Dynamic Cone Penetrometer Test Results - Correlation to 'k'

Dynamic Cone Penetrometer Test Results - Correlation to 'k'

Dynamic Cone Penetrometer Test Results - Correlation to 'k'

(OP)
Hi,
Can anyone help me with correlating the results of TRL DCP testing with modulus of subgrade reaction, 'k' please?

I have found correlation to CBR, and from there I can get to 'k', but haven't found a direct correlation yet.  

Thanks

Before anyone responds, please identify your dynamic cone details. Is this the TRRL miniature cone or the Sowers cone or the Canadian pentest. There are many varieties of dynamic cones.

Thanks BigH

I've checked,  It's the UK TRL DCP - 8kg weight dropping 575mm onto a 60 degree cone, 20mm diameter.
