FIELD: chemistry.
SUBSTANCE: device for modified bituminous binder manufacture includes a tank with oil heating coils, thermal insulation, galvanized metal sheet lining, a manhole, a modifying components supply unit and a mixer with an electric drive in the form of a vane device in a cylindrical outer casing with bitumen and modifier mixture taking from the upper layers and feeding to the tank bottom, input and output circulation pipes with ball valves heated by thermal oil, bitumen filter, electric pump with an inverter and a passive hydrodynamic dispersant, as well as a dispersant washing unit as part of the washing oil tank and oil pump connected by pipes to the dispersant inlet and outlet via three-way valves, allowing the dispersant to be washed with an oil flow directed oppositely to the flow through the dispersant during bitumen modification cycle.
EFFECT: production of modified bitumen, including polymer-modified, without the use of plasticisers, and energy-efficient obtaining of uniform distribution of the modifying component or optimal continuous spatial structure of thermoplastic elastomers in the entire volume of modified bitumen.
