车辙是高温地区沥青路面的主要病害之一。处理车辙一般采用铣刨后重新摊铺抗车辙能力强的沥青混凝土的处理方案。为尽可能利用旧路面的使用价值,尽量减少车辙的铣刨深度,提高沥青混凝土的高温模量显得尤为重要。文章介绍了高模量沥青混凝土在京珠高速公路粤境南段车辙处理中的应用情况。
Rutting is one of the main diseases of asphalt pavement in high temperature areas. Rutting generally used after milling to re-paving the ability of rutting asphalt concrete treatment program. In order to make full use of the use value of the old pavement, it is very important to reduce the depth of rut milling as much as possible to improve the high temperature modulus of asphalt concrete. This paper introduces the application of high modulus asphalt concrete in the rutting treatment of the southern section of Beijing-Zhuhai Expressway.
