I will try to do a little research.
In my experience of having to deal with quite a bit of the stuff, It is 'neither fish nor fowl' and I have been constantly fooled as to how it will behave. I wish I never met it. I much rather deal with the Silty Clay, CL-ML (I also have a lot of it) which the literature also avoids like the plague.
How's about adding to this another factor to think about and reason why.
Take the case of large rubber tired equipment like self propelled scrapers. Why does the ground deflect down and then spring back up as they pass? Seems to happen on many types of soil. There even are "specs" that want to see a litttle of this at acceptance density.
