摘　　要：反射裂缝是半刚性基层沥青路面的主要病害之一,它不仅降低路面的使用性能,影响行车舒适性,而且也影响到路基的强度和稳定性。笔者在介绍反射裂缝概念基础上,简要叙述了反射裂缝形成机理及扩展规律的几种理论。针对裂缝形成机理,笔者总结出几种防治反射裂峰的措施。The reflection crack is one of main diseases at asphalt pavement of semi - rigid base ,which not only lowers the service performance of pavement and affects the comfort during driving, but also has impact on strength and stability of subgrade. The author introduces the conception of reflection crack,on this basis briefly narrates the mechanism of reflection crack forming and its extension law. Aiming at mechanism of crack forming, author sums up some measures for prevention - treatment of the crack.
