城市化特重交通地区旧水泥混凝土路面沥青罩面结构设计

Structure Design of Asphalt Concrete Overlays on Old Concrete Pavements of Urbanization Special Heavy Traffic Area

通过对旧路路面使用状况的调查、检测,分析路面病害产生的原因,据此选取旧路路面结构设计参数。结合道路交通量大和城市功能等特点,经分析和力学计算提出沥青罩面结构设计方案,并对旧路路面病害处理提出相关意见,充分体现了"人文、环保、高效"的大修理念。

Causes of pavement damage are analyzed by investigating and testing the using condition of cement concrete pavement,and the design parameters of cement concrete pavement structure are selected.Combined with the characteristics of urbanization special heavy traffic,the design scheme of asphalt overlay structure and related opinions for treating the pavement disease of old road are put forward based on the analysis and mechanics calculation,which reflects the repair idea of ＂humanity,environmental protection and efficiency＂.
