Abstract

The work presents results of the experimental study of dynamic compression of various modifications of bitumen: bitumen 40/60, polymer-bitumen binder and rubber bitumen. The tests were carried out using the Kolsky method. The tests were conducted for the sample temperature of -15 and 20°C. It is shown that polymer modifier and rubber additives have a significant influence on the carrying capacity of the bitumen samples at slow loading, but they do not provide significant advantages in the dynamic tests. Strain rate dependence of maximum compressive stress was obtained for the bitumens. It is shown that this dependence can be predicted by the incubation time criterion. The values of the quasi-static and dynamic strength, characterizing the carrying capacity of bitumen at slow and fast loading, are defined.
