Abstract: Asphalt concrete in road surfaces is exposed to static and dynamic loads from passing vehicles, the influence of weather factors and, above all, in the climatic conditions of the Donetsk People’s Republic and the Russian Federation, high temperatures, ultraviolet, radiation and infrared irradiation, the action of air oxygen, alternate freezing. thawing, long-term water saturation. In the process of production, thermostating in thermal bins, transportation to the place of laying in pavement layers and under operating conditions in the pavement of a non-rigid road pavement, concrete mixtures and concrete prepared on organic binders are subject to aging. The main external factors that determine the irreversible change in the properties of asphalt concrete are temperature, penetrating radiation, ultraviolet spectrum of the sun, air oxygen, moisture, aggressive chemicals, etc., and internal factors: the structural-rheological type and consistency of oil road bitumen, chemical and mineralogical composition of mineral components asphalt concrete, type of granulometry, structure and texture of concrete [1–16]. This leads to the fact that the service life of the asphalt concrete pavements of the highways of the Donetsk People’s Republic is only 5–7 years instead of 12 before major repairs.
Keywords: asphalt concrete with a complex-modified structure, service life of asphalt concrete pavements of highways, thermal aging coefficient, frost resistance coefficient, long-term water resistance coefficient.
