SOIL STABILIZATION

ASPECTS OF SOIL STABILIZATION WITH LIME ARE DISCUSSED. THE EFFECT OF LIME DEPENDS ON THE CHARACTERISTICS OF THE SOIL TO BE TREATED AND, TO A LESSER EXTENT, ON THE PURPOSE OF THE TREATMENT. LIME IS GENERALLY USED TO STABILIZE FINE- GRAINED SOILS BY ADDITION OF 3--8% LIME BY WEIGHT. WHEN ADDED TO PLASTIC SOLS, IT GENERALLY REDUCES PLASTICITY AND INCREASES FIRABILITY, THUS IMPROVING WORKABILITY. LIME ALSO CHANGES COMPACTION CHARACTERISTICS, GENERALLY BY DECREASING MAXIMUM DRY DENSITY 2--5 LB/CU FT AND INCREASING OPTIMUM MOISTURE 1--5%. LIME HELPS SWELLING SOILS BY REDUCING EXPANSION AND SHRINKAGE AND FORMING A BARRIER TO KEEP EXCESS WATER FROM REACHING UNTREATED SUBSOILS. EFFECTS OF LIME ON STRENGTH CHARACTERISTICS ARE SHOWN GRAPHICALLY. THE RATE OF STRENGTH GAIN INCREASES WITH INCREASING TEMPERATURE. CURING TIME IS OF GREAT IMPORTANCE IN HIS REGARD. LIME CONTENT DETERMINATIONS WITH AND WITHOUT A PH TEST ARE DESCRIBED. INJECTION METHODS ARE NOTED BRIEFLY.
