【 摘 要 】

The studies of paving bitumen chemical composition and physicochemical properties produced by compoundingdeeply oxidized bitumen, tar and vacuum gas-oil of different hydrocarbon composition are carried out.The bitumen is marked to have the optimal complex of properties if the best chemical group composition of three main elementsbitumen binding agents – oils, resins and asphaltenes - is formed. That provides the best structure of bitumen oildisperse system. The object of the research is the selection of compounded paving bitumen chemical group composition that provides the formation of bitumen nanodisperse system as «sol-gel» which quality metrics match the requirements of the new State Standard 33133-2014 «Petroleum paving viscous bitumen».
