环氧沥青混凝土在大跨径悬索桥钢桥面铺装中的应用

Application of Epoxy Asphalt Concrete in Pavement of Long-span Suspension Bridge Steel Deck

对环氧沥青混凝土在武汉阳逻长江大桥钢桥面铺装中的应用进行了分析和总结。首先通过力学分析确定了铺装层结构的厚度及形式,然后通过室内试验评价了环氧沥青混凝土的各项使用性能,并总结了环氧沥青混凝土在施工及养护过程中需特别注意的问题,可为今后大跨径悬索桥的桥面铺装工程提供借鉴。

The application of epoxy asphalt concrete in the steel bridge pavement of Yangluo Yantze River Bridge in Wuhan is summarized in this paper. Through mechanical analysis and test, the thickness and form of pavement structure were determined at first, then the performance of epoxy asphalt concrete was evaluated by the laboratory tests, and the problems should be pay attention in epoxy asphalt concrete construction and maintenance were summarized. The results could provide reference for the deck pavement engineering of long-span suspension bridge in the future.
