FOR A ROUGH ESTIMATE ON DIRT USE 1.5
SQUARE FEET X DEPTH X WEIGHT(1.5) WILL GIVE YOU THE YARDAGE NEEDED FOR YOUR FILL. THIS IS ROUGH BUT SHOUDL GET YOU CLOSE.
I.E. A 10 BY 10 PAD WITH 5 FEET OF FILL
100 X 5= 500 X 1.5 = 750 YARDS OF DIRT
PS- AB/AC USE 2.
I HAVE USED PULVERIZED AC AS A BASE MATERIAL BEFORE. THE GRINDER SHOULD PULVERIZE THE MATERIAL TO AN AVERAGE OF 3/4 INCH. YOU MAY HAVE SOME CHUNKS, AND IT WOULD BE A GOOD IDEA TO USE AN 815 FOR COMPACTION BEFORE THE SMOOTH DRUM ROLLER.
