Dynamic Cone Penetration (DCP) testing is used to measure the strength of in-situ soil and the thickness and location of subsurface soil layers. It is similar to CPT (cone penetration testing) in that a metal cone is advanced into the ground to continuously characterize soil behavior.
How do you calculate DCP?
The DCP index is based on the average penetration depth resulting from one blow of the 17.6 lb (8 kg) hammer. The average penetration per hammer blow of the 10.1 lb (4.6 kg) hammer must be multiplied by 2 in order to obtain the DCP index value from the correlation equation in paragraph 4.
What is DCP test in road construction?
The Dynamic Cone Penetration Test provides a measure of a material’s in-situ resistance to penetration. The test is performed by driving a metal cone into the ground by repeated striking it with a 17.6 lb (8 Kg)weight dropped from a distance of 2.26 feet (575 mm).
How do you carry out a DCP test?
Conducting a DCP test involves raising and dropping the hammer to drive the cone on the lower shaft through the underlying pavement layers. Typically, after each hammer blow, the penetration of the cone is measured and recorded. In stiffer soils, readings may be recorded after several hammer blows.
What are the advantages of DCP?
Benefits of DCP One can collect information from a lot of points relatively quickly, so you can see how soil conditions vary across the site and respond accordingly. One gets accurate and precise information on the soil conditions in the field and at construction time.
Why is DCP test done?
DCP testing is used to determine the strength of the subsurface and design load of the soil. The engineers perform the testing in-situ to give an estimation of the load bearing capacity which a soil can withstand, by measuring the extent of penetration into the ground of a calibrated tip or cone.
What does DCP stand for?

How do you run a DCP test?
Why DCP test is done?
What is CBR value?
The California Bearing Ratio (CBR) is a measure of the strength of the subgrade of a road or other paved area, and of the materials used in its construction. The ratio is measured using a standardized penetration test first developed by the California Division of Highways for highway engineering.
What is DCP medical?
2,4-DCP: A poisonous chemical used to produce a herbicide. 2,4-DCP (short for 2,4-dichlorophenol) is employed in the manufacture of the herbicide 2,4-D (which is short for 2,4-dichloropheoxyacetic acid). There is no known antidote to 2,4-DCP poisoning.
