许多桥梁的沥青混凝土铺装层不同程度地出现车辙、推移、开裂、坑槽、脱离等早期破坏现象,直接影响车辆的正常运行和桥梁外观,导致桥面维修期大大提前。公路桥面水泥砼铺装层施工,是桥梁水泥砼铺装的最后关键工序,铺装层的质量优劣直接关系到其上沥青砼铺装层的质量优劣和桥梁的使用性能。 The asphalt concrete pavement of many bridges shows the early destruction of rutting, displacement, cracking, potholes and detachment to varying degrees, which directly affects the normal operation of the vehicle and the appearance of the bridge, resulting in the bridge maintenance period being greatly advanced. The construction of highway bridge deck cement concrete pavement is the final key process of bridge cement concrete pavement. The quality of pavement layer is directly related to the quality of its asphalt pavement layer and the performance of the bridge.
