### Abstract
 | 
			
		||||
 | 
			
		||||
> 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 charac- terized 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.
