Kuzbass is a leader in the field of mining of coal as one of the main materials for industry and civilian use. Its production rate its is constantly increasing, which can not but affect the problem of using secondary material (in particular, rocks that are not used in further construction) that is produced during coal mining. Overburden rocks are often stored in dumps or they are used for filling coal mine roads, although this is the problem. In terms of their physical and chemical composition, the overburden rocks are of low strength, so there is a problem of strengthening this type of material, the solution of which can be found in the processing of rocks used for further construction with modified bitumen. The analysis of the effect of the adhesion ability of construction bitumen and crumb rubber modified bitumen produced according to the technology of stage addition of rubber crumb to bitumen (bitumen modified with crumb rubber by stages) is described in the article. Examples of the adhesion of construction bitumen and bitumen modified with crumb rubber by stages to various rocks are given. The characteristics of the adhesion ability of bitumen modified with crumb rubber by stages are substantiated.
