Abstract

Warm Mix Asphalt (WMA) technology has become increasingly popular in pavement construction because of its environmental benefits and its ability to improve the engineering properties of asphalt binders and mixtures. This state-of-the-art article focuses on various aspects of the WMA technology incorporating Sasobit® which includes the rheological characteristics of asphalt binders containing Sasobit®. The findings from laboratory tests and field performance of Sasobit®-modified WMA are also presented. This paper also reviews the life-cycle assessment, energy savings potential and greenhouse gas (GHG) emission reduction potential of WMA containing Sasobit®. The review concludes with a proposal for incorporating aspects related to environmental and energy-efficient asphalt mixes in Superpave™ mix design method. © 2012 Elsevier Ltd. All rights reserved.
