A METHOD OF DETERMINING SWELL POTENTIAL OF AN EXPANSIVE CLAY

THE USE OF THE ONE-DIMENSIONAL CONSOLIDOMETER TEST IS DEVELOPED AS A METHOD FOR DETERMINING THE SWELL CHARACTERISTICS OF AN EXPANSIVE SUBGRADE SOIL AND FOR PREDICTING ITS SWELL POTENTIAL. IT WAS SPECIFICALLY APPLIED TO A STIFF, FISSURED CLAY SHALE WHICH SERVES AS SUBGRADE FOR INTERSTATE 70 NORTHWEST OF LIMON, COLORADO. IT WAS NECESSARY TO DESIGN NEW SAMPLING EQUIPMENT TO OBTAIN SATISFACTORY CONSOLIDOMETER TEST SAMPLES IN THIS HARD, FISSURED MATERIAL. THE SAMPLER DESIGNED CONTAINS A SERIES OF LINERS, WHICH ENABLE THE TEST SPECIMENS TO REMAIN CONFINED IN LINEAR RINGS FROM TIME OF FIELD SAMPLING UNTIL THE CONSOLIDO-METER TEST IS COMPLETED IN THE LABORATORY. EACH INDIVIDUAL LINER RING HAS THE SAME HEIGHT AS THE DIAMETRICALLY ENLARGED CONSOLIDO- METER RING INTO WHICH IT IS FITTED. COMPLETE LATERAL CONFINEMENT IS THUS MAINTAINED ON THE SPECIMENS DURING THE SAMPLING AND TESTING WHICH PREVENTS STRESS RELIEF ACCOMPANIED BY PREMATURE EXPANSION DURING TRANSFER OF THE SAMPLE INTO THE CONSOLIDOMETER.
