DCP vs. Compaction degree and qu vs. E correlations 1

[Okiryu]

Does anyone know references for DCP vs. Compaction degree correlations?

Also, I am looking for unconfined compression strengths from pocket penetrometer readings vs. elastic modulus correlations.

Any reference will be greatly appreciated !

Also, if anybody knows manufacturers for DCP, could you please let me know please? Thanks !

Do a search - this issue has been discussed so many times over the last 10 plus years. I would take it that you are talking the TTRL miniature (small) dynamic cone test (

https://trl.co.uk/sites/default/files/ORN8.pdf

). This uses a very small hammer. For me, dynamic cone tests can also include a 60 degree cone driven by a 140 lb SPT hammere dropping 30 inches (pentest in Canada). There is also the Mackintosh Probe, the JKR Probe, etc.

Thanks BigH...sorry, I was lazy and did not search it...Also, thanks for the links. I just sent an email to Controls-Group asking for a quote and tech information.
