摘　　要：结合北京市多条沥青混凝土旧路路面病害,对道路病害的成因与治理进行了深入的研究。阐述了沥青混凝土路面病害调查的程序,重点分析了裂缝类病害形成的原因,并对个别病害有效而合理的治理措施进行了论述。最后运用有限元软件进行了模拟分析,说明了治理措施的可行性。The causes and managements are studied deeply according to the pavement diseases of several old asphalt concrete roads in Beijing. The main procedure about the disease investigation of old asphalt concrete pavement is represented and the causes of the crack diseases are analyzed. Furthermore, the effective and rational management measures to some kinds of diseases are expounded. At last, the forming mechanism of reflection crack is simulated with the finite element analyzing software, it illustrates that the management is feasible.
