FIELD: manufacture of building materials.
SUBSTANCE: bitumen-polymer composition, which can be used in road building to create asphalt-concrete pavements, aerodrome and bridge surfaces, is constituted by divinylstyrene thermoplastic elastomer, 1.0-5.0%, plasticizer, 1.0-20.0%, antioxidant, 0.05-5.0%, and bitumen, the rest. Manufacturing method comprises component mixing stages and conditions of stages.
EFFECT: stabilized physicochemical performance characteristics and shortened manufacture time.
