We give the substantiation of the choice of methods and devices for laboratory modeling of the processes of freezing and heaving of soils in order to study their heaving properties and freezing parameters for verification of the developed mathematical methods of the process modeling. The methods under consideration make it possible to set and control in automated mode the dynamics of the temperature state, heat and water flows, heaving and shrinkage deformations, moisture content and bulk density, pore hydraulic pressure, and formation of segregation ice in freezing soils through the use of time-lapse video recording and the simulation of external mechanical and hydraulic loads.
