AbstractHeave and moisture intake and explusion were measured in four soil samples at different overburden pressures from 0.5 to 4 kg/cm². A step change in temperature, a requirement of the procedure, was imposed at one end of the sample, which was originally at a uniform temperature, to induce unidirectional freezing in a specially-designed test cell. Soils were medium in texture and had obtained along the proposed Mackenzie HIghway, N.W.T. The response to pressure and freezing conditions imposed were similar for all soils. Of particular note was the constancy in the heave rate throughout each test. At high pressures, water was expelled from the sample initially, but in all cases this was followed by water intake after the rate of frost penetration had decreased.
