no clue. . . If you want to know bank to compacted though, take your sand cone or nuke gauge to the pit, get the dry density in situ, contrast that to the appropriate proctor density (let's say it's at 92 percent relative compaction in situ) and assess how that relates to the specified compaction requirement (let's say that's 95 percent).
I think you could handle the calculation from there. . .
