A Study on Warm-Mix Asphalt

The Illinois Department of Transportation (IDOT) had an immediate need to evaluate the performance characteristics of new asphalt mixtures. The new mixtures included warm mix asphalt (WMA), stone-matrix asphalt (SMA) with recycled asphalt shingles (RAS), and asphalt mixtures containing alternate friction aggregates (diabase, quartzite, and granite). The object of this project was to compare these new mixes and to provide IDOT with guidance on the applicability of the mix designs when implementing these mixtures in the future. 17.Illinois Department of Transportation ICT R27-SP17published or submitted for publicationnot peer reviewe
