- Abstract:
- After cracks appear on steel bridge deck epoxy asphalt concrete pavement, the water would seep in-to cracks which would lead to crack propagation. This paper studied the impact of hydrodynamic pressure on the propagation of steel bridge deck epoxy asphalt concrete pavement crack. ABAQUS was utilized to build a model of steel bridge deck epoxy asphalt concrete pavement with crack. The J integral of pavement crack un-der different temperatures, different pavement crack widths, different pavement crack lengths, different pave-ment crack depths and different number of pavement cracks were calculated. The impact of hydrodynamic pressure on steel bridge deck epoxy asphalt concrete pavement crack propagation was discussed. The results indicated that when hydrodynamic pressure increased, the J integral of pavement crack tip increased, and the effect of hydrodynamic pressure on crack propagation was more obvious. When the temperature was within the range of 0℃ to 30℃, the increase of temperature would lead to the increase of J integral of pavement crack tip and the effect of hydrodynamic pressure on crack propagation would be more obvious. The effect of hydrody-namic pressure on the crack propagation changed obviously under different crack lengths and widths, while the effect of hydrodynamic pressure on the crack propagation changed unobviously under different crack depths and different number of longitudinal crack. Pattern cracking was easy to propagate under the same hydrodynamic pressure.
