Here at Richard Jackson Ltd, we have recently taken delivery of a dynamic cone penetrometer (DCP) for use on our Client’s sites. The equipment can be used to assess the in-situ properties of existing road pavements which are constructed with unbound materials and soils encountered in shallow pits. Using established correlations, an assessment of California Bearing Ratio (CBR) can also be made quickly following completion of the probing.
We have recently used the DCP for rapid assessment of soil properties beneath a proposed heli-pad! As well as parking areas and roads. Using the DCP has assisted in rapidly speeding up the design process. As well as being easy to use, the equipment is robust and portable, it is also capable of probing to depths of up to 1.5m below ground level.
The DCP provides an economical alternative to conventional laboratory testing and in-situ CBR testing whilst informing the design process.
