The Mechanics of Frost Heaving

The Journal of Geology, 1930
The old theory that frost heaving is due to change in volume of water frozen was based on experiments with closed systems.

Frost heave of roads

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980
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 ...

The problem of primary frost heave with frost penetration

Mathematical Methods in the Applied Sciences, 1995
AbstractThis 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, 2009
Frost 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.
