“…In world practice, two main technologies for modifying bitumen with rubber crumb are considered: relatively low (160 ... 200°C) process temperature technologies without any special requirements for mixing facilities [1][2][3][4][5][6][7][8][9] -the Asphalt Rubber method and increased (200 ... 260°C) process temperature technology using special mixers -the Terminal Blended method [10][11][12]. Combined methods are also proposed when the process temperature corresponds to the interval characteristic of the Terminal Blended method, and the use of high-speed mixers is not required.…”

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.

“…There are various technologies for bitumen modification in the world practice: Asphalt Rubber [1][2][3][4][5][6][7][8][9], Terminal Blended [10] and their combinations [11,12]. The rotational method for determining their viscosity is the most common.…”

Abstract. The continuing growth in mineral extraction entails an increase in industrial waste, which in turn has a negative impact on the environment. Rubber-tired vehicles, in which the tires wear colossally, is mainly used as a transport for loading, unloading, transportation and other types of work in the extraction of solid minerals. The used tires are not disposed in any way, but are stored in special areas where harmful toxic substances are emitted under the influence of ultraviolet rays. Therefore, a decision was made to find a method for utilization and rational use of industrial waste in the road construction sector.The operating temperature of composite rubber-bituminous binders based on rubber crumb from the used automobile tires is estimated in this paper, which is necessary for assigning technological parameters of production and laying of asphalt-concrete mixtures produced on their basis. It is established that composite rubber-bituminous binders based on rubber chips from the used automobile tires, produced according to the twostage technology, have the same viscosity as the original petroleum bitumen, at a temperature increased by 20°C.
