Abstract: It has been found that the most rational way to increase the durability of asphalt concrete is the complex control of the microstructure by modifying bitumen with ethylene glycidyl methacrylate in combination with polyphosphoric acid. On the example of the system: «hot asphalt polymer concrete modified with ethylene glycidyl-methacrylate» a theoretical and experimental method has been performed to obtain durable composite materials. It has been found that one of the most effective methods of modifying asphalt concrete mixtures providing matrix elasticity and strong bonding on the interface of phases «organic binding (OB) is mineral material» as well as the stability of the properties of concretes on organic binders in the process of technological processing and operation, is the complex regulation of the asphalt concrete microstructure by the introduction of an organic binder polymer combined with it or a complex admixture (polymer in combination with active dispersed filler) and mechanoactivation of mineral powder surface (MP) with a solution of a polymer or oligomer containing functional groups (carbamide formaldehyde resin, epoxy resins, polymer-containing epoxy resin production wastes, cubic styrene distillation residues, etc.).
Keywords: oil road bitumen, asphalt polymer concrete, mineral powder, weather resistance, modifier, complex modification.
