It is commonly recognized that subsurface drainage system can improve pavement performance and extend service life . as an essential part of subsurface drainage system , the layer setting and characteristics of asphalt treated permeable material directly affect the performance of subsurface drainage system , which is lucubrated in this paper . based on the typical semi - rigid pavement without permeable layer , using multilayer elastic system program , rational pavement structure with permeable layer at different locations is first analyzed 本文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,探讨设置排水层的路面结构的一些结构参数适宜的取值范围,并在此基础上运用灰色系统关联分析方法,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。
