干线公路沥青路面典型结构的研究

Investigation of the Typical Structure of Trunk Road Asphalt Pavement

考虑自然环境、交通状况、筑路材料等因素 ,通过路况调查和理论分析 ,筛选出了适宜于河南省干线公路沥青路面典型结构 ,路面典型结构按公路等级推荐 ,共 3类 39种结构 ,而且提出了轴载换算简化方法和季节修正系数、当量轴次增长率的概念。

Through the survey of road condition and theoretical analysis, and according to the environment, traffic conditions, road material and other factors, typical structure of asphalt pavement to fit for trunk road in Henan Province is selected. It is classified into three types of including thirty-nine kinds of structure according to the grade of the road. Besides this, the simplified method for conversion of axle load, the concept of correcting coefficient of season and the increasing rate of equivalent axle load action are also put forward.
