沥青玛碲脂碎石(SM A)混合料主要采用玄武岩、辉绿岩等优质石料,对于优质石料匮乏地区,为降低SM A造价,探索利用成本低廉的花岗岩或石灰岩配置SM A的可行性,具有十分重要的意义。本文选择玄武岩、辉绿岩、花岗岩、石灰岩等4种石料,以SM A沥青混合料抗高温稳定性为切入点,采用规范车辙和多轮车辙仪(RLW T)试验方法,进行对比研究。
Asphalt maressel composites (SM A) mainly use high-quality materials such as basalt and diabase. In order to reduce the cost of SM A and explore the feasibility of SM A using low-cost granite or limestone for high-quality stone-lacking areas, It is of great significance. In this paper, basalt, diabase, granite, limestone and other four kinds of stone materials were chosen to study the anti-high temperature stability of SM A asphalt mixture. The standard rut and RLW T test methods were compared.
