Annotation Engineering and construction in areas of seasonal freezing requires special measures to reduce the depth of soil freezing at the bases. The paper highlights the measures to reduce the seasonal freezing and frost heaving soils. One of the measures to reduce frost heaving soils is thermal protection, those, insulating device (antifreeze) layers in constructions engineering structures bases. The laboratory simulation seasonal freezing of soil at the specially designed experimental setup has been carried out, representing an insulated tray compactor to generate a vertical temperature gradient and a free inflow of water to the freezing front. The authors have investigated the dynamics of the temperature, humidity and strain distribution in frozen ground using a surface insulating layer of granular foamed glass ceramics (GFGC) and extruded polystyrene (EP) compared to the ground without thermal insulation. Application of GFGC and EP equally contributed to the formation in the ground water and thermal regime, significantly reduces the development of strains of frost heaving, despite the freezing of the soil. As a result found a significant reduction in the depth of soil freezing and frost heaving absence of deformations in cases of insulating materials. The findings suggest that maintaining during the experiment equal to the thermal resistance of the layers of two types of insulation, despite their different structure. The stability of thermal conductivity at the soil surface GFGC insulation is confirmed. The interrelation with the frost heaving deformation temperature and humidity distribution in the depth of soil, taking into account the inflow of water to the freezing front. The experiments demonstrate the importance of taking into account this relationship occurs when the water-heat mode character deformations. The industrial testing of the investigated model with the use of GFGC has been held during the construction of an experimental road section \"Beskozobovo-Evsin-Lamensky\" km 47 + 540–47 + 690 km (Tyumen region, Golyshmanovsky district).
