AbstractMeasurements of equilibrium ice lens heaving pressures in close-pack arrays of uniform size glass beads (Penner, 1966) in relation to bead size are in agreement with the theory of Everett and Haynes (1965). Similar heaving pressure measurements were determined on fractions of fragmental particles in the silt and fine sand range (Penner, 1967 and 1968). It is demonstrated that the smaller particles within a given range have a predominant influence on the equilibrium ice lens heaving pressures generated. From this it is concluded that the present criteria based on particles size -- with limits on the amount of fines permitted -- is an acceptable approach to defining the frost susceptibility of earth materials for soil engineering purposes.
