摘　　要：防水层作为桥面铺装施工中的重要组成部分,其施工质量直接影响防水效果,进而影响桥梁的使用寿命。不同的防水材料由于各自的特性不同,需制定与之适应的施工方式,并结合工程实际进行规划。结合成渝高速入城段改造项目,对采用双组份聚天门冬氨酸酯聚脲防水涂料作为防水材料的桥面铺装防水层施工方法进行介绍。As an important part of bridge deck pavement construction,waterproof layer constructs a quality directly affects the waterproof effect,and then affects the service life of the bridge.Because different waterproofing materials have different characteristics,it is necessary to formulate appropriate construction methods and plan them according to the actual project.Combined with the reconstruction project of Chengdu-Chongqing high-speed urban section,the construction method of waterproofing layer for bridge deck pavement using two-component polyaspartic ester polyurea waterproofing coating as waterproofing material is introduced,which provides reference for the application of this material in the field of road and bridge waterproofing.
