Abstract: Using the method of experimental-statistical modeling, the optimal concentration of the components of the wet asphalt-polymer slag concrete mixture was determined. It was found that the optimal ratio of components in the mixture in mass parts: screening of crushing of dump open-hearth slag – 100 %, burnt lime – 2%, liquefied bitumen modified with Butonal NS 198 latex (2 % wt.) – 8 %, mixing water – 14 %. It was found that wet asphalt slag concrete of optimized composition is characterized by the number of crystallization contacts 0,44. The compaction temperature range, which for wet asphalt-polymer slag concrete mixtures is 30…90 ° C, corresponds to the most compact arrangement of the particles of the mineral skeleton. The developed composition of wet asphalt-polymer slag concrete is characterized by sufficiently high deformation-strength and corrosive properties along with traditional hot fine-grained concrete. This indicates the expediency of their application for the current repair of the coatings of non-rigid road pavements of highways.
