“…The water-thermal regime of the soil in laboratory conditions was provided by maintaining the two conditions:  freezing of soil samples was performed only from the upper end of the cylinder;  the temperature regime was set up on the lower and upper thermal plates as well as the surfaces of the soil samples. The methodology of this work has followed the existing standards and knowledge on the evaluation of the frost heave in construction engineering works (Brown, 1965;Nishikawa and Sakuraba, 2002).…”

Current paper focuses on the laboratory experiments performed wit aim to test the deformation in the frozen loam soil specimens. Loam frozen soils are subject to the external effects, such as climate and environmental impacts including temperature changes. Soil heave is one of the key features restraining possible area development: construction of buildings, roads and railways. Necessarily, this requires the improvements of methods of the assessment of heave. This research evaluated the compressive strength and deformation in several specimens of the frozen soil. The approach included varying load and physical properties of soil specimens: porosity, pore filling, moisture, density of soil particles and dry soil density. Besides during the experiment, the external conditions were changed: decreased temperature and increased load pressure. The experiment is based on the UPG-MG4-01. The paper presented the laboratory tests of heave and compressive strength of the frozen soils using applied geotechnical methods.
