The article presents the advantages of asphalt concrete mix on foamed bitumen to
ensure high-quality construction. With an increase in the content of rubber crumbs, there is a
decrease in penetration at 25 and 0°C, a slight decrease in extensibility and an increase in the
softening temperature. In this case, the elasticity of the binder’s increases sharply compared to
the original bitumen. Based on the results obtained, the optimal properties have a composition
containing 6% of rubber crumbs, which can be recommended as a binder for the preparation
of asphalt concrete. In our work, the influence of rubber crumb on the properties of bitumen
was studied. For research, we used a rubber crumb produced at the factory "Eco-tire". Using
as a modifier of bitumen rubber crumb obtained from the waste of old tires, allow you to
solve the environmental problem of clogging the environment with waste rubber products.
