BENEFICIATION OF LOW GRADE SOILS. PART 1: LIME STABILIZATION OF PUERTO RICO LOW GRADE SOILS

SEVEN PRINCIPAL SOILS WERE TESTED FROM EXTENSIVE CLAY CONCENTRATIONS IN THE EAST AND WEST SIDES OF THE ISLAND OF PUERTO RICO. WITH THE EXCEPTION OF THE DUEY SOIL, ALL OF THE SOILS WERE OF A LOW-GRADE, HIGHLY PLASTIC VARIETY. ALL SOILS IMPROVED WITH THE ADDITION OF LIME. PLASTICITY INDEX IMPROVEMENT WAS NOTED, ALTHOUGH THIS CHANGE WAS MORE PRONOUNCED UNDER THE EFFECT OF CURING. DENSITY SHOWED A TENDENCY TO DROP WITH THE ADDITION OF LIME ON THE TESTED SOILS. THE CALIFORNIA BEARING RATIO INDICATED VARIABLE RESULTS, WITH INCREASE ASSOCIATED TO MAXIMUM VALUES ON THE BEARING RESULTS. A SIMILAR SITUATION WAS FOUND WITH THE COMPRESSIVE STRENGTH. CURING TIME IS AN IMPORTANT PHASE IN ANY TYPE OF LIME TREATMENT. DUE TO VALUES OBTAINED IN THE BEARING CAPACITY TEST, IT IS CONSIDERED IMPORTANT THAT CAREFUL STUDIES OF SOILS TO BE STABILIZED BE CONDUCTED PRIOR AND DURING THE ACTUAL CONSTRUCTION. THE LONG-RANGE BEHAVIOR OF THE MIXES MUST BE STUDIED CAREFULLY. SINCE EVIDENCE OF FURTHER CHANGE WITH TIME WAS NOTED.
