高等级公路沥青层合理厚度的探讨

A Study on the Reasonable Thickness of High Class Highway Bituminous Pavement

从沥青面层的功能性出发，提出了作为功能层进行结构设计时所要考虑的各项指标，并在此基础上得出了满足功能层需要的最小厚度。

From the performance of bituminous pavement, this paper gives out the index of function layer which must be considered when the constructure design is being made. On the basis, the minimum thickness is presented to meet the function layer need.
