Warm Mix Asphalt Final Report

The performance of pavements constructed using warm mix asphalt (WMA) technology were compared to the performance of conventional hot mix asphalt (HMA) pavements placed on the same project. Measurements of friction resistance, rutting/wear, ride and pavement condition (alligator, longitudinal and transverse cracking) did not show that the WMA either improved or worsened performance. WMA is an allowable substitute for conventional HMA on all projects using less than 20 percent recycled asphalt pavement (RAP). WMA is not allowed when the RAP content exceeds 20 percent or when any percentage of recycled asphalt shingles (RAS) is incorporated.
