The freeze-thaw problem is discussed which occurs at or near culverts installed in highway earthworks. In an attempt to elucidate the thermal conditions in connection with soil freezing, thawing and soil anti-frost insulation around culvert walls, attention is drawn to the thermal system soil-culvert-temperature. This thermal system explains the heat and moisture migration in soil under the influence of freezing thermal gradients, and may indicate savings in the amount and construction of earthworks by consideration of: (1) the thickness of the unfrozen overburden soil between the crest of the culvert as related to the frost penetration depth below the surface of the pavement; and (2) the repairs on road surfaces brought about by culvert settlements upon thawing of soil around culverts. Theoretically, insulation may be installed around the inside of the culvert walls. However, in such cases, the culvert insulation should have sufficient thermal and strength properties to prevent its being abraded and quickly worn out by sediment carrying drainage waters flowing through the culvert. Under these conditions, the insulation will fail prematurely. Anti-frost insulation, must therefore, be installed around the outside walls of a culvert.
