The article presents the results of secondary polyethylene modification of oil asphalt containing 2.0–2.8% of rubber crumbs. It is shown that at an optimal concentration of black oil M-40 in the content of bitumen composition with an increase in the amount of the introduced plasticizer – secondary polyethylene – from 1.4 to 4.0 mass %, the softening point of the final product varies from 46 to 80⁰C, and the extensibility index – from 4 to 13 cm.
