Abstract

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 at 10 5 0 -5 -10 . Using fracture toughness, cohesion and crack opening displacement index to analyze the crack resistance property of three kinds of asphalt mixture, the test results is that anti-cracking performance of SMA-13 is optimal, the second is AC - 13 and CAM. So, Fracture energy and cohesion model test can reasonably evaluate anti-cracking performance of asphalt mixture.
