摘要
通过分析半刚性基层路面和永久性路面的设计理念、结构特点、结构层功能和材料性质,并考虑中国国情,可总结出半刚性基层路面和永久性路面两种路面结构型式的适用条件:半刚性基层路面较适合少雨地区,季节、昼夜温差变化较小地区,以及小交通量、以客运为主的轻载道路;永久性路面对大交通量、以货运为主的重载交通以及多雨地区具有较好的适用性。
Through analysis design idea, characteristics of structure, function of pavement layers and nature of materials of semi-rigid pavement and perpetual pavement and combining with Chinese reality, the application conditions for perpetual pavement and semi-rigid pavement are put forward. The result is the semi-rigid pavement should be applied in the area with no frequent rain, small temperature variations or highway with low traffic and light load, and the perpetual pavement is fit for the expressway with high traffic, heavy load or area with frequent rain variations.
