摘　　要：鄂咸高速道路沿线常用集料稀缺,安山岩储量丰富,但采用安山岩及常规沥青成型的混合料却存在着高温稳定性及水稳定性能方面的不足.在传统规范测量方法的基础上,采用AIMS集料表观特性分析发现,安山岩集料表面纹理指数较低.针对安山岩表面纹理不足,提出一级颚破、调整关键参数后的二级反击破和三级冲击破的集料破碎加工系统,成功将安山岩应用于沥青路面下面层.Aggregates commonly used along E-Xian expressway are scarce,and andesite reserves are abundant.However,the mixture formed by andesite and conventional asphalt has shortcomings in high temperature stability and water stability.On the basis of the traditional standard measurement method,it is found that the surface texture index of andesite aggregate is low by analyzing the apparent characteristics of AIMS aggregate.In view of the insufficient surface texture of andesite,the aggregate crushing processing system of primary jaw crushing,secondary impact crushing and tertiary impact crushing after adjusting key parameters is proposed,and andesite is successfully applied to the lower layer of asphalt pavement.
