Abstract: The study of the effect of raw material components on the properties of bitumen is of scientific and practical importance, as well as one of the current issues. The study of a three-component system (asphaltene, resin, oil) showed that the penetration rate of bitumen oil increases with increasing oil content: asphaltene. However, the cost of penetration does not depend entirely on the amount of resin. Oil: Decreasing the ratio of asphaltene leads to a decrease in the softening temperature of bitumen. The softening temperature of bitumens is not significantly affected by the amount of resin in them. Oil in bitumen: an increase in the proportion of asphaltene results in a decrease in its brittleness temperature. Depending on the nature of the raw material, the quality of bitumen depends on the amount of fat components in the raw material, especially the softening temperature - the change in penetration dependence, as well as the penetration rate and ductility during oxidation of the same oil tar at the same softening temperature. Thus, in order to obtain bitumen for any purpose on the basis of oxidation of heavy oil residues, the nature of the primary oil, the softening temperature of the raw material, the amount of oil and paraffin compounds in it must be taken into account.
Key words: raw material, bitumen, asphalt, resin, softening temperature, penetration, Viscosity, acidification.
