摘　　要：针对绿泥石片岩与沥青集料黏附性差导致混合料的水稳定性不佳的问题,论文以武汉至大悟高速公路项目为依托,基于绿泥石片岩集料的特性分析,研究了绿片岩集料、沥青界面黏附机制与分析模型,以及绿泥石片岩沥青混合料的配合比设计方法,同时提出了绿泥石片岩集料沥青混合料的改进措施和评价方法,有效解决了绿泥石片岩集料与沥青黏附性差、混合料水稳定性不足等问题。Aiming at the problem of poor adhesion between chlorite schist and asphalt aggregate resulting in poor water stability of the mixture,based on the Wuhan to Dawu Expressway project,this paper studies the interface adhesion mechanism and analysis model of chlorite schist aggregate and asphalt,as well as the mix ratio design method of chlorite schist asphalt mixture based on the characteristic analysis of chlorite schist aggregate.At the same time,the improvement measures and evaluation methods of chlorite schist aggregate asphalt mixture are put forward,which effectively solve the problems of poor adhesion between chlorite schist aggregate and asphalt and insufficient water stability of the mixture.
