沥青混凝土桥面渗水预防性养护处理

Discussion on Preventive Maintenance Treatment for Water-Seepage of Asphalt Concrete Deck

结合工程实际,介绍了沥青混凝土桥面铺装桥梁上部结构因水产生的早期损害情况,进行在沥青混凝土桥面铺装层上喷涂防水层的预防性试验处理,对沥青混凝土桥面铺状进行预防性养护,改变了传统养护维修的观念,在桥面未出现病害时即对桥面进行一定的养护使其处于较佳的路用性能,延长桥面的使用寿命。

Combining with project practice,this paper introduces the early damage of the superstructure of the asphalt concrete deck pavement caused by water,the preventive test treatment by using water-proof layer on the asphalt concrete deck,the preventive maintenance through paving the asphalt concrete deck,the change of idea of the traditional maintenance that some maintenance job should be done to have the better performance of the road and prolong its service life when the bridge deck does not have the damage.
