The practice of operating highways in the Republic of Kazakhstan shows that the durability of asphalt concrete pavements on them is much lower than the standard terms. Therefore, the maintenance of highways in a condition that meets the requirements of traffic flows is impossible without the use of new, progressive materials and technologies. The main factor affecting a sharp decrease in the service life of road surfaces is the use of lowquality bitumen in asphalt-concrete mixtures as a binder, since microcracks develop mainly in its film. The article deals with artificially synthesized bitumens of the Aktau bitumen plant: The following indicators of petroleum bitumen were studied: penetration, extensibility properties, brittleness temperature, softening and ignition temperature. It has been proven that the results obtained correspond to the technical specifications.
