旧水泥混凝土路面的病害及治理措施

旧水泥路补强设计不同于新建路面设计,其设计目的是为满足一定时间内的交通需要,因此旧路补强设计应根据道路等级、交通量、改扩建规划和有经验确定适当的设计基准期。该文以浦星公路(外环线-区界)改建工程为例,阐述水泥路面上加铺沥青面层的设计过程和方法,可供同行借鉴。

Fault of Old Cement Concrete Pavement and Its Treatment Measures

The reinforcing design of old cement road is different from the design of new pavement.Its design aim is to satisfy the traffic demand within a certain time.Therefore,the suitable design reference period should be determined according to the road grade,traffic flow,reconstruction and extension planning,and experience in the reinforcing design of old road.Taking Puxing Highway(Outer Ring Line ~ Area Boundary) Reconstruction Project as an example,the article sets forth the design process and method of cement pavement overlaying asphalt surface,which can be referred for the similar projects.
