CHEMICAL ADDITIVES TO REDUCE FROST HEAVE AND WATER ACCUMULATION IN SOILS, WITH DISCUSSION AND CLOSURE

SOIL WATERPROOFING CHEMICALS ARE KNOWN TO REDUCE FROST HEAVE IN SOILS, PARTICULARLY WHEN SOILS ARE DRIED; THE PRESENT STUDY DEMONSTRATES THAT THESE CHEMICALS WORK IN MOIST SOILS AS WELL. THE MECHANISM AND LIMITATIONS ARE PARTLY DEFINED IN THIS PAPER. A MODEL SOIL WATERPFOOFING COMPOUND, 4-TERT-BUTYLCATECHOL (TCB), WAS STUDIED AS REPRESENTATIVE OF THE GENERAL GROUP. WATER ABSORPTION TO GROWING ICE LENSES WAS MEASURED AS AN INDICATION OF FROST-HEAVE RATES. CAPILLARY CONDUCTIVITY WAS ALSO MEASURED AND CORRELATED TO HEAVE AND TREATABILITY. AS LITTLE AS 0.01 PERCENT TCB PRODUCED MINIMUM ICE LENS GROWTH AND CAPILLARY FLOW IN SOME SOILS. A-4 SOILS RESPONDED WELL TO TREATMENT, WHEREAS SOILS CONTAINING MORE THAN 50 PERCENT CLAY DID NOT. A SIMPLE HYDRAULIC CONDUCTIVITY TEST SHOULD BE CONSIDERED AS A MAJOR SOIL FROST-SUSCEPTIBILITY CRITERION. /AUTHOR/
