Abstract: The research of steel deck Gussasphalt Concrete (GA) temperature characteristics of pavement structure, construction of asphalt rheological parameters and the establishment of the steel box girder finite element transient heat transfer model of sub model technology, analysis of the most unfavorable under the temperature ｌｏａｄ loading layer on the stress distribution of steel box beam, calculates the temperature change characteristic, the influence of different the wind speed on the temperature field of casting steel bridge. The calculation results show that pouring asphalt after pouring the edge of the Von Mises shows the maximum stress, vertical stress mainly acts on the bridge deck, and the diaphragm is mainly responsible for the transverse stress, and with the increase of wind speed, the cooling rate of asphalt mixture increases significantly, when the wind speed is 1m/s the pouring type asphalt cooling speed is relatively slow, wind speed 3m/s when cooling is obviously improved.
