FIELD: chemistry.
SUBSTANCE: method comprises sequential administration of bitumen under agitation at 150-160°C plasticiser, which is used as tall oil, a polymer in the form of a block copolymer of butadiene and styrene, styrene-butadiene-styrene, stearic acid, epoxy resin and mixing of all the components for 1.5 hours at a temperature of 150-160°C to complete dissolution, then the resulting mixture is introduced polyethylenepolyamine and stirred for 10-15 min at a temperature of 150-160°C.
EFFECT: improving homogeneity of polymer-bitumen, its physical-mechanical characteristics, reduction of time and the cooking temperature of polymer-asphalt astringent and development stage process it is received.
