A dynamic cone penetrometer (DCP) is a tool used for evaluating the strength of soils on-site. It also helps with monitoring the condition of granular layers and subgrade soils in pavement sections over time. It can be used to determine the right solutions for the sites, especially when soft soils are involved.
The DCP uses a 15-pound steel mass falling 20 inches to strike an anvil deeper into a hand-augured hole. Count the number of blows needed to drive the anvil down 6-inch increments.
