FROST BEHAVIOR OF COMPACTED SOILS

THE FROST BEHAVIOR OF THREE COMPACTED SOILS SUBJECTED TO A UNIDIRECTIONAL PENETRATION OF FREEZING TEMPERATURE FROM THE TOP UNDER A TEMPERATURE GRADIENT OF 20 F/6 IN. WAS STUDIED. THE RESULTS INDICATED THAT RATE AND MAXIMUM DEPTH OF FREEZING TEMPERATURE PENETRATION, WATER CONTENT INCREASE, FROST HEAVE, AND DEVELOPMENT OF ICE SEGREGATION WERE DEPENDENT GREATLY ON SOIL TEXTURE COMPOSITIONS AND COMPACTION CONDITIONS INCLUDING INITIAL DEGREE OF SATURATION, MOLDING MOISTURE CONTENT, AND DRY DENSITY. ALTHOUGH SAND SIZE CONENT WAS CONSTANT, INCREASING THE CLAY SIZE CONTENT (SMALLER THAN 0.002MM) DECREASED FROST HEAVE, AVERAGE WATER CONTENT INCREASE, SIZE OF ICE LENSES, AND DEPTH OF ICE FRONT. IN GENERAL, DECREASING THE DRY DENSITY ONLY DECREASED THE RATE OF FROST PENETRATION AND INCREASED THE AMOUNT OF WATER CONTENT INCREASE AND TOTAL HEAVE. HOWEVER FROST HEAVE OF PROVIDENCE SILT COMPACTED BY USING STANDARD AASHO COMPACTION INCREASED AS MOLDING MOISTURE CONTENT INCREASED REGARDLESS OF THE CHANGE IN DRY DENSITY. FROST HEAVE INCREASED LINEARLY WITH AVERAGE WATER CONTENT INCREASE. THE RATE OF INCREASE, FOR A CONSTANT DEGREE OF SATURATION, INCREASED AS PERCENTAGE OF FINES DECREASED. /AUTHOR/
