Frost Investigations. Fiscal Year 1951. Cold Room Studies. Volume 1.
Abstract
The report presents the results of cold room studies of frost action in soils which were performed between February 1950 and the end of Fiscal Year 1951 by the Frost Effects Laboratory, New England Division, Corps of Engineers. The investigations are being conducted for the Airfield Branch, Office of the Chief of Engineers, Department of the Army, as part of a continuing program of frost investigations aimed toward establishing and improving engineering design and evaluation criteria for roads, highways and airfield pavements constructed on soils which are subject to seasonal freezing and thawing. The studies are being conducted chiefly to determine the effects of each of the individual factors which influence ice segregation in soils, including gradation, per cent finer than 0.02 mm., per cent and size of aggregate greater than 2.0 mm., degree of compaction, surcharge pressures, initial degree of saturation in a closed system, alternate cycles of freeze-thaw, admixtures, capillarity, condensation, proximity of water supply, rate of penetration of 32F. temperature, mineral composition of fine soil fraction, and permeability.
