A systematic study of the primary tar produced by Shubarkol coal distillation was conducted initially and demonstrated that it can be used to produce road and construction bitumen.Oxidation of coke-chemical tar allowed determining the optimum conditions (temperature and time) of the process, possibility of road and construction bitumen production that meets physical and chemical parameters of grades BND 130/200 and BN 70/30.Oxidation demonstrated that the quantity of total hydrocarbon will be reduced by 19 per cent, and the quantity of asphaltene will be increased by 29.88 per cent.Reduction of hydrocarbons during oxidation demonstrates the formation of tar and asphaltene.Shubarkol coal distillation demonstrated that coke-chemical tar is a potential raw material for bitumen production as a petroleum raw material.
