The aim of the study was to experimentally investigate the effect of gamma irradiation in the absorbed dose range of 25-200 kGy on the physicochemical properties of solid waste from oil pipeline transportation. The object of the study was asphaltene-resin-paraffin deposits collected during the cleaning of a main oil pipeline. The following tasks were solved during the work: quantitative determination of changes in the group hydrocarbon composition (oils, paraffins, resins, asphaltenes) by adsorption chromatography; analysis of molecular weight distribution by gel permeation chromatography; assessment of rheological characteristics (melting point, pour point, relative viscosity) and thermal stability by thermogravimetric analysis. It was found that at a dose of 200 kGy, the paraffin content decreases by 1.65 times, while the asphaltene content increases by 1.8 times. The system's polydispersity increases from 6.56 to 10.72, the relative viscosity at 80°C more than doubles, and the coke residue increases from 3.5% to 8.2% by weight. The practical significance of these results lies in substantiating the possibility of using radiation-modified waste as a component of bitumen compositions with increased heat resistance or as a raw material for producing carbon materials. The data obtained can be used in the development of technologies for the disposal of oil waste using ionizing radiation.
