Abstract: Currently, financing of the road industry in the territory of the Donetsk People’s Republic is carried out in incomplete volume for a number of reasons independent of the road industry itself. Therefore, the question arises of finding new, more economical materials for the production of asphalt-concrete mixes to perform repairs and technological operations that allow you to perform these works. The possibility of using materials obtained by milling old asphalt concrete in the repair of non-rigid road surface, which is formed in large quantities, is considered. The use of regenerated asphalt concrete will reduce the cost of new expensive mineral materials (crushed stone, sand, mineral powder) and organic binder. When performing repairs, the old asphalt concrete is removed, which can be used as an independent material, or as a component of the newly prepared asphalt concrete mixture. The regenerated asphalt mix requires a slight improvement in the physical and mechanical properties of bitumen found in old asphalt concrete.
Keywords: old asphalt concrete, regeneration of asphalt concrete surfaces, asphalt granulate, bitumen, modification, modifying additives.
