Аннотация
The effect produced with the use of granulated foam-glass ceramic, a product of the processing of opal cristobalite rocks, for the protection of a roadbed against seasonal freezing is evaluated. Studies of the temperature conditions of frozen oil without heat insulation and of frozen soil insulated with extruded foam polystyrene or granulated foam-glass ceramic are performed. It is shown that a layer of foam-glass ceramic (in the dry state) and a layer of extruded foam polystyrene equivalent in terms of heat resistance produce roughly the same effect on freezing of soil, as a result of which the freezing depth is reduced several fold. An increase in the freezing depth is observed in the case of moist foam-glass ceramic.
