Abstract:

To investigate the fatigue damage of epoxy asphalt pavement(EAP)under a heavy load and and temperature load, the load-figure of the heavy load on the steel bridge deck pavement(SBDP)was simulated first, and the temperature distribution of SBDP during the temperature-fall period in winter was also calculated. Secondly, the moving heavy load coupled with the most unfavorable temperature load was applied to the SBDP, and the tensile stress on the top of SBDP was calculated. Finally, the fatigue damage of EAP was evaluated considering the extreme situation of heavily overloaded and severe environments. The results show that both the heavy load and the temperature load during the temperature-fall period can increase the tensile stress on the top of SBDP significantly. In the extreme situation of heavily overloaded and severe environments, a fatigue crack is easily generated, and thus the SBDP should avoid the coupling effects of the heavy load and the temperature load in winter.
