According to the results of long-term field and laboratory researches, the dynamics and regularities of frost heaving of coarse clustic rocks in the conditions of the cryolithozone degradation have been reviewed. The correlation between the changes in types of seasonal freezing and thawing of rocks and the changes in their frost susceptibility at climate warming has been revealed. It has been proved that frost susceptibility of coarse clustic rocks can vary within a wide range of limits and can be excessively frost susceptible depending on freezing conditions.
