The article describes the reasons, factors and innovations of rubber-bitumen binder modified by the rubber crumb obtained with a two-step technology of its introduction. To analyse the rubber-bitumen binder’s structure, the methods of infrared spectroscopy and atomic-force microscopy have been used. A mechanism changing the rubber crumb surface after thermomechanical modification is described in the paper. The process of temperature resistance and elasticity of rubber-bitumen binders is substantiated. The presence of natural rubber in the binder is described through the analysis of IK spectroscopy images.
