Abstract: The composition and properties of high performance materials for steel bridge deck pavement are quite different, the research of perfor-mance of steel deck pavement material is mainly focused on the strength rule and damage behavior of the loading stage, and less research has been done on the deformation recovery characteristics of the material in the unloading phase. To evaluate the deformation recovery capacity of steel deck surfacing material during the unloading phase, repeated creep and step-loading recovery test was proposed to overcome the shortcomings of creep and step-loading recovery test. It was used to measure the internal stress and residual strain at different time of unloading phase of three typical steel bridge deck paving materials including gussasphalt, epoxy asphalt mixture and stone mastic asphalt. According to the definition of recovery modulus, the recovery modulus at three different creep stress levels was calculated, and the drive deformation recovery ability of the three materials was evaluated in turn. At the same time, based on the viscoelastic theory, the fitting parameters of creep flexibility were determined, and the strain recovery rate of three materials at different intervals were calculated, in order to evaluating the rate of deformation recovery. The results show that the recovery modulus of the materials in a non-destructive state are different from the internal stress, and do not change with the size of the creep load. The epoxy asphalt mixture has the largest recovery modulus, which is about 7 times and 4 times that of the stone mastic asphalt and gussasphalt, and the drive deformation recovery ability of epoxy asphalt mixture is better than gussasphalt and stone mastic asphalt. But at the same interval, the strain recovery rate of gussasphalt is the fastest, and can reach 82% within 3.6 s.
