Bending strain density threshold based on elastic damage theory, the j-integral based on elastic plastic fracture mechanics and Cohesion and crack opening displacement based on cohesive zone model were employed to evaluate the fracture resistance of asphalt mixture of SMA-13 AC-13 and CAM in the temperature of 10 5 0 -5 -10 .The results of the study shows when the temperature is below 0 , bending strain density threshold which was used to evaluate crack resistance of asphalt mixture is reasonable, using fracture toughness, cohesion and crack opening displacement index to evaluate the crack resistance property of three kinds of asphalt mixture, the test results are consistent, test results are consistent, namely anti-cracking performance of SMA-13 is optimal, the second is AC-13 and CAM. In addition, the higher temperature is, the better the crack resistance of asphalt mixture.
