随着高等级公路对路面质量要求的提高,桥面铺装的质量要求也相应提高。在桥梁的正常使用期内需经常对面层进行维修或翻新,为保证在面层维修或翻新施工中不对桥梁造成损坏,有必要设置桥面防水层。文章主要从聚合物改性乳化沥青的概述、乳化沥青改性剂的选择、水泥砼桥面防水层的施工质量要求、桥面防水涂料防水层的施工及施工注意事项这几个方面进行阐述,以供参考。
With the improvement of pavement quality requirements of high-grade highways, the quality requirements of bridge deck pavement are correspondingly raised. In the normal use of the bridge during the regular repair or renovation of the surface layer, in order to ensure the surface repair or renovation of the bridge without damage, it is necessary to set the bridge deck. The article mainly elaborates from the aspects of the overview of polymer modified emulsified asphalt, the selection of emulsified asphalt modifier, the construction quality requirements of the waterproofing layer of cement concrete bridge deck, the construction and construction precautions of the waterproof coating of bridge deck waterproofing, for reference.
