How much volume is lost after compacting 3/4" crushed stone?

From my experience it depends a lot on how is the compaction done. If you are compacting road crush with a vibratory plate you will get about 10 to 15% compaction. (This is based on you having a stable compacted base first. If you are putting the road crush on top of top soil you will lose more to compaction.)
