混凝土桥面铺装防水粘结层研究

Study on Waterproof Binding Course of Concrete Bridge Deck Pavement

混凝土桥面铺装层破坏已成为影响高速公路使用功能发挥以及诱发交通事故的一大病害,成为当前迫切需要解决的重要问题。究其原因,主要是对桥面铺装防水粘结层的重要性认识不够。本文在对国内防水粘结层设计存在的问题进行整理的基础上对桥面铺装层进行力学分析,研究防水粘结层在桥面铺装中的作用,并对防水粘结层的设置提出了一定的功能要求。

The damage of concrete bridge deck pavement which would impair the function of freeways and cause traffic accidents has become a serious problem needing urgently to cope with.The reason for that is mainly due to lack of knowledge about importance of waterproof binding course of bridge deck pavement.Through mechanical analysis of bridge deck pavement based on defects present in design of the binding course in China,the article explores the role the course plays and sets functional requirements for the course.
