Is it:
bank dry density / compacted dry density
or
compacted dry density / bank dry density
I have a couple of sources that say bdd/cdd and I have one that says cdd/bdd*.
Just in common sense terms, shrinkage factors are typically 0.8-1.0, and for soil, compacted dry density is going to be higher bank dry density, so using typical shrinkage factors of <1, the compacted dry density should be in the denominator and bdd/cdd should be correct.
*the one source is the new construction afternoon depth reference that came out this summer.
