Role of the electric double layer in the mechanism of frost heaving
Cass, L. A.; Miller, Robert D. (Robert David), 1922-
Research ReportSummary: It is suggested that the osmotic activity of the electrical double layer on mineral particles can account for the heaving phenomenon in soils, and equations are given relating the osmotic pressure (and freezing temperature) of water at the base of a growing ice lens to overburden pressure, depth of water table, depth to the conducting stratum, hydraulic conductivity of soil, and rate of heave. Water flows to the ice face ordinarily by hydraulic conduction, but by diffusion in the unfrozen film between the uppermost particles and the underside of the ice lens. Coarse materials show little heave because of diffusion limitations on recharge of the unfrozen film. The theory of Jackson and Chalmers that super-cooling is required for heaving is denied, and a "solution model" is proposed in which heaving can occur in the absence of soil. Various methods of modifying or controlling frost heaving are reviewed in the light of the theory, and experiments are proposed for evaluating the theory.
