Petroleum road bitumen modified by waste of petrochemical industry

Abstract

We conducted studies on modification of petroleum bitumen with low a molecular weight polyethylene (LMPE) and residue of the heavier cut of pyrolysis gas oil (residue of PGO) of production plant «Polymir» of JSC «Naftan» to improve the quality indicators of the produced road binder. We measured physical and mechanical properties of asphalt mixture. It was found that adding of polymer- aromatic binder to the resulting asphalt concrete improves its physical and mechanical characteristics. The use of waste of petrochemical industry reduces cost of bitumen in comparison with its analogues.
