PROPERTIES OF FIELD COMPACTED SOILS

SOIL COMPACTION TESTS WERE CONDUCTED IN THE FIELD BY CONSTRUCTING TEST SECTIONS OF SOIL IN SINGLE LIFTS ON A PREPARED FOUNDATION USING A VARIETY OF COMMERCIAL ROLLERS. THE TEST RESULTS WERE OBTAINED USING THE FOLLOWING SPECIFIC INDEPENDENT VARIABLES: /1/ FOUR SUBGRADE SOILS, A-6/13/, A- 6/9/, A-4/1/ AND A-4/8/, /2/ FOUR MOISTURE CONTENTS FOR EACH SOIL RANGING FROM DRY TO WET OF OPTIMUM, /3/ TWO LIFT THICKNESSES, 6 AND 12 IN., /4/ FOUR ROLLERS, SHEEPSFOOT, PNEUMATIC TIRE, VIBRATORY SMOOTH-WHEEL, AND SEGMENTED-PAD AT TWO LEVELS OF EFFORT FOR EACH ROLLER, AND /5/ ROLLER COVERAGES UP TO 16. MEASUREMENTS WERE MADE INDICATIVE OF THE STRENGTH, STIFFNESS AND DENSITY OF THE SOIL USING A VARIETY OF TECHNIQUES. A FULL FACTORIAL EXPERIMENT CONSISTING OF 256 TEST SECTIONS TO REPRESENT ALL COMBINATIONS OF THESE SELECTED VARIABLES WAS DESIGNED TO DETECT, USING ANALYSIS OF VARIANCE TECHNIQUES, THE EFFECTS OF THE VARIABLES ON THE MEASURED SOIL PROPERTIES, TAKING INTO ACCOUNT THE LARGE VARIABILITY EXISTING IN THE FIELD. THE RESULTS DESCRIBE THE MEASURED CBR, PENETRATION RESISTANCE, BEARING STIFFNESS, SEISMIC VELOCITY AND DENSITY AND SHOW HOW THEY WERE AFFECTED BY THE TEST VARIABLES. THE CBR AND DENSITY ARE ALSO COMPARED WITH THE VALUES OBTAINED USING STANDARD LABORATORY TESTS. /AUTHOR/
