Abstract
The current regulatory documents for infrastructure construction indicate the use of only thawed, mainly sandy soils. When erecting embankments during the winter period, a limited number of applied frozen soils are allowed. In this case, the stability and strength of the soil massif decrease. The absence of thawed soils in the regions of Siberia and the Arctic requires an expansion of the types of soils used, one of which is frozen soils. We have developed the designs of the subgrade that allow using frozen soils, enclosed in geosynthetic cages or without them. Increasing the stability and strength of the embankment by creating a dense soil skeleton is one of the scientific issues, which is solved in this article by applying the theory of granular media. In practice, the formation of dense systems from frozen soils is based on two principles: the method of dense mixtures and the method of impregnation, where the main layer of frozen soil is impregnated from above with dry frozen soils. Almost by selection of the composition, you can achieve the maximum density.
