Xihoumen Bridge is a separated twin steel box girder suspension bridge with a main span 1 650 m and the steel deck of the Bridge is surfaced by the epoxy asphalt. In accordance with the characteristics of the epoxy asphalt mixture and the construction requirements for surfacing of the deck, the construction technology for the surfacing of the deck are described from several aspects of the raw materials, mix proportioning, production, transportation and surfacing. In the light of the unfavorable factors that surfacing length is long, the wind is strong at the deck level and the prevention of foreign matters and water is difficult, the purposeful quality control measures are formulated. The sampling inspection of the deck surfacing shows that the effect of the surfacing is sound.
