Annotation: Estimated service life of asphalt concrete road pavements, I-a and I-b technical categories before major overhaul (10–12 years) in the Donetsk People’s Republic and in Russia is not maintained. After five years of operation, they need major repairs [1–3]. The properties of asphalt concrete – a composite material with a coagulation type of contacts – are determined, first of all, by the quality of the organic binder, a rational combination of types of macrostructure, mesostructure and microstructure of the mineral backbone, pore space, as well as the energy of interaction at the interface between the phases «organic binder–mineral material» [4–10]. Thus, it is necessary to develop such methods of directed regulation of the structure and properties of oil road bitumen and increasing the energy interaction at the interface between the phases «organic binder–mineral material» Donetsk People’s Republic and in Russia effectively resist aging, shear deformations, low-temperature and fatigue cracking, and cyclic transport loads [11–19].
