How much volume is lost after compacting 3/4 crushed

With a more properly graded 3/4 washed stone (such as a good filter stone ranging between the 3/8 and 1 diameter) you will have a loose drop of more like 75% but you will also actually be able to get closer to without talking about your subgrade If the subgrade is sandy it will not invade such a well graded gravel Get price
