I am currently testing surface coarse material for a road in Montana. The original material to be used had no PI. It was decided to add bentonite to give the material a PI of up to 7 +-3. Everyone who tests this material gets different answers ranging from 0 to 16. This is the first time I am testing bentonite. I know it is very finicky. Because everyone is getting conflicting Atterberg results, I was wondering if there is a better way to test bentonite mix soils? I heard of a cone drop/penetration test. I just want a more accurate answer so that we can figure out which tester is the most accurate.
