Summary: | Cold room studies of frost action in soils were performed as part of a continuing program of frost investigations aimed toward establishing and improving design and evaluation criteria for roads, highways and airfield runways constructed on soils which are subject to seasonal freezing and thawing. The present laboratory studies are being made chiefly to determine the quantitative effects of individual factors which influence ice segregation in soils, such as gradation, per cent finer than 0.02 mm., per cent stone, permeability, capillarity, proximity of water supply, compaction, and the initial degree of saturation in a closed system. The chief purpose of this paper is to present the testing program and methods and equipment that are being used. (Author) |
