Abstract: This article focuses on the experimental research of the impact of additives of surface active agents upon the strength of the frozen dispersed soils. The work touches on the problem of finding new theoretical approaches towards mechanical properties of dispersed soils accounting for presence of free surface energy and impact of the physical chemistry factors upon the behavior and properties of the soils. Substantiation is made on the physical chemistry approach as the most promising one in this area. Pyotr Rebinder’s mechanism for strengthening thawed soils through the effects of the surface active agents is presented in this research. Experimental research was conducted on the strength characteristics of the frozen dispersed soils with use of surfactants and without additives. The conducted research yielded experimental curve relationship of the maximal strength from time for frozen sand and loam with surfactants and without.
