Abstract:The objective of this study is to review Superpave Hot Mix asphalt used by other state DOTs and make recommendation to Idaho Transportation Department (ITD) in using this product in its roadways and in particular in low-traffic roadways. Based on the literature review, it is concluded that Superpave mix design provides better performance for roadways that experience heavy to medium traffic volumes. For low-traffic roadways, Superpave, Marshall, and Hveem-designed mixes perform about the same. Considering the unit price, it appears that there are no significant differences among the three mix-design methods.
