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.
