Dual Mass Dynamic Cone Penetrometer with Quick-Connect End

Dynamic Cone Penetrometers (DCPs) quickly determine in-situ CBR values of pavement base, sub base and sub grades. They are primarily used to determine in-place soil shear strength in road construction with CBR values from less than 0.5 to 100% and bearing values ranging from 430 to 10,800 psf.

They can be used for depths to 6 ft with optional rods and extensions. The DCP complies with ASTM D6951 specifications and comes with a chart to compute CBR values, as well as an Excel spreadsheet template, which automatically charts the test results.

The Dynamic Cone Penetrometer consists of a drive hammer and steel extension shaft assembly with a 60° hardened cone tip attached at one end. The cone tip is driven into the pavement or sub grade by means of a sliding dual-mass hammer. The diameter at the base of the cone is 20 millimeters, which is 8 millimeters larger than that of the extension shaft. The DCP can also quickly convert to a single- mass unit for use in weaker soils having low CBR values or foundation evaluations by removing the outer sleeve from the dual-mass hammer.
