HIGH PRESSURE LIME INJECTION

THIS SECOND INTERIM PROGRESS REPORT FOR THE STUDY DESCRIBES THE HIGH-PRESSURE INJECTION OF A LIME SLURRY INTO A HYDRAULIC FILL TO EVALUATE THE EFFECTIVENESS OF IN-PLACE LIME TREATMENT. SIX EXPERIMENTAL SECTIONS WERE STUDIED' SECTIONS 1, 2 AND 3 WERE INJECTED WITH A 0.5 PERCENT OF LIME TO DEPTHS OF 5, 10 AND 20 FEET, RESPECTIVELY; SECTIONS 4, 5 AND 6 WERE INJECTED WITH 1.5 PERCENT OF LIME TO DEPTHS OF 5, 10 AND 20 FEET, RESPECTIVELY. SAMPLINGS WERE MADE BEFORE TREATMENT AND ONE MONTH AFTER THE LIME INJECTION. DATA ARE GIVEN FOR ATTERBERG LIMITS, VOLUMETRIC SHRINKAGE, PH VALUE, CALCIUM CONTENT, MOISTURE CONTENT AND UNCONFINED COMPRESSIVE STRENGTH. IT WAS CONCLUDED THAT' /1/ THE LIME HAD BEEN SATISFACTORILY DISTRIBUTED, /2/ THERE WAS A TREND TOWARD LOWERING PI, /3/ STRENGTH WAS INCREASED LITTLE, IF ANY, AND /4/ ALL IN ALL, THE LIME TREATMENT HAD IMPROVED THE SOIL. /BPR/
