Abstract: The economic attractiveness of cold recycling technology provides, first of all, the reuse of the existing material on the road for the arrangement of new pavement layers, so there is no need to equip special sites for the storage and disposal of old asphalt concrete. The essence of cold recycling technology which is most commonly used for arranging the subbase in Ukraine is that the defective and destroyed layers of road pavement are reinforced on-site by combined additives of organic and mineral binders. Cold recycling by complexity of works is divided into several types depending on the depth of milling. The choice of a rehabilitation type depends mainly on the general state of the pavement structure state which is determined before the beginning of repair work. In Ukraine, the main focus of R&D in cold recycling technology is the use of new materials such as fiber - basalt or polymer, stabilizing additives, industrial waste - slag of various types of industries or other byproducts. Conducted research has shown that the use of organic and mineral mixtures from an optimal mix design with the introduction of basalt fibers increases the crack resistance and durability of the arranged subbase.
