Dynamic Cone Penetrometer (DCP)
Dynamic Cone Penetrometer
The Dynamic Cone Penetrometer (DCP) is a portable field testing device used to evaluate the strength and compaction of soil subgrades and granular layers. Designed for quick and direct measurements, it enables engineers to assess soil resistance by measuring penetration depth with each drop of a standard rammer.
The test can typically be completed in minutes and provides results equivalent to more time-consuming methods like test pits—making it ideal for rapid on-site evaluations in road construction and geotechnical investigations.
