Special Report from TRB 2014: Warm-Mix Asphalt

The use of warm-mix asphalt (WMA) is growing across the country. A survey conducted by the National Asphalt Pavement Association found that there was a twenty-six percent increase in WMA production in the 2012 construction season when compared to 2011. A high number of papers on WMA were presented at the 2014 Transportation Research Board annual meeting. The papers presented on WMA included an evaluation of WMA performance, which found it to be comparable to the performance of hot-mix asphalt; an assessment of a WMA modifier for open-graded friction courses; examinations of the use of reclaimed asphalt pavement mixes; and a study on sustainable concrete.
