Predicting
frost heaving susceptibility of Arizona soils
L. J. Heidmann1 In 1971 a study was initiated to determine the heaving
susceptibility of six Arizona forest soils. A total of 15variaoles were used in a
stepwise regression analysis to develop an equation for predicting frost heaving
susceptibility.

Effect of bulk density on
frost heaving of six soils in Arizona
Interaction diagram showing the relation of soils and bulk density to mean frost
heaving per day for six soils in northern Arizona. The general trend was the same
for all soils. Bulk density was dominant in its effect on frost heaving, and this ...

Then it is evident that the latent heat, or more exactly, the energy released when
water becomes ice, is the source of work in frost-heaving. This fact may be
directly shown from Fig. 4. In a certain time Interval (dt) , the thickness (dhw) of
water is ...

If we neglect a volume change owing to the phase transition of pore water in situ,
the mean rate of frost heaving can be expressed as V/p, during the advance of
the freezing front by AX, where p, is the density of ice. In this experiment, the ...
