浅谈城市道路“白改黑”反射裂缝控制技术

A study on controlling technology of reflection crack during "white to black engineering" of city roads

针对城市道路水泥混凝土路面改造成沥青混凝土路面(俗称"白改黑")的反射裂缝问题,介绍了"白改黑"旧路处理方法及旧路碎石化的沥青层补强设计,分析了不同破损程度的"白改黑"道路改造中反射裂缝的控制技术。

Aiming at the reflection crack problems during city roads cement pavement changing to asphalt concrete pavement, that was ＂white to black engineering＂, the ＂white to black engineering＂ old roads treatment method and old road rubbilizing asphalt reinforcement design was introduced. The reflection crack control technology of different damage degree ＂white to black engineering＂ roads.
