The aim of this work is to study the possibility of developing oil road bitumen by goudron oxidation of mixed base oils with the softening temperature of 24 °C from the Martyshi and Mangistau deposits using vacuum residue of more than 450 °C of highly resinous oil from the Karazhanbas deposit of the Republic of Kazakhstan as an additive, elemental sulfur modifier and induction moments. Karazhanbas oil has a high content of oil tars (24.18 % wt.) and asphaltenes (4.85 % wt.). The oxidation of goudron and vacuum residue of highly resinous oil was carried out in a bubble reactor when thermostating at 200 - 210 °С, specific air consumption of 1.8 – 2 l/min·kg. The oxidation process of the feedstock was completed when the viscosity of bitumen was reached by the ring-andball method of 32-35 °C. Oil bitumen was obtained with the following technological characteristics: penetration at 25 °C 105 mm, melting point 51 °C, tensibility at 25 °C 67 cm, flash point 230 °C, brittle temperature minus 15 °C.
