随着我国沥青路面建设事业的快速发展,不同路面结构类型的沥青路面被广泛地应用于全国各地。为合理的选取路面结构设计控制指标,本文从力学响应的角度出发,选取了典型的柔性基层沥青路面、半刚性基层沥青路面和刚性基层沥青路面结构,采用Apbih97软件对面层和基层的应力应变进行了计算,得出了不同结构沥青路面设计的安全控制指标,发现对于3种类型的沥青路面,其水稳碎石或密集配沥青碎石层底的拉应力、拉应变随着轴载水平的增加呈线性增长关系,柔性路面对于超载最为敏感。
With the rapid development of China’s asphalt pavement construction, asphalt pavement of different pavement structure types are widely used all over the country. In order to select the control indexes of pavement structure rationally, this paper chooses the typical flexible asphalt pavement, semi-rigid asphalt pavement and rigid asphalt pavement structure from the perspective of mechanical response. By using Apbih97 software, the stress and strain of the surface layer and grass- The results show that for three types of asphalt pavement, the tensile stress and tensile strain of the water-stabilized gravel or dense graded asphalt pavement are higher than those of the horizontal loading Increasing the relationship between linear growth, flexible pavement is the most sensitive to overload.
