Effect of Group Chemical Composition of a Mixture of West Siberian Oils on Road Asphalt Quality

The group chemical composition of oil fractions refined at Kinef Ltd. is shown to change with time. The oxidation rate and penetration index of asphalt obtained from heavy residual increase as the penetration increases. The extensibility of road asphalt decreases markedly as the paraffin content increases. Road asphalt meeting PNST 1-2012 specifications was produced by compounding asphalts oxidized to different degrees.
