Inquire nowThe Superpave mix design method consists of three basic steps: Aggregate selection. Aggregate is specified in three ways. First, restrictions on aggregate gradation are specified by using gradation specifications. Second, there are physical property requirements on aggregate angularity, flat and elongated particles, and clay content.
