Developed by the Army Corps of Engineers, Dynamic Cone Penetrometer Kits (DCPs) provide a low-cost, efficient test method for quickly determining in-situ CBR values of pavement base, subbase and subgrades. Dynamic core penetrometers can readily be used for depths up to 30" and up to 6' with optional drive rods and extensions. This model 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. Dynamic core penetrometers cover a CBR range from <.05 to 100% and a bearing value range from 430 to 10,800 psf.
Standard Dynamic Cone Penetrometer Kits
The Standard Dynamic Cone Penetrometer Kit measures the shear strength of soil with a CBR between 0.5-100% and from 430 to 10,800 psf. This single-operator kit is ideal for state/county/city highway departments and geotech firms. CBR and psf can be estimated in the field from tables in the manual and plotted using Corps of Engineers Excel template included on CD. It comes with a stainless steel dual-mass (17.6/10.1 lb) hammer and quick-connect upper rod, 30-inch drive rod (27-1/4 inch penetration), a 40-inch vertical scale, upper and lower scale mounts, a reusable hardened point and a disposable cone adapter with 25 disposable cones for fast and easy extraction of the instrument from hard/cohesive soil. The dynamic cone penetrometer kit also includes a crush-proof Pelican carrying case with transport wheels and wrench set.
