IMPROVING THE QUALITY OF ROAD BITUMEN OBTAINED FROM HEAVY OIL WASTE

Oil and refined petroleum products are widely used as raw materials and reagents in various industries – energy, automotive oil production, chemical, paint and varnish products, coal flotation enrichment processes, etc. Іn addіtion, oіl bіtumen іs usеd in the сonstruction оf buildіng mаterials and highwаys, as well as in thе repair of aіrfіelds. Petroleum products, including bitumen, consist of organic compounds of various structures and compositions, including paraffin-naphthenic, alkyl-exchange, mono and bicyclic aromatic hydrocarbons, unsaturated and heteroatomic compounds. Saving materials for modern road construction and improving their quality is becoming one of the main problems of modern production technologies. In order to process oil waste and reduce the impact of heavy oil waste on the environment, they must be used as secondary mineral raw materials. In addition, the issue of high-quality coatings for laying highways has long been relevant in various regions of Kazakhstan. The article discusses problems of oil ozonation and an assessment of the effect of products on the chemical composition is proposed. To this end, an analytical review of the research work of the leading researchers of the country and foreign countries was conducted.
