The durability of soil-steel structures may be governed by the frost effects in the soil backfill and under the invert. The mechanics of frost action and its harmful effects on conduits, especially pipe arches carrying water, are discussed. The present OHBD code and AASHTO specifications need to be revised to avoid placing frost-susceptible soil within the depth of frost penetration through the backfill, and the bedding should be provided with enough depth to avoid frost upheaval in the case of frost-susceptible native soil. Water seepage should also be prevented through the bedding to avoid infiltration of fine particles, which could change the character of clean granular soil under the invert into frost-susceptible soil.
