| Abstract: | Stone Matrix Asphalt(SMA), as a new mode and premium mixture, has gained much attention in road design. Recognized for its peculiar structure, the aggregates gradation of SMA mixture was designed by means of Void Design Procedure(VDP) in this paper. Due to both the gap - graded nature of SMA mixes and the relatively large proportion of asphalt cement, the gradation designed by VDP can ensure the formation of a stone framework by creating significant stone - on - stone contact among the coarse aggregate, and the for mation of a thick matrix film by mastic filling this framework. The test result has proven to deliver improved durability and resistance to rutting and fatigue cracking. |
