低交通量沥青路面典型路面结构数值分析

Numerical Analysis of Typical Pavement Structure of Low-volume Asphalt Road

针对低交通量沥青路面的主要病害,根据基层材料的变化分两阶段建模,通过仿真分析弯沉值、沥青面层底面和半刚性基层底面的最大主应力等指标,分析路面结构的优缺点,得到推荐的低交通量道路典型沥青路面结构形式。

For low-traffic asphalt pavement of the main road diseases,advantages and disadvantages of the asphalt pavement structure were analyzed based on sub-base material change in the two-stage modeling and simulation analysis of deflection,and the maximum principa stress and other indicators of the urface layer and the semi-rigid bottom of the asphalt pavement.Finally,the paper ended up with recommendations of typical asphalt pavement structure for ilow-volume traffic roads.
