The process of inhomogeneous surface abrasion of concretes of different composition is modeled, taling account of the structure of the material. Based on the experimental studies, the choice of structural levels of the mechanism of wear is substantiated. To analyze the process of shape changing of the surface abrasion, the mathematical tools of mechanics of contact interaction are used. The criteria for the degree of wear are examined; recommendations for the preparation of wear-resistant concrete tracks are given.
