ADDITIVES FOR MODIFYING THE FROST SUSCEPTIBILITY OF SOILS - PART II - FINAL TECHNICAL REPT 1956-1958

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. /AUTHOR/
