Abstract
A soil frost susceptibility test is proposed. The method involves the unidirectional freezing of a saturated sample by imposing a step freezing temperature at one end of the specimen and measuring the heave rate. The two most important conditions that influence heave rate during the test are the overburden pressure and the freezing temperature. Results show that the heave rate can be expressed as an exponential function of the applied overburden/freezing temperature ratio. The desirable features of the proposed freezing technique and the method of interpreting the results are outlined.
