Dynamic Cone Penetrometer
The most widely accepted, portable method for evaluating strength and density of soil. The dynamic cone penetrometer uses a 15 lb. (6.8 kg) drive mass falling 20 in. (50.8 cm) that strikes the anvil to cause penetration of 1.5 in (3.8 cm) diameter cone (45° vertex angle) that has been seated in the bottom of a pre-augered hole. The blows required to drive the embedded cone a depth of 1-3/4” have been correlated by others to N values derived from the Standard Penetration Test (SPT). Experience has shown effectiveness in pre-augered holes to depths of 15’ - 20’ (4.6 to 6.1 cm). The cone can be replaced with a plated drive tube assemble for collection of 3” x 10” (7.6 x 25.4 cm) samples in pre-augured holes.
