Abstract. The article notes the relevance of the issues of ensuring frost resistance of structures, including road, in connection with the almost universal spread of the phenomenon of frost heaving in the territory of the Russian Federation. The question of known methods for determining the calculated characteristics of frost heaving of the soil, which is the initial characteristic of the calculation of structures for frost resistance, is considered. These methods include the standard method, the method VGU in two variants and the method ROSDORNII Institute. These methods are presented in the form of a flowchart with a detailed description of the individual blocks. The shortcomings of the normative method, which lead in some cases to unacceptable errors for engineering practice, are noted. The VGU method in the first embodiment is based only on the use of laboratory test data and plotting the intensity of frost heaving. In the second variant of the VGU method, the character of the intensity plot is taken on the basis of data from long-term field tests.

Keywords: frost heaving; deformation of frost heaving; intensity of frost heaving; normative method; VGU method; ROSDORNII method
