Summary The mechanism by which frost heave occurs when freezing temperatures, frost-susceptible materials and an adequate supply of water occur simultaneously is outlined. Index tests for identifying frost-susceptible materials (particularly sub-base aggregates) are discussed and emphasis is given to improvements in the Transport and Road ...

Frost heave and heaving pressure measurements in colliery shales
Canadian Geotechnical Journal, 1976The paper describes a technique for measuring the pressure generated when heaving is restrained in a frozen soil, freezing being achieved by thermoelectric cooling. Although steps were taken to minimize side wall resistance between the specimen and the test mould significant under-estimation of the pressure was unavoidable and further work is ...

The problem of primary frost heave with frost penetration
Mathematical Methods in the Applied Sciences, 1995AbstractThis paper is concerned with a mathematical model for the phenomenon of primary frost heave with frost penetration, which appears in the freezing process of wet soil. The problem is formulated in the form of a free boundary problem with two free boundaries. It is shown that there exists a unique classical solution for this problem.

Foundation Design for Frost Heave
Cold Regions Engineering 2009, 2009Frost heave is the heaving of the ground surface when frost-susceptible soils, in conjunction with high water table or surface water infiltration, freeze. This paper discusses the foundation design strategy for frost-heave forces in areas with substantial frost depths. Only foundations in seasonal frost areas are discussed.
