Dynamic Cone Penetrometer (DCP)
Correlations have been established between measurements with the DCP and conventional in-situ CBR so that results can be interpreted and compared with CBR specifications for pavement design.
A typical test takes only a few minutes and therefore the instrument provides a very efficient method of obtaining information which would normally require the digging of test pits.
Method of use:
The 8 kg free fall hammer is lifted and dropped through a height of 575mm. The distance of penetration of the cone tip is then recorded and the cycle repeated.
The standard kit allows continuous measurements to be made down to a depth of approx 850mm. An extension kit is available that when fitted allows works to a maximum recommended depth of 2 metres. Where sub-pavement layers have different strengths, the boundaries can be identified and the thickness determined.
Case size approx. 1100x250x150mm net weight 22kg
