Participate in the LTPP Warm-Mix Asphalt Study

The Federal Highway Administration's (FHWA) Long-Term Pavement Performance (LTPP) program is now recruiting test projects for a new warm-mix asphalt study.

“This is an excellent opportunity for highway agencies to learn about the long-term performance of different warm-mix asphalt technologies available today,” said Jack Springer of FHWA. Monitoring the mix design and construction of warm-mix asphalt pavements from the time of placement to the end of performance will provide valuable information on the benefits offered by the technology. Projects that will be constructed between 2014 and 2016 are eligible to participate in the study. The recruitment period runs until May 2014.
