Performance of a frost heave cell for low-temperature-gradient experiments
One limitation of frost heave experimental research has been the necessity to use short soil samples to achieve one- dimensional heat flow. The temperature profile is then characterized by a high gradient and the soil has a very narrow freezing fringe. This fringe, a partly frozen band of soil, is t...

One limitation of frost heave experimental research has been the necessity to use short soil samples to achieve one- dimensional heat flow. The temperature profile is then characterized by a high gradient and the soil has a very narrow freezing fringe.

This paper reports the design and testing of an experimental apparatus that permits a low thermal gradient and thereby an enlarged freezing fringe.
