How to perform in laboratory static compaction same as proctor compaction(dynamic compaction)?
(OP)
Hi to All
I want to perform static compaction on remolded soil samples and compare the subsequent results( optimum moisture and dry density) with proctor compaction resaults using an unconfined compression test apparatus , My question is how to unify corresponding loads applied on each samples from static compaction to proctor falling hammer loads to achieve somehow same loading
I mean if the energy from proctor test for example on upper surface area of the soil is 50000 lb.ft/ft3, How much force I should put on the sample in unconfined compression test? ( probably a constant rate)
I would be grateful if you could introduce me to some of works related to my question

When properly done in the lab and properly used in the field, a Proctor is a valuable tool and works quite well. It's not perfect; however, it can be done with relatively inexpensive equipment and results are repeatable.
Many have chased the relative density route as being better. Major problems....expensive equipment, finicky test, labs won't invest in the equipment for the level of work it develops.

Put that aside, at the same time I want to prepare samples for Unconfined Compression test and If I add optimum moisture to the mixture , a question arises for me as to whether or not I compact them( it probably is required because my soil is clayey sand) and if so how in this case I could compact soil samples to reach same density as or maybe a little less than proctor, and how I could measure relative density
Do you or The Oldestguy happen to know about that?
Again Thanks a lot to you and The Oldestguy

There is a line of optimums for the Standard Proctor, the Modified Proctor, the sheepsfoot compactor, the vibratory compactor, the static compactor, the rubber tire, etc. In the lab, we find an optimum water content to attain 100 percent of the maximum dry density. Tradition claims that this is the optimum water content for 95 percent compaction also - it's not!
All we can do is our best and inform our approach using known conventions. You compact dry of, "Optimum" and you'll get better strength. Compact wet of, "Optimum" and you'll get lower permeability.
Crazy study of engineering we are into, eh?

in the above mentioned post I asked a question about Unconfined Compression and direct shear test could you suggest me some solutions or maybe a paper regarding that.

Also he ties in N value from the SPT data of borings.
