宽幅桥面在施工时因其桥面平整度不易控制,导致后期沥青铺装层在桥面凹陷处产生唧浆、坑槽等病害,且病害经常规处治后往往反复出现。本文结合宁波地区高速公路此类病害处治经验,系统的进行了相关研究,并针对性地提出了一种较为有效的处治方法,即两层SMA沥青混凝土路面结构结合雷诺锋预防性养护工艺的处治方法,以期与同行共同探讨和借鉴。 Wide bridge deck is not easy to control due to the flatness of bridge deck during construction. As a result, later asphalt pavement layer produces slurry, pit and other diseases in the depression of bridge deck, and the disease often appears repeatedly after treatment. In this paper, the experience of the treatment of such diseases in Ningbo Expressway was systematically studied, and a more effective method of treatment was put forward, that is, the treatment of two-layer SMA asphalt pavement structure combined with the preventive maintenance process of Renault front Methods, with the hope to discuss and learn from their peers.
