半刚性基层材料在上海地区道路中的应用

对上海地区半刚性基层应用情况,进行了简要的回顾,并对上海地区较广泛采用的三渣基层应用过程中所暴露出的问题,进行了分析。结合上海周边地区对水泥稳定碎石技术应用情况,进行了分析。在对两种半刚性基层材料性能分析对比的基础上,结合不同道路建设特点,提出了上海地区在重载道路沥青路面基层和通车时间要求紧的项目中应积极推广水泥稳定碎石基层的建议。

Semirigid Base Course Materials Applied in the Road of Shanghai Area

A brief retrospect is given of the application of semirigid base course in the area of Shanghai, with the analysis of the problem in the lime-flyash concrete base course widely adopted in the area of Shanghai, including the analysis of the application of cement stabilized macadam. Based on analysis and comparison of the material properties for the two semirigid base courses and incorporated with different features of road construction, it is proposed that cement stabilized macadam base course be promoted actively in the area of Shanghai for projects with heavy load asphalt pavement base course and short time for being opened to traffic.
