沥青稳定碎石排水层的设计

Design of asphalt treated permeable layer

以高等级公路沥青路面的典型结构形式作为未设排水层的路面结构原型,通过不同的设置层位分析对排水层的回弹模量和厚度的要求,探讨设置排水层路面结构的一些结构参数适宜的取值范围,对不同设置层位的路面结构的技术指标进行比较分析,得出较优的层位设置方案。

This paper uses the typical architecture of asphalt pavement in highroad that does not set permeable layer as the highway architecture prototype, bases on the requirements of resilient modulus and thickness in permeable layer in different layer setting analysis, discusses the rational span of structure parameter in pavement architecture setting asphalt pavement. Based on it, the paper compares performance indexes, and gets the prior layer setting.
