Abstract
Frost-susceptibility of soils can be defined by the results of laboratory tests of soil samples in terms of freezing rate is close to in-situ and water is freely available to sample, i.e. as in open system. Such tests are time-consuming and require the use of expensive equipment. So it would be usefully to find a simpler way to assess frost-susceptibility of soils, namely, by the parameter associated with the change in water content of soil sample when freezing without water supply, i.e. as in closed system. The article deals with the results of experiments of clay and technogenic (man-made) soils tested in open and closed systems. Test results show the possibility of assessing the frost-susceptibility of soils by a parameter which is related with a change in water content profile during soil freezing in the closed system. A close correlation between this parameter and the frost heave of soils tested in the open system is obtained for typical clays of the Arkhangelsk region and technogenic (man-made) soils.
