Analysis of Superpave mix design for asphalt mixture and some experimental research results

Abstract

Superpave is one of the outstanding products of the Strategic Highway Research Program (SHRP) in the world. The Superpave mix design procedure involves selecting PG bitumen and aggregate materials to design the asphalt mixture, meeting the requirements on the basis of traffic speed and traffic level, to prevent pavement damage such as fatigue cracking, thermal cracking, permanent deformation (rutting) during operation. This paper analyses the Superpave mix design for asphalt mixture and presents some experimental research results in laboratory in Vietnam.
