dc.descriptionSummary: This report describes the research conducted during the Fiscal Year 1954. It is a continuation of work done during Fiscal Years 1952 and 1953 which was presented in Appendixes C and D, Volume 2, of the report by the Arctic Construction and Frost Effects Laboratory (ACFEL Technical Report 43, Vol. 2) The immediate objectives were: (1) to correlate the composition of fines and the rate of frost heave of soil and (2) to find additives which in trace quantities can reduce the frost susceptibility of soil. The addition of sodium montmorillonite and of peat fines to a sandy clay, a silt and a clay soil generally resulted in a decrease in rate of frost heave. Both the hydrated and dehydrated forms of a natural halloysite when frozen with water available for ice segregation were found to be highly frost-susceptible, with the hydrated form more susceptible. A number of chemical additives were effective as frost modifiers, with dispersants showing the most promise. Some dispersants, at a material cost as low as of about 1 to 3 cents per cubic foot of soil, reduced the rate of heave of a sandy clay and a silt to less than half of the values of the untreated soils. Frost tests were performed and reported on 32 additives; 12 of these are listed which will reduce the rate of heave by 50 percent or more when one percent or less of additive is used. Ten specific conclusions are given. Continuation of the research work is recommended and eleven specific investigations are proposed. A reference bibliography is included.-
