Abstract
THE RELATION BETWEEN THE COMPOSITION OF A SOIL AND THE VALUE OF ITS ATTERBERG LIMITS IS SHOWN ALONG WITH THE NEED FOR DETERMINING THESE LIMITS WITH MORE ACCURACY. THE USE OF THE CONE PENETROMETER CAN ADVANTAGEOUSLY REPLACE THE CUP METHOD FOR DETERMINING THE LIQUID LIMIT, BUT SHOULD NOT BE APPLIED TO THE DETERMINATION OF THE PLASTIC LIMIT. IT IS PROPOSED TO USE AN 80-GRAM CONE WITH A 30 DEGREE ANGLE AT THE SUMMIT TO DETERMINE THE LIQUID LIMIT, WHICH IS DEFINED AS THE MOISTURE CONTENT AT WHICH THIS CONE SINKS TO A DEPTH OF 17 MM UNDER ITS OWN WEIGHT. /LCPC/A/TRRL/
