Design of steel deck pavement of long-span continuous steel box girder bridge

Abstract:

The mechanical properties of the steel deck pavement on Chongqi Bridge were carried out using a three stage mechanical analysis method. Based on the results of the mechanical analysis and the research conclusion of the main steel deck pavement cases, dual layer epoxy concrete steel deck pavement was designed. The pavement performance such as moisture resistance property, high and low temperature property, salt spray resistance property, mechanical property and fatigue property of epoxy asphalt concrete had been researched. The results show that the rich-asphalt epoxy asphalt mixture can satisfy the requirements of Chongqi Bridge deck pavement better than common epoxy asphalt mixture.
