FIELD: petroleum chemistry.
SUBSTANCE: invention relates to petrochemistry, specifically to modification of bitumen binder polymers, and can be used in producing asphalt concrete, waterproofing coatings and mastic for construction works. Disclosed is a concentrate of polymer-bitumen binder and is achieved in a concentrate of polymer modified asphalt binder, having a dry granular form and containing components taken in mass. %: thermoplastic elastomer in amount of 10–50; a plastification component in amount of 10–50; road bitumen in amount of 10–50; stabilizing additive in amount of 0–50; mineral powder in amount of 0–10.
EFFECT: technical result consists in improved performance characteristics of concentrate.
