1. coarse grained, fine grained, highly organic
2. static, dynamic, ?...rolling, ramming, vibrating (sounds dirty)
3. soil density is being increased by elimination of air and optimization of particulate cohesion
4. depends what you're testing for. hand sqeezing will reveal some things while dissolving the soil in a clear jar full of water and allowing it to settle out over time will reveal other properties.

Ladies and gentlemen I think we have a winner!!

speaking of compaction, in trenches, what are you guys using? we use an excavator mounted sheepsfoot for most of our cohesives....and excavator mounted vibratory plate for granular or cohesive that is 4%+ over optimum moisture.

why the shaker-head for wet cohesives?

dayexco

our type of clay here, anything over optimum, it's like trying to roll bubble gum, can't keep the wheel clean
