EFFECT OF DENSITY ON MOISTURE RETENTION CHARACTERISTICS OF SOILS

THE EFFECT OF DRY BULK DENSITY OR STATE OF COMPACTION ON THE MOISTURE HOLDING PROPERTIES OF A FEW COMMONLY AVAILABLE SOILS IS EVALUATED BY OBTAINING MOISTURE-SUCTION RELATION- SHIP CURVES AT DENSITIES RANGING FROM 1.60 GM TO 1.90 GM/CC. AT SMALL VALUES OF SUCTION, THE INCREASE IN BULK DENSITY RESULTS IN REDUCED MOISTURE RETENTION CAPACITY. AT HIGH SUCTIONS WHEN THE INFLUENCE OF SMALLER PORES BECOMES MORE DOMINANT, INCREASE IN DENSITY IS ACCOMPANIED BY SMALL ACCENTUATION IN MOISTURE RETENTION CAPACITY. HOWEVER, IT IS ADVANTAGEOUS TO COMPACT A SOIL LAYER TO HIGHER DENSITIES BECAUSE OF GAIN IN BEARING CAPACITY EVEN IF THE MOISTURE RETAINED MAY BE SLIGHTLY HIGHER. /AUTHOR/
