坑槽是沥青路面的典型病害,严重影响路面的平整度和行车的舒适性.若不及时修补,在交通荷载和水的综合作用下.破坏会较快发展,造成养护费用的增加并严重危及驾乘人员的安全。由于其安全隐患大,通常在高速公路的养护管理中明确提出了“坑槽不过夜”的养护要求。本文根据沥青路面施工过程中路面病害出现坑槽的现象进行分析,针对工程施工中的整体施工情况,提出了一些改善沥青路面沟槽破坏的施工工艺修补方法。
The pit is a typical disease of asphalt pavement, seriously affecting the smoothness of the pavement and the driving comfort.If not repaired in time, under the combined action of traffic load and water, the damage will develop rapidly, resulting in the increase of maintenance cost and seriously endangering Driver’s safety. Because of its security risks, it is usually stated clearly in the maintenance and management of the expressway that “the pit does not stay overnight”. Based on the analysis of the phenomenon of pits in the road surface during the construction of asphalt pavement, some repairing methods of construction technology to improve the damage of the pavement of asphalt pavement are put forward in view of the overall construction in the construction.
