Replacement for Granular Proctor?
Replacement for Granular Proctor?
(OP)
I've been out of the materials testing business for a few decades now and I am wondering if new research has been done to replace the Proctor lab test for granular soil compaction. I seem to recall a maximum density shake table type test but never saw it widely adopted. Anything new out there?

RE: Replacement for Granular Proctor?
The maximum density "shake" table you mention has been around for at least 50 years, but the procedure gives you a relative density value rather than a comparative, correlated lab standard for field comparison....stick with the Proctor.

ASCE is using a Proctor test as a student competition for our regional meeting.
It's a tribute to those who developed the core tests of our profession (Proctor, Casagrande, etc.) that these tests are still core to geotechnical practice.
