摘要
半刚性基层沥青路面已成为我国高等级公路和城市道路的主要路面结构形式。通过对目前现行沥青路面设计规范的研究,从轴载换算、设计参数、设计指标三个方面进行分析,对半刚性基层沥青路面设计方法存在问题进行探讨,使半刚性基层沥青路面的设计规范更加完善、合理。
The asphalt pavement with semi - rigid base is the main form of pavement structure in highgrade highway and city road in China.The paper researched the present design specifications of asphalt pavement, analyzed the problems about axle - load exchange,design parameter and design index,discussed on the existing problems of design method of asphalt pavement with semi—rigid base to make the design specifications more perfect and reasonable.
