城市旧水泥混凝土路面加铺沥青面层裂缝病害探究

旧水泥混凝土路面加铺沥青面层越来越多地出现在城市道路中,加铺路面病害也日益显著。城市道路由于其不同的行车特点以及施工周期,路面的破坏特点、机理与一般的高速公路有一定不同。如何正确掌握裂缝产生原因并制定有效防范措施,是沥青加铺技术控制的重难点。结合武汉市珞狮南路改造旧路加铺施工实践,对上述问题进行简明阐述和总结。

Study on Crack Fault of Urban Old Cement Concrete Pavement Overlaying Asphalt Surface

The asphalt surface overlaying on the old cement concrete pavements are more and more used in the urban roads,and also the faults of the overlaid pavement are increasingly highlighted.The damage characteristics and mechanism of urban road pavement are relatively different from the general expressways because of its different traffic characteristics and construction period.It is more difficult to how correctly master the crack causes and draw up the effective preventive measures for the control of asphalt overlaying technology.The article briefly sets forth and sums up the above problems according to the construction practice of Wuhan City Luoshi(S) Road Reconstruction Old Road Overlaying Project.
