THE IMPACT OF COPOLYMERS SKN-40 AND EPTP-60 ON THE PROPERTIES OF BITUMEN COMPOSITIONS

Rubber mixtures were prepared on the base of butadiene-nitrile rubber SKN-40 (butadiene-nitrile rub-ber), copolymer EPTP-60 (ethylene-propylene triple copolymer), polyvinylchloride and MGF-9 (oligoether acrylate) in the research being conducted. As a result, heat resistance and adhesion were increased. The obtained rubber mixtures were added to the bituminous compositions as a result of which such parameters as penetration and extensibility improved
