| Description: | Technical Report Abstract: Fifty-two additives to reduce the frost susceptibility of soil were tested on twenty-five soils. The theoretical considerations underlying the choice of additives are discussed. The additives are divided into five groups according to their action in soil: 1) void fillers and cements, 2) aggregants, 3) metallic salts, 4) waterproofers, and 5) dispersants. A number of additives, especially dispersants and polyvalent cation salts, merit further laboratory evaluation. Resins and waterproofers also look promising. Four freeze-thaw cycles on four different dispersant-treated soils tested in the laboratory showed no diminution of effectiveness of treatment. A small-scale field test showed a laboratory-proved dispersant to be effective under field conditions; measurements made over two seasonal freezing cycles showed retention of original effectiveness of the dispersant treatment. |
