旧水泥混凝土路面罩面工程中调平层厚度确定方法研究

Study of Design Method for Asphalt Mixed Layer Thickness in Cement Concrete Pavement Overlay

我国水泥混凝土路面在公路建设中所占的比重越来越大 ,但其在使用过程中出现的修复困难一直是一个技术难点。如何尽快地恢复旧水泥混凝土路面的使用性能并降低工程造价 ,是目前各地区正在研究的课题。结合湖南省长沙至永安高速公路改造工程对加铺层设计进行了分析研究 。

cement concrete pavement is widely adopted with the development of the economy and road, but its rehabilitation is frequenly a problem during its service . How to revive the cement concrete pavement's performance as soon as possible and reduce project cost is the target of research at present. The authors have analysed thickness design factors of asphalt mixed layer in Changsha to Yongan highway asphalt overlay and summed up the design method.
