RAPID DETERMINATION OF CBR WITH THE PORTABLE CONE PENETROMETER

A LIGHT INEXPENSIVE PORTABLE DYNAMIC CONE PENETROMETER IS SUGGESTED AS A VALUABLE TOOL FOR THE RAPID DETERMINATION OF IN-SITU CBR IN THE RANGE OF 1.50. VARIOUS CONE PENETROMETERS HAVE BEEN INVESTIGATED. THE DYNAMIC CONE PENETROMETER IS A MODIFIED AND SIMPLIFIED VERSION OF THE PENETROMETER USED BY THE COUNTRY ROADS BOARD, AUSTRALIA, AND CAN BE USED DOWN TO A DEPTH OF 1 METER. A 3MM MODEL IS ALSO AVAILABLE. USES OF THE DCP INCLUDE THE DETERMINATION OF ROAD FOUNDATION CBR AND THE DETECTION OF SOFT PATCHES OR HOLLOWS IN EARTH FILLS OR UNDER FIXED OBJECTS LIKE AN EXISTING FOOTING. IT CAN ALSO BE USED IN CONJUNCTION WITH A HAND AUGER AS A USEFUL TOOL FOR QUICK TERRAIN EVALUATION. /A/RRL/
