Abstract
Although it is widely recognized that lime-stabilized and cement-stabilized soil restrict frost heave, little is known about it's mechanism. It is generally thought that a decrease of the permeability or an increase of the bonding strength between soil particles contribute to the restriction of frost heave in stabilized soil.
In this paper, changes of the permeability and pF characteristics in lime-stabilized soil were investigated and their effects on frost heave were discussed. As a result, it is found that the permeability and the bonding strength do not affect on the frost heave very much. However, there was a correlation between the amount of adsorbed water obtained by pF test and the frost heave.
