The Pavement Dynamic Cone Penetrometer (DCP) is a very robust instrument, designed for rapid in-situ evaluation of strength of sub- grade and the bases for roads & runway pavements. Continuous measurements can be made down to a depth of 800 mm, or when an extension is fitted, to a depth of 1200 mm. Where pavement layers have different strengths, the boundaries can be identified and the thickness of the layers determined.
