Abstract

Open-system frost heave tests were performed on a silty clay using a lower boundary condition of +2°C and unidirectional freezing at -10°c from the surface, or freezing and thawing with an upper boundary temperature that cycled from -10°C to +10°C or from -10°C to 0°C. The amont of frost heave, the distribution of moisture at the end of the experiment and the final dry density profiles all differed for the 3 cases. The experiments demonstrate that freeze-thaw history is important in assessing or predicting the frost heave of silty clays
