重载交通钢桥面铺装MMA耐久型防水材料与防排水体系研究

Study on Pavement of MMA Durable Waterproofing Membrane on Steel Bridge Deck of Heavy Load Traffic and the System of Waterproofing and Drainage

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,钢桥面铺装防水体系受力更为不利,对防水结构和材料性能提出了更高要求。本文介绍了适用于重载交通钢桥面铺装的MMA反应型树脂防水材料与体系,结合实际工程进行铺装防排水体系设计,并分析了其性能特征。

In our country, heavy load traffic is the typical characteristic of the use of steel bridge deck pavement. Under heavy load traffic, the waterproofing system of steel bridge deck pavement faces more unfavorable conditions, and higher level of waterproofing structure and material property are required. The article introduces MMA reactive resin waterproofing material and system which are suitable for the deck pavement of high load traffic steel bridge. Combining with practical engineering, waterproofing and drainage system for the pavement is designed and the performance characteristics are analyzed.
