DCP testing can obtain CBR values on your subgrade and formation material and because it's small, lightweight and requires no reaction load or dead-weight it is perfect for:
CBR values on a site where you have no plant to act as a reaction load
CBR values where the test area is inaccessible to a 4 x 4 vehicle for Insitu CBR by the traditional plunger method
The Dynamic Cone Penetrometer (DCP) is an instrument designed for the rapid in-situ measurement of the structural properties of existing road pavements constructed of unbound materials. The robust and simple design means that the DCP is quick and easy to use, portable, and suitable for use in locations where access may be difficult. It is commonly used to determine a California Bearing Ratio (CBR) profile for pavement design.
Highways England compliant apparatus
Quick and fuss free
UKAS accredited test
A note of Caution for DCP Testing
Whist it's quick and easy it provides only an approximate assessment of CBR.
As the device is ground penetrating a full utilities survey is required beforehand.
Minimal access required but should only be selected when no other method is viable.
