AbstractMaximum heaving pressures caused by ice lens growth were determined experimentally for saturated specimens consisting of fragmental particles in several size ranges. Theoretical predictions show that the pores produced by the smaller particles in the system are responsible for the maximum heaving pressures measured. The suggestion is that the ice- water interface assumes an undulating configuration over the smaller pores when ice proliferation stops, and hence heaving pressures rise to a maxiumum. Particle size seems to be an adequate basis for predicting frost susceptibility in practice although the exact amounts and size limits permissible have not been evaluated. The nature of the failure caused by frost action is not the same for all engineering structures. Failures by "rate of heave" and " heaving pressure" should both be considered if the possibility of frost damage exists. The results substantiate earlier conclusions that there is no sharp dividing line between frost-heaving and nonfrost-heaving soils.
