|
|
<blockquote>
|
|
<p>Frost heave is typically associated with the formation of segregation ice in
|
|
fine-grained soil. Coarse-grained soil is generally considered to be non-frost
|
|
susceptible. Field observations and laboratory experiments show that
|
|
coarse-grained soil can be extremely ice-rich in specific conditions. Previous
|
|
studies have shown that oscillation of the frozen-unfrozen boundary can lead to
|
|
the formation of ice by a mechanism different from the segregation ice
|
|
mechanism. Conditions related to the formation of ice in coarse-grained soil
|
|
were investigated using modern laboratory techniques. Fourteen tests were
|
|
conducted on five soil types. The thickness of soil subjected to freeze-thaw
|
|
cycles was varied and controlled by the magnitude and duration of applied soil
|
|
temperatures. The thickness of the ice formed increased when the sample
|
|
drainage was limited or prevented during cooling. Under specific conditions,
|
|
the formation of a discrete ice layer was observed in coarse-grained soils.
|
|
Seven samples were scanned with the μCT scanner at the completion of the
|
|
warming and cooling tests. The sub-samples scanned were analyzed in 2D
|
|
cross-sections, and characterized as 3D reconstructions. Frost heave induced
|
|
by the formation of ice was observed in both fine- and coarse-grained soils,
|
|
including soils that were found to be traditionally non-frost susceptible.</p>
