A NEW METHOD OF DETERMINING LIQUID LIMIT OF SOILS

TESTS FOR DETERMINING THE LIQUID LIMIT OF SOILS ARE REVIEWED. LIQUID LIMIT TESTS GIVE THE MOISTURE CONTENT AT WHICH THE SOILS PASSES FROM THE PLASTIC TO THE LIQUID STATE AND IS THE STATE IN WHICH THE SOIL HAS LOST PRACTICALLY ALL ITS STRENGTH. THE LIQUID LIMIT OF SOILS GENERALLY INCREASES WITH INCREASE IN CLAY CONTENT. A CONE-PENETROMETER WAS EVOLVED FOR DETERMINING THE LIQUID LIMIT OF SOILS WITH A FAIRLY WIDE RANGE. THE CONE HAS A HALF ANGLE OF 15 DEGREES 30 MINUTES AND PENETRATES TO A DEPTH OF ONE INCH UNDER A LOAD OF 148 GRAMS WHEN THE SOILS ARE AT LIQUID LIMIT. A LARGE NUMBER OF SOILS WITH WIDE RANGE OF LIQUID LIMITS WERE DETERMINED BOTH BY CASAGRANDE'S MECHANICAL DEVICE AND THE PROPOSED PENETROMETER. RESULTS SHOW THAT THE CONE PENETROMETER GIVES MORE CONSISTENT RESULTS FOR A WIDER RANGE OF SOILS ESPECIALLY TOWARD THE SANDY SIDE WHEN COMPARED TO THE MECHANICAL DEVICE.
