城市道路沥青路面改造设计研究——以西宁市新宁路改造项目为例

Study on Reconstruction Design of Urban Road Asphalt Pavement for Xinning Road in Xining

摘要:

针对城市道路沥青路面长期暴露在外界环境中，在汽车荷载、环境温度及其耦合作用下，路面基层、面层沥青混合料易出现疲劳等破坏，使沥青路面病害增多，病害出现时间提前的现象，通过分析城市道路沥青路面的常见病害类型及其破坏机理，提出了相应的处治措施，并以西宁市新宁路改造项目为例进行实践检验，结果表明改造方案效果良好，可有效减少沥青路面病害或延缓病害的出现时间。

Abstract:

Aiming at the asphalt pavement of urban road exposed to the external environment for a long time, under the action of vehicle load, environmental temperature and coupling, the asphalt mixture of pavement base and surface layer is prone to fatigue and other damages, which makes the asphalt pavement diseases increase and the time of disease in advanced. By analyzing the common disease types and failure mechanism of urban road asphalt pavement, the corresponding treatment measures are put forward. Taking Xining Xinning Road Reconstruction Project as an example, the practice test is carried out. The result shows that the reconstruction scheme effect is good, and can effectively reduce the asphalt pavement diseases or delay the onset of the diseases.
