Frost Sensitivity Of Core Materials: Case Histories

Waterloo Lake Dam is a simple zoned earth-rockfill structure with a wide central impervious core of silt. Since the first winter, frost penetration of the silt core has caused gradual deterioration of the dam. Pronounced longitudinal cracking and silt outflows have been evident along almost the entire length of the crest. This paper presents details of both in-situ and laboratory test programs and the subsequent construction of the White Lake and Charlot River Dams.
