摘要针对水泥混凝土路面加铺沥青层存在的反射裂缝问题,探讨了张开型和剪切型等2种类型反射裂缝的形成与扩展机理;分析了改善沥青加铺层性能、设置中间夹层和处治旧路面板等三种类型的反射裂缝防治技术及其特性;结合室内试验和实体工程验证了各种防治技术的使用效果;提出了各种防治技术所适用的反射裂缝类型。 In view of reflection crack problem of asphalt overlay on concrete pavement,the formation and expansion mechanism of open type and shear type reflection cracks are discussed. Three types of reflection crack prevention and treating technology and its features are analyzed, such as improving the performance of asphalt overlay, setting the intermediate sandwich and treating old pavement plate. According to the effect of various kinds of prevention and control technologies by laboratory test and real engineering,applicable types of reflection crack for various technology of prevention and treatment are proposed.
