The article shows a picture of climatic changes in the Arctic zone, presents the advantages of reinforced concrete sleepers, argues the necessity of using in the Arctic zone sleeper materials with high strength and frost resistance, high deformation and corrosion resistance, gives a brief historical overview of the contribution of St. Petersburg University of Railway Transport to the development of highly effective materials for the production of critical structural elements of the upper structure of the railway Data on the change in the strength and deformation characteristics of slagalkali concrete for reinforced concrete trusses after 10 years of operation are presented. The paper assesses the state of the reinforcement and the factors influencing the possible corrosion development: dynamics of alkali binding, composition of passivating films and the adjacent layer of concrete, microstructural analysis of the reinforcement.
