Аннотация: Variation in physical properties of soil depends heavily on freezing process duringseasonal changes. Seasonal changes in cold humid regions lead to increasing of soiltransformation speed. In the late autumn, soil profile is saturated with water through fallout.During winter, soil solution freezing leads to soil volume increasing due to water transition intothe ice. Soil solution freezes in larger pores and the moment water flow stops, water phasetransition leads to smaller pores and capillary deformation. Intensity of pore and capillarydepletion will define extent of density changes during freezing. Rapidly developing urbanizationprocess requires expansion of urban greening and tree planting, which can be successfully doneby sustainable artificial soil implementation for each region, according to its climate conditionsand pedogenesis. In order to observe possible porosity and structure changes in artificial soilsand change rate due to freeze-thaw phenomenon, we have performed an experiment with a useof artificial soil models and then we have applied X˗Ray computer microtomography method toanalyse soil pore space and its composition. As a result, we have seen significant compactionand pore diameter differentiation, as well as geometrical configuration changes
