中面层抗高温车辙性能研究

Anti-rut Function of High Temperature in the Middle Course

随着交通荷载的不断增加,沥青路面中面层已经成为主要的承载结构层,同时它也是出现车辙比较严重的结构层。为了满足路面结构的竖向受压,并且起到好的粘结层的作用,同时要求其具有很强的高温抗变形能力,故该层宜采用抗车辙的高模量的改性沥青混合料。

With the continuous inereasing of traffic loading, the middle course of asphalt pavement has become main structure layer supporting traffic loading, which has relatively servere rut for the middle course. In order support the vertical pressure of pavement structure as a good cohere layer with great anti-deformation under high temperature, anti-rut modified asphalt mixture can be used in the middle course.
