When compacting soil, you do it in 6" lifts. What about compacting washed gravel or crushed rock? I was told that # 57 gravel is self compacting. I find this hard to believe. I want to be dang sure.
What do you do? What has been your experience. Anyone here have the answer. Thanks
The situation is filling a 3' wide x 7' deep ditch that will have concrete paving over it.
