摘要
温度荷载是导致半刚性基层沥青路面反射裂缝形成和扩展的主要因素。通过对反射裂缝在温度荷载作用下的参数进行有限元分析,掌握反射裂缝的扩展机理;通过从理论上对加筋沥青路面基层进行分析,并进行加筋沥青路面阻裂效果分析,从而指导工程实践。研究表明,采用加筋技术阻止反射裂缝的措施是非常有效的。
Temperature load is the main factors leading to reflective crack formation and expansion of. Through the finite element analysis of reflection cracks of the temperature load, the paper grasped the expansion of cracks from the theory of reinforced asphalt pavement to guide engineering practice. The research shows that using the technology of reinforced measures to prevent reflective cracking is very effective.
