基于均匀设计沥青路面抗车辙分析

车辙是沥青路面主要破坏形式之一.研究表明传统的线弹性层状体系可以作为模拟车辙的分析模型.选作沥青基层顶层压应变作为力学响应指标.采用均匀分析方法,合理设计计算次数,有效地获得力学响应,分析层厚和模量对沥青路面抗车辙能力的影响.为提高沥青路面的抗车辙能力提供参考.

Rutting Analysis of Asphalt Pavement Using Uniform Design

Rutting is a major distress form found in asphalt pavements. Past research has shown that conventional elastic-linear model can be applied for rutting analysis of asphalt pavement. The rutting resistance of the pavement system is evaluated through the maximum compress strain transmitted to the top of the sub-grade layer.The simulations are conducted under a parametric study to investigate the beneficial effects of the thickness and the module to the rutting criteria based on uniform design. It is another approach to improve the rutting assistance of the asphalt pavement.
