摘要
柔性基层结构由于基层结构变形大,在重载交通条件下,路面面层短期内在重复荷载作用下易产生疲劳破坏,导致路面结构层的功能丧失。文章通过对大粒径水稳碎石基层施工过程进行全面控制,并结合半刚性基层和柔性基层的优缺点,对改善路面基层结构功能进行探讨。
Because of the large deformation of the soft base structure, the pavement would have fatigue failure under heavy load to make the road losing its funetion Through the overall contrdling to the roadhase construction with the big-particle-diameter water-table gravels, the paper discuases how to improve the roadbase, behavior combing with the advantages and disadvantages of the semi-rigid base and the soft base.
