结合作者在非洲某项目的设计经验,介绍当地应用法国标准的沥青路面结构设计体系及其与国内设计体系的对比。以该项目路面设计为例,介绍了法国标准沥青路面设计过程中重车交通量、结构层计算参数取值、路基等级、容许和实际承载力计算、计算风险、路面结构计算和路面结构方案的确定。
Combined with the author’s design experience in a certain project in Africa, this paper introduces the local application of French standard asphalt pavement structure design system and its comparison with the domestic design system. Taking the pavement design of the project as an example, this paper introduces the calculation of the heavy traffic, the calculation parameters of structural layer, the grade of subgrade, the allowable and actual bearing capacity, the calculation of risk, the calculation of pavement structure and the pavement structure scheme in the design of French standard asphalt pavement determine.
