Abstract:

In the presents work, the authors have carried out a field study of moisture transfer processes in highway subgrades in a cold region during freezing and laboratory experiments on freezing samples of silicified soils used as a capillary barrier. The study showed that the creation of a capillary barrier from an injected solution, blocking the access of groundwater to the freezing zone, will reduce the amount of heaving to permissible values. Based on the results of laboratory studies, an exponential dependence of the relative deformation due to frost heaving on the relative height of soil silicatization in the freezing zone has been established. For creating a capillary barrier in the already existing subgrade, the authors have proposed designs of injection-silicified soils and substantiated the use of such soils.

Key words: capillary barrier, subgrade, soil injection, silicified soil, cold regions
