities for the SPS-10 experiment for the LTPP program. The SPS-10 experiment is designed to capture information on the short- and long-term performance of WMA relative to 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 allow both user-agencies and researchers a better understanding of the potential benefits of WMA. Collectively, this information could be used for performance prediction.
