crusher run compaction

May 17, 2006 2 Replies

I'm about to order stone for a paver installation. I plan to follow the recommended specifications for my area which is a 4 inch gravel base.



I want to use crusher run. Does anyone have any comments about the amoutn of compaction that will occur. I am asking because I assume that 4 inches of stone will compact down to some degree.



I am looking for an overage rule of thumb.



The compaction will be minimal as the material has little air space when spread. If you need a number, add an inch to your intention. If you plan on 4 inch, compute for 5 inch. Calculate for the cubic yardage required and multiply the result by 1.25 for tonnage.

Average coverage of 50 sq ft per ton at a 4" depth compacted. Most loose gravels cover more like 60 sq ft / ton 4" deep.
