【Abstract】 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.更多还原
