Review article

The present study was aimed at assessing in an experimental way the values of heaving rate for the Russian system of soil heaving classification. Based on the laboratory study of the frost heaving process of 25 different soil samples, there were obtained the values of heaving degree and frost heaving rate for each of them. Based on the analysis of the obtained data, the authors proposed values of frost heaving rates at the boundaries between different soil classes to be included in the Russian system of soil classification by heaving degree. In addition, there is proposed an approximation function that makes it possible to transfer from the value of the relative deformation of frost heaving to the frost heaving rate, which helps harmonizing the experience of Russian and foreign scientists and engineers.
