Abstract
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 the most important region to consider, since it is in this zone that suction potentials are developed, causing frost heave. This paper reports the design and testing of an experimental apparatus that permits a low thermal gradient and thereby an enlarged freezing fringe.
