The article presents the results of the research of impregnation composition for concrete roads, which allows to improve the ice-phobic properties of the coating. The impregnating composition is based on keratin-containing components and water-soluble polymer. Studies of qualitative indicators of the composition were carried out in laboratory conditions: determination of the optimal water concentrate of impregnation composition was made by measuring water absorption capacity of samples, and the assessment of durability (wear resistance to mechanical impacts or percentage of abrasion) was carried out by model tests with wheel loadings.
