The object of research is the stress-strain status of reinforced structures restored by the method of injection impregnation. The subject of the research is strength, deformability and crack resistance of reinforced bridge structures and culverts restored by injection materials under the influence of external loading. The purpose of the study is to obtain theoretically and experimentally validated data on the strength, deformability and crack resistance of reinforced structures restored by the method of injection impregnation and the development of appropriate guidelines for the use of this method for the restoration of highway bridges and culverts structures. The results of scientific data on the research and scientific and technological support for the restoration of reinforced structures of bridges and culverts by the method of injection impregnation using polymeric solutions were studied and analyzed. Experimental research program is prepared. In accordance with the research program, test samples were made and experimental studies on the restoration of reinforced beams by injection impregnation method were carried out. The obtained indicators of strength, deformability and crack resistance allowed qualitative and quantitative evaluation of reinforced structures performance restored by the method of injection impregnation.
