THE EFFECT OF CHEMICAL FACTORS ON THE MECHANICAL STABILITY OF A PUTNAM CLAY SOIL IS INVESTIGATED. THROUGH CHEMICAL TREATMENT AND THE MEDIUM OF BASE EXCHANGE THIS SOIL WAS ALTERED TO PRODUCE HOMOIONIC SOILS WHOSES BASES WERE (1) SODIUM, (2) POTASSIUM, (3) MAGNESIUM, (4) CALCIUM AND (5) ALUMINUM. THESE MODIFIED SOILS ALONG WITH THE NATURAL SOIL WERE TESTED, BY STANDARD PROCEDURES, TO DETERMINE THE FOLLOWING CHARACTERISTICS: (1) SPECIFIC GRAVITY, (2) SIZE COMPOSITION, (3) LIQUID AND PLASTIC LIMITS, (4) SHRINKAGE LIMIT, (5) FIELD AND VACUUM MOISTURE EQUIVALENTS, (6) OPTIMUM MOISTURE CONTENT FOR COMPACTION, (7) TOTAL AND RATE OF CONSOLIDATION, (8) PERMEABILITY, AND (9) SHEAR TESTS BY TWO METHODS. THE RELATIONSHIP BETWEEN THE PHYSICO-CHEMICAL AND THE MECHANICAL PROPERTIES OF THE DIFFERENT SOIL SYSTEMS ARE DISCUSSED. /AUTHOR/
