Frost Action. Frost action, which can be quite detrimental to pavements because of its effect on the underlying subgrade, can be divided into "frost heave" and "thaw weakening". "Frost heave" is an upward movement of the subgrade resulting from the expansion of accumulated soil moisture as it freezes, while "thaw weakening" is a weakened subgrade condition resulting from soil ...
