国内外沥青路面设计方法分析

基于国内外沥青路面现有设计体系,介绍了经验法、力学-经验法、基于性能设计法三大类别,并针对其代表性的设计方法的特点进行了评析;结合我国沥青路面结构设计体系,指出我国设计体系中存在的设计指标、路面材料设计参数、交通荷载等方面存在缺陷,并提出相应的建议。

Based on current design of asphalt pavement both home and abroad, the paper has made introduction to three means of design, namely empirical method, stress empirical method and property-centered method. Moreover, it has made comments on certain representative features of designs. Taking strueture design of asphalt pavement in China into account, the paper presents some demerits in design target, parameter of pavement materials, traffic capacity and the like and finally proposes solutions to such problems.
