The irregularity of the pavement surface was simulated by using the power spectrum density function, the random load was calculated according to the vehicle vibrating equation, and the dynamic response of the deck pavement under random dynamic load was analyzed by using FEM. The results when considering roughness were compared with those when considering the impact coefficient and static response only. The results indicate that the mid-span of the model is the least favorable load area; the maximum vertical displacement and the maximum transversal tensile stress of pavement are 1.33 times and 1.39 times as much as those when considering only the impact coefficient, respectively. The effects of vehicle speed on the maximum vertical displacement and the maximum transversal tensile stress were studied. This study provides the theoretical basis for the mixture design and structural design of pavement and for requesting a higher quality level in the construction and maintenance of pavement.
