Dynamic Conical Penetrometer- DCP results can be compared and interpreted with CBR (California Transport Rate) according to Kleyn 1982 studies.
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 in that a metal cone is advanced into the ground to continuously characterize soil behavior. The resulting downward movement is then measured.
Continuous measurements can be made to a depth of approximately 800 mm, or it is recommended to make a maximum depth of 2 m when using extension rods.
