Abstract: The article describes the modification of petroleum bitumen with elastomers of different chemical nature and molecular weight. The effectiveness and expediency of such a modification is shown.The objects of research in the work were the following brands of oil bitumen: BN-70/30 and BND-90/130. The following modifiers were used: butyl rubber (BK-1675), liquid thiocol - a condensation product of aliphatic dihalo derivatives with sodium polysulfide, rubber crumb.Shown undoubted efficiency and the prospect of improving the technological and operational properties of bitumen systems by modifying the latter with selected polymers. In addition, this modification is economically feasible due to the low cost of the selected modifiers and their presence in the range of enterprises of the domestic chemical industry.
