| Summary: | The limitations of the presently available techniques concerning the prediction of frost effects were pointed out. A freezing apparatus was designed and constructed to conduct laboratory freezing tests on Arctic soils. The experimental observations did not agree with predictions based on the currently used grain-size criterion. A new frost-susceptibility concept was introduced end a method of evaluating relative frost-susceptibility was proposed. Predicted values were successfully compared with observed frost effects. The relative importance of external conditions was discussed for the particular case of rapid freezing. Laboratory observations were applied with success to the prediction of frost penetration for Lake Hazen conditions. |
