Feasibility Research on Superpave Gyratory Compactor Method Design Mix of Stone Mastic Asphalt

Abstract:

This paper analyzed the limitation of the stone mastic asphalt (SMA) mixture designing methods in China, then the Superpave Gyratory Compactor(SGC) method for SMA mixture where designing applicable and feasibility was analyzed, and SGC method was introduced to promote the application in SMA mixture design. It is found that the compaction work determined by the SGC design procedure was remarkably increased compared to that by Marshall design when the number of gyrations is 100. It is recommended that the number of gyrations should be decreased instead of 100 when SGC is used to design SMA mixture in China.
