Registration Date 06-02-2024 Organization Ukrainian State University of Railway Transport popup.description2 As part of the research work, the following was performed: collection and analysis of new data on damage to railway transport structures and facilities, clarification of the causes of damage and development of ideas about the mechanisms of destructive processes; analytical review of new materials and constructive and technological solutions for protection and repair; theoretical studies on the development of ideas about the mechanisms of destructive processes, the protective effect of composite materials (СМ), the formation of their properties; experimental studies of the dependence of the properties of СМ on their composition and indicators of technological influence; the development of methods of assigning compositions and the development of compositions of СМ for protection and repair with specified properties, including electrical conductivity, modulus of deformation; development of constructive and technological solutions for protection and repair with the use of СМ. The mechanisms of the flow of leakage currents through the reinforced concrete structures of the under-rail foundations - sleepers and ballastless bridge deck, passenger platforms, as well as their corrosive effects - have been established. Improvements are substantiated and methods of protection by draining leakage currents with conductive screens are improved. The compositions of composite based on mineral binders and conductive fillers for these screens have been substantiated and developed. The required physical and mechanical properties of the paving layer between the ballastless bridge deck and the beams of railway bridges have been substantiated, the composition of dispersion-reinforced СМ based on mineral binders for the paving layer with the specified properties has been substantiated and developed, as well as the methods of arranging the paving layer during installation and repair bridge web. The practical significance of the results of the work extends to construction and civil engineeri Product Description popup.authors Borziak Olha S.
