Abstract:

The variation of soil properties during the freeze-thaw cycles, especially the reduction of soil strength in the thaw stages, is the major cause of pavement damage. Preventing the reduced soil strength due to thaw is also critical for cold region transportation facilities, especially those underlain by permafrost. This paper introduces the experimental program to study on the effects of freeze-thaw on soil mechanical behaviors. An innovative TDR tube sensor was developed to nondestructively monitor the freeze/thaw process, from which the degree of freeze/thaw can be accurately determined. With the assistance of this tool, the effects of freeze/thaw on the soil mechanical behaviors including the deformation modulus, peak strength and volume change are investigated. From these measured soil mechanical properties, a simplified analyses is given to estimate the soil pressure on imbedded structures induced by freezing.
