重载交通钢桥面铺装新型结构与材料

New Structure and Material of Steel Deck Pavement of Heavy Traffic

重载交通是我国钢桥面铺装使用的典型特征,重载交通条件下钢桥面铺装受力更为不利,对铺装材料和铺装结构性能提出了更高要求。该文介绍了适用于重载交通钢桥面铺装的反应性树脂混凝土、反应性灌注式混凝土、Bripro防水粘结体系等新型材料及其组成的RIPE铺装结构,并分析了其性能特征。

The heavy traffic is the typical characteristic of using the steel deck pavement in China. It is more disadvantaged for the steel deck pavement stress under the condition of heavy traffic, which puts forward the higher requirement for the pavement material and pavement structure performance.The article introduces the new materials of the reactive resin concrete,reactive poured concrete and Bripro waterproof binding system suitable for the steel deck pavement of heavy traffic as well as the composed RIPE pavement structure,and analyzes its performance characteristics.
