Dynamic Cone Penetrometer

• Portable, hand-operated equipment. • To obtain a direct evaluation of the “in-situ” strength properties of road pavement layers: the DCP has been correlated with CBR (California Bearing Ratio – Kleyn 1975). • Field calibration of a portable dynamic cone penetrometer was made to determine a penetration resistance relationship with the standard penetration resistance. • The penetrometer…
