THE RESULTS OF TESTS TO DETERMINE THE EXPANSIVE PROPERTIES OF SOILS

THE STUDY OF THE SWELL OF SOILS WAS BEGUN AFTER IT WAS FOUND THAT SOIL SWELL WAS DIRECTLY ASSOCIATED WITH THE DISTORTION OR WARPING OF CONCRETE PAVEMENTS. RESULTS SHOW THAT THE AMOUNT OF SWELL IS DEPENDENT UPON THE CHARACTERISTICS OF THE SOIL ITSELF AS INDICATED BY THE TEST CONSTANTS; UPON THE STRUCTURAL ARRANGEMENT OF THE SOIL IN ITS NATURAL STATE; AND UPON ITS STATE OF COMPACTION AND INITIAL MOISTURE CONTENT. THE GREATEST SWELL WAS OBSERVED ON EXPANSIVE SOILS WHICH EXISTED IN A COMPARATIVELY DRY, COMPACT STATE PRIOR TO BEING ALLOWED TO ADSORB WATER AND SWELL. EXPANSIVE SOILS EXHIBITED THE LEAST SWELL WHEN THEY WERE COMPACTED TO MAXIMUM DENSITY AT MOISTURE CONTENTS CLOSELY APPROACHING THEIR LOWER PLASTIC LIMITS. /AUTHOR/
