在城市道路白改黑中选择应力吸收层材料的要点探讨

Discussion of Gist to Select Material of Stress Absorbent Bed in Urban Road“Cement-into-Asphalt”Project

白改黑是近年来在城市道路路面改造中常用的一种方案,而应力吸收层是白改黑中一种路面特殊材料,可以有效地延缓和防止反射裂缝,因此常常被认为是白改黑中的一项关键结构。探讨了三种应力吸收层材料的优势要点,对在实际白改黑工程设计中的应力层材料选择具有一定的参考价值。

In recent years, the cement-into-asphalt method is a common scheme in the reconstruction of urban road. The stress absorbent bed is a special pavement material in the cement into asphalt project, which can effectively delay and prevent the reflection crack. Therefore, it is often known as a key structure in the cement into asphalt project. The article discusses the advantages and gist of three stress absorbent beds,which can be referred for the selection of stress absorbent bed in the actual design of cement-into-asphalt projects.
