摘要: 结合S120大修工程实际,总结和分析了交叉口沥青路面加铺层车辙、裂缝等病害及其产生原因,同时针对交叉口的运行特点对路面结构进行力学分析;确定旧水泥混凝土路面加铺沥青路面结构的最大剪应力区和抗车辙区,为交叉口路面结构和材料的抗车辙、抗裂设计提供依据.根据力学计算分析结果,提出几点适合交叉口的路面结构组合和材料选择的建议.  

关键词: 沥青路面;交叉口;车辙;力学分析;路面结构

Abstract: The causes of the rutting, cracks and other diseases of intersection asphalt overlays are summarized and analyzed according to the S120maintenance engineering practiee. Meanwhile the mechanical characteristics of the intersection of pavement structure were analyzed regarding  the operating characteristics of intersections. The maximum shear stress area and antirutting area of asphalt overlays were identified on the old cement concrete pavement,which provides the basis for the antirutting, cracking design of intersection pavement structures and materials. Based on the results of the mechanical calculation, several suggestions on the combination of pavement structures and selection of materials for urban road intersections are provided.
