Abstract : The report describes results of a search for additives to reduce the frost susceptibility of soil. The additives are divided into four primary function groups: (1) void fillers and cementing agents, (2) aggregants, (3) waterproofers, and (4) dispersants. Tests showed that a dispersant, tetrasodium pyrophosphate (TSPP), and an aggregant, ferric chloride, possess good frost-heave-modifying capabilities. A preliminary field test indicated that TSPP can reduce heave significantly under natural conditions. The long-term effectiveness under field condition is still to be determined. Laboratory tests were conducted to determine the effect of prolonged water attack on the frost-heave-modifying capabilities of 0.3% treatments of TSPP and ferric chloride when used with two silty sandy gravels.
