A laboratory ice-breaking test was employed for an asphalt pavement with different dosage of rubber crumbs to study the ice-breaking effects by a self-developed road ice-breaking simulating tester. The mesoscopic model of rubber crumbs asphalt pavement structure with 2mm ice layer was established using the discrete element method, and the mesoscopic responses of rubber crumbs asphalt pavement structure were simulated under the standard axle loading. The results indicate that the weighted average rebound amounts of BPN with 3% rubber crumbs increase by 11.45% and 1.46%, respectively, compared with that of 2% and 4% rubber crumbs. The weighted average rebound rates of BPN with 3% rubber crumbs increase by 11.22% and 3.06%, respectively, compared with that of 2% and 4% rubber crumbs. For 3% rubber crumbs, the maximum contact forces in this pavement structure are the biggest which are 2.705×103N before loading and 2.706×103N after loading, and its strain energy is 1.34 times that of 2% rubber crumbs, 1.25 times that of 4% rubber crumbs. In addition, the results of numerical simulation are consistent with the results laboratory test.
