摘要
基于城市道路的交通运行特征,分析了城市道路沥青路面永久变形产生的机理。结合《城镇道路路面设计规范》(CJJ169-2012),计算了沥青面层剪应力,从城市道路设计的角度为控制沥青面层永久变形提供了建议。
Based on the traffic operation features of urban road, the article analyzes the mechanism causing the permanent deformation of urban road asphalt pavement. According to Town Road Pavement Design Standard(CJJ 169-2012), the article calculates the shear stress of asphalt pavement, and puts forward the proposal for controlling the permanent deformation of asphalt pavement from the angle of urban road design.
