Proctor testing of 3/4" clean stone
I have not seen a procter for crushed stone. Typically the stone is placed in 12-18" lifts and tamped once or twice. The stone is so much stronger than the soil and is unaffected by moisture content that lab or insitu density testing is not done. We use it in freezing weather to backfill when soil would be impossible.
