Abstract

This study analyzes the physico-mechanical properties and features of organo-mineral soils containing humic substances in order to determine their potential for use in road construction. The patterns of formation of such soils in various climatic zones of Russia, where they occupy significant territories, have been studied. The classification of soils based on the quantitative content of humic components was carried out, followed by the determination of their granulometric composition. The article presents the results of experimental studies on strengthening soils with a high content of organic substances for their further use in road construction. The effectiveness of an integrated approach to strengthening humus-containing soils by using various binding components: cement, bitumen and polymer materials in combination with sand additives is investigated. The physicochemical processes of interaction between the structural elements of the soil and stabilizing substances have been studied. Optimal dosages of binders and moisture characteristics of soil mixtures for various types of organo-mineral soils have been established, ensuring maximum strengthening efficiency.
