Evaluation of New Technologies for Use in Warm Mix Asphalt

Abstract. Several new processes have been developed with the goal of reducing the mixing and compaction temperatures of hot mix asphalt without sacrificing the quality of the resulting pavement. Three potential Warm Mix Asphalt processes were evaluated in this study. They were Aspha-min®, Sasobit®, and Evotherm®.

PERFORMANCE EVALUATION OF WARM MIX ASPHALT

1.1 Warm Mix Asphalt Warm mix asphalt (WMA) is a rapidly expanding form of asphalt concrete, although it is somewhat akin to cold mix and warm mix approaches that have been available for decades. It differs from hot mix asphalt (HMA) only in the production temperatures required to meet appropriate standards of mixing and densification.
