MODIFICATION OF FROST-HEAVING OF SOILS WITH ADDITIVES

A THREE-YEAR SEARCH IS DESCRIBED FOR ADDITIVES TO REDUCE THE FROST SUSCEPTIBILITY OF SOIL. FIFTEEN SOILS AND ABOUT FORTY ADDITIVES HAVE BEEN TESTED. A DISCUSSION OF THE THEORETICAL CONSIDERATIONS FOR THE CHOICE OF ADDITIVES IS PRESENTED. THE ADDITIVES ARE DIVIDED INTO FOUR GROUPS: (1) VOID PLUGGERS AND CEMENTS, (2) AGGREGATES, (3) DISPERSANTS, AND (4) WATER-PROOFERS -- ACCORDING TO THEIR ACTION IN SOIL. TESTS REPORTED HEREIN SHOW A NUMBER OF ADDITIVES, ESPECIALLY DISPERSANTS AND POLYVALENT CATION SALTS, MERIT FURTHER LABORATORY EVALUATION. OTHER TESTS ON SOILS TREATED WITH RESINS AND WATERPROOFERS HAVE ALSO INDICATED PROMISING RESULTS. A SMALL-SCALE FIELD TEST SHOWED A LABORATORY-PROVED DISPERSANT TO BE EFFECTIVE UNDER FIELD CONDITIONS, MEASUREMENTS MADE DURING THE SECOND FREEZING CYCLE SHOWED NO REDUCTION IN THE POTENCY OF THE DISPERSANT TREATMENT. FOUR FREEZE-THAW CYCLES ON FOUR SOILS TESTED IN THE LABORATORY ALSO HAD NO ADVERSE EFFECTS. /AUTHOR/
