The article presents the results of studies of the interaction of organic binders with slag materials in asphalt concrete mixtures. It is determined that slag crushed stone treated with a binder is a high-quality material that is widely used for the construction of coatings and bases. The processing of crushed stone with a binder ensures that it is completely covered with a film of a given thickness. The thickness of the film is interrelated with both the viscosity of the binder and the properties of slag rubble. The greater the viscosity of the binder, the thinner the film on the grains. With a decrease in the grain size, the film thickness also decreases, with an increase in the grain roughness, the thickness of the binder film increases. During compaction, coagulation bonds are formed due to the convergence of the grains coated with the binder, which have sufficient strength and high water resistance. Compared with the method of impregnation and displacement on the road, this method saves the binder.
