The article presents the results of a study of the wear resistance of cement concrete coatings of highways. The tests were carried out on the passenger module of the universal complex for testing the road surface and car tires KUIDM-2 “Carousel”, built on the territory of the MADI Educational and Scientific Center (MADI ESC). On a circular stand, the real conditions of interaction of a studded tire of a car wheel with a cement concrete surface were modeled. Road pavements were arranged on the track of the universal ring complex in the form of segments-concrete slabs 100 x 120 cm in size and 10 cm thick. The concrete slabs were subjected to repeated abrasion by spiked rubber. Research has made it possible to establish the influence of the nature of crushed stone, its strength and size of fractions on the wear resistance of cement concrete pavements.
