After the Sutong Bridge was opened to traffic in 2008, as of October 2017, a variety of disease types have appeared in the epoxy asphalt concrete pavement. However, as of now, the durability evaluation of steel bridge deck pavement during the operation period is almost blank. Therefore, the research team investigated and tested the use condition of the epoxy asphalt concrete pavement for steel box girder of Sutong Bridge. The results show that the strengths of different positions in the heavy lane have different degrees of attenuation, and the pavement layer of the uphill section is the most damaged. The crack resistance of the epoxy asphalt mixture is less affected by external conditions. The bending strength of the double-layer beam in the complicated force bridge section and the threat of disease is obviously decreased, and the deformation performance first increases and then decreases. In the single-layer beam, there is a bridge surface pavement with disengaging disease and complicated forces. The low temperature performance of the lower layer of the pavement is not as good as that of the upper layer of the pavement. The epoxy asphalt mixture has good water stability.
