Frost Susceptibility
There are many factors that affect frost susceptibility, including clay mineralogy and the number of freeze‐thaw cycles, but four factors are of particular significance in affecting the amount of ice segregation during soil freezing: the pore size of the soil; the moisture supply; the rate of heat extraction; and the confining pressure. The test that is usually considered to be the defining measurement of frost susceptibility is the frost heave test which essentially consists of freezing a soil specimen in a mould by cooling it at the top face, therefore applying a temperature gradient, and measuring the amount of frost heave. Reliance on frost heave alone may not be sufficient since soils may exhibit little heave but still show appreciable weakening on thawing. To overcome these problems, methods have been developed that rely on more standard testing to identify frost‐susceptible soils, principally grading, moisture content and plasticity testing.
