摘要
为了确定沥青路面合理结构厚度 ,分析研究了沥青路面的半刚性基层厚度或粗粒式沥青混凝土上基层 (即粗粒式沥青混凝土下面层 )厚度与结构疲劳损伤之间的关系 ,选择了两种典型高速公路常用沥青路面结构和以往较成功的路面结构及参数 ,应用SHELL公司Basir3.0程序计算在标准轴载作用下不同路面结构厚度的路表理论弯沉、粗粒式沥青混凝土层底面理论弯拉应力、半刚性基层底面理论弯拉应力和半刚性垫层底面理论弯拉应力 ,计算分析得到路面结构的合理厚度 ;
In order to analyse the relationship between asphalt pavement structure and the failure of structure ,two typical asphalt pavement structures and the parameters are chosen. When asphalt pavement support axial load ,the surface deflection and the theoretical bending stress at bottom of coarse graded bituminous concrete or bottom semi-rigid base or cushion coat are calculated by Basir 3.0 computer program of the SHELL COMPANY. The suitable thickness of asphalt pavement structure is obtained. The evaluation about economy is made.
