PROCTOR VALUES FOR DIFFERENT SOILS CLASSIFICATIONS
PROCTOR VALUES FOR DIFFERENT SOILS CLASSIFICATIONS
(OP)
I WANT TO KNOW HOW MUCH PROCTOR VALUES WE CAN CONSIDER FOR DIFFERENT KINDS OF SOIL CLASSIFICATION FOR EXAMPLE
CLAYES SILT
SILTY CLAY
CLAYEY SILT TRACE GRAVEL
SILTY CLAY TRACE GRAVEL
SANDY CLAYEY SILT TRACE GRAVEL
CLAYEY SILT WITH SIZE OF 20-75MM OF GRAVEL (NATIVE SOIL)
AND MORE CLASSIFICATONS

RE: PROCTOR VALUES FOR DIFFERENT SOILS CLASSIFICATIONS
Your question is not really answerable. A moisture-density relationship (Proctor) varies even within soil classifications. It is a site-specific determination of the moisture-density relationship of THAT soil, not some other soil on some other site.
There are plenty of general references (Sowers, Lambe, and others) that give some generalizations of Proctor values with soil types, usually in a small table format; however, these are generalizations and should not be used for specific site conditions.
Also, you will have a standard Proctor being more applicable to some soils (clays, silts, etc.), while a Modified Proctor would be more appropriate to other soils (sands, gravels, etc.)
RE: PROCTOR VALUES FOR DIFFERENT SOILS CLASSIFICATIONS
Is there some legal reason for knowing general data? Are you second guessing some lab? Are you hoping to avoid paying for some lab to do this testing? There are few short cuts to this sort of testing.
I've seen a local DOT attempting to go onto a job ahead of time and run a bunch of tests on "typical soil groups" hoping to avoid having to do the proctors on the job. It didn't work.

if you want general info, trying looking in a soil mechanics book or navfac/ufc or usace or google or your local testing lab or etc etc. good luck.

I am quite sure in other geologies you could get soils that are even lighter or heavier, though I think you can also start to see a trend here that you would never expect to find soils (and I mean non-organic material) much less than 70 or 80 pcf, or much heavier than 150 to 160 pcf.
