Abstract

The research on the meso-structure of asphalt mixture helps to describe the anti-slide structure and itsevolution more comprehensively and accurately and solve the prominent problem of how to design durable and structure-rich asphalt-layer material in lack of high-quality anti-slide stone material.In this paper,four kinds of denseskeleton asphalt mixtures GAC-13 with non-continuous gradation are designed,and a test device for rub evaluationis developed to simulate the traffic load and environment.Then,by analyzing the specimens in different rub stageswith high-accuracy industry CT scan,a method,which adopts the affecting-zone depth and the decay rate to evaluatethe anti-slide properties of meso-structure of asphalt mixture,is put forward.The results show that GAC-13 with acomplete granular gap of 2.36mm helps to obtain more ideal anti-slide structure.
