Analysis of the Possibility of Using Petroleum Asphaltites in the Production of Carbon Fibers for Modification of Road Surfaces

Objective: to explore the potential use of asphalts in the production of carbon fibers, which can be used as dispersed reinforcement additives that improve the physical and mechanical properties of asphalt concrete. Methods: the study employs densimetric, microscopic, and group chemical and elemental analysis methods. Results: a comparative analysis of the physical and mechanical properties and chemical composition of natural and petroleum asphalt samples was performed. Graphs were presented showing the changes in the softening temperature of asphalt depending on the deasphaltization conditions, the changes in the yield of asphalt depending on the process temperature, and the changes in the softening temperature of pitch depending on the temperature and duration of heat treatment. Practical significance: asphaltites are used in the modification of bituminous binders, drilling fluids, the production of adhesives, thermal insulation, and many other industries, and are also of interest for obtaining carbon materials as modifying additives in asphalt concretes.
