For economic efficiency, the authors offer to conduct an experimental study of the deformed state of thesub-grade model on permafrost soils in the laboratory environment in a closed system (without a water flow) applying a geometric scale value of M 1:30 and time scale of M 1:900. The description of the research flume, which allows simulating not only the deformed state of the linear structure, but also the temperature regime, is given. During the study, the defects were photo-recorded and the deformations of the structure were measured. Distribution isolines of vertical movements while freezing-thawing were built in the software system «Python», a thermogram of temperature changes in the body of the roadbed and the base of the road is given. The main conclusions of the research are formulated.
