沥青路面核心设计理论的统一

从沥青路面的结构行为方程出发，以上海地区的环境条件为例，按基于性能设计方法优化得出若干路面结构，通过对各路面结构的力学分析和计算，建立沥青层底面拉应变和路基顶面压应变与路面寿命之间的关系，即导出路面现场疲劳方程．将其与国外主流设计方法和我国规范设计方法中采用的疲劳方程进行了对比，结果表明：结构行为分析法与国际现行的设计方法具有内在的一致性，它统一了目前使用的不同类型的设计方程和设计分析理论，实现了路面力学性能与使用性能的统一．

Unification of Core Design Theories for Asphalt Pavements

Based on the asphalt pavement structural behavior equation and a case study of the Shanghai area environmental condition,some pavement structures are obtained according to the(performance)-based design method. Then the relationship between the pavement life and the tensile strain of asphalt layer bottom and the compression strain of subgrade top,namely the pavement field fatigue equations,are established through every pavement structural mechanics analysis and computation.Furthermore,the fatigue equations are compared with that of overseas mainstream design method and China's criterion design method.The results indicate that the pavement structural behavior analytic method is intrinsically uniform with the present international design methods,various design equations and design analysis theories,and pavement mechanics performance and operational performance.
