Abstract

The urgency of the issue of expanding the forest infrastructure in the Russian Federation is increasing every year and faces economic, environmental and operational problems due to the wide geography of our country. The presented research is aimed at a comprehensive solution of the voiced problems. The use of industrial waste mixed with soils and alkaline additives will reduce the shortage of road construction materials, and the disposal of significant amounts of waste will have a positive impact on the environmental component. The materials presented in the study comply with SUST in terms of their physical and mechanical characteristics. Primary recommendations on the use of catalysts in sludge-soil mixtures are given.
