B046 road subgrade DCP dynamic cone penetrometer

Road subgrade DCP dynamic cone penetrometer

Dynamic Cone Penetrometers (DCP) provide quick field determinations of soil shear strengths at depths up to 6ft (1.8m), with optional extensions. This accurate and portable field equipment measures soil properties that can be related to CBR or Resilient Modulus laboratory values. Original design by United States Army Corps of Engineers meets ASTM requirements. The DCP bridges the gap between laboratory pavement design and construction quality assurance.

Penetration resistance from the sliding hammer is measured in blows per millimeter. Cone diameter of the point is larger than the rod to ensure driving energy is not lost to skin friction on the rods. The driven points are available as multi-use Hardened Steel or single-use Disposable Cones. The Disposable Cones are abandoned in place and often used when points would be difficult to extract. Both cones have a maximum diameter of 0.790in (20.1mm) tapering at a 60° angle to a point. Rods assemble easily with quick-connect pin fittings and can be driven to a depth of about 28¼ in (71.8cm). Optional extension rods with threaded connections can be purchased separately for testing to greater depths.

 Dynamic Cone Penetrometer measures shear strength in soils with CBR values from 10 to 100. This kit is ideal for occasional use in areas where very weak soils are not common. The single-mass 8kg (17.6lb) structural steel hammer is standard. 2" depth rings are marked on the 30in (76.2cm) Drive Rod. Also included is one SFA-22 hardened point, manual & CD, and 3-in-1 oil. The Manual provides look-up tables for to correlate blow counts with CBR and unit weight values. The SF-10 is not supplied with a field carrying case. Disposable cones, Adapters, and additional Hardened Points, are sold separately.
