Abstract. The results of studies of oxidized road bitumen according to GOST 33133 and GOST R 58400.1 obtained from tars of JSC «Syzran Refinery» of different viscosities of 100, 150 and 200 seconds under conditions of deepening oil refining achieved at the enterprise for the period 2019-2022 are presented. It is shown that the production of road bitumen with the required level of properties under conditions of weighting of petroleum raw materials is possible with the implementation of measures that help compensate for the shortage of paraffin-naphthenic and aromatic compounds, however, the quality reserve of the resulting binders decreases.
It has been established that the involvement of light oils of the Orenburg deposits type and, especially, gas condensates in the processing of West Siberian fields into oil at AVT leads to a deterioration in the low-temperature properties of both standard oxidized road bitumen produced according to GOST 33133 (tensility at 0 оC, brittleness temperature) and new bitumen materials according to GOST R 58400.1-2019.
