水泥砼路加铺沥青混凝土面层的探析

A Study on the Cement Concrete Road with Asphalt Concrete Surface Layer

在旧水泥混凝土路面加铺沥青面层是目前比较普遍的城市道路改造方法,但由于其基层的特殊性,出现反射性裂缝在所难免。文章对基层的修复处理、加铺沥青面层施工的要点以及抑制和延缓反射性裂缝产生的若干方案进行了比较分析,以期对提高加铺工程质量、减少道路病害提供参考。

It is a widely-used way for cities to put an asphalt concrete pavement layer on old cement concrete roads.But due to the unique traits of its foundation,it is inevitable to crack reflectively.This paper conducts a comprehensive demonstration on the repair of foundation,key points on asphalt implementation and different programs on inhibiting and delaying reflective crackings,which has a guide role on enhancing project quality and assuaging road hazards.
