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-rubber-bitumen binder, having a dry granular form and containing components taken in wt%: thermoplastic elastomer in amount of 10–50; rubber powder of fraction from 0 to 0.63 mm in amount of 10–50; plasticising component 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 of polymer-rubber-bitumen binder.
