STUDY OF THE GROUP COMPOSITION OF BITUMENS AND ITS POTENTIAL INFLUENCE ON PHYSICAL AND MECHANICAL PROPERTIES AND ENERGY EFFICIENCY

This article discusses bitumen materials as an important material in the energy sector due to its high energy intensity. The influence of the group chemical composition of road bitumen on their physical and mechanical properties during commissioning of production is studied. Particular attention is paid to the relationship between the chemical composition and properties of bitumen, which is important for its processing and use as a raw material for alternative energy sources. The results of a study of the influence of the group composition on the rutting of asphalt concrete, which is one of the main indicators of the performance of asphalt concrete, are also presented. These studies will help to adjust the oxidation process of tar to obtain high-quality bitumen material with specified characteristics that will meet all the requirements of regulatory and technical documentation. The findings of the study highlight the importance of detailed analysis of bitumen to optimize its use, improve energy efficiency and reduce environmental impact. The article aims to broaden the understanding of the role of bitumen in the modern world and its potential in the context of sustainable development. Keywords: resins, oils, asphaltenes, bitumen, chromatography.
