A result of overweight traffic investigation is given in the paper. Based on the result of investigation, the stress and deformation in different position of concrete pavement slab under overweight traffic are calculated by finite element method. The concrete slab early failure mechanics mechanism under overweight traffic action is analyzed. It comes to a conclusion that fatigue life of concrete pavement lab will be reduced greatly under overweight traffic action.
