compaction factor of stone aggregate

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 100% without talking about your subgrade. If the subgrade is sandy, it will not invade such a well graded gravel as much. This is a superior situation.

A number of websites have recommended adding 4% to the order to account for compaction. Bob Vila Gravel Expert Great Day Improvements最佳答案 1When something calls for x" of compacted y, you typically calculate the amount of y prior to compacting. So if something calls for a 4" compacted...3From my experience it depends a lot on how is the compaction done.

2008-06-24  I think relative compaction on open-graded aggregate is stupid. There is no "Proctor curve" to go by either. There may be some benefit to doing relative density, but I don't have much experience with that other then to know that you need a vibratory table to

2011-10-04  No. 57 stone is an easily consolidated material but it is not self-consolidating. Uncompacted or dumper deposits of No. 57 stone can settle about 1″ per foot of thickness. No. 57 stone should be placed in lifts and consolidated using conventional compaction techniques. It is very obvious when the stone is consolidated and locked into place ...

2003-04-29  Re: Self-Compacting 3/4quot; stone The crushed rock I was referring to, is, in my area, like a red quartzite, and it is still sorted and washed according to size and to remove fines. The larger the rock, the more reservoir capacity as far as drainage, because of more opens in the aggregate. 3/8 pea rock is the product of choice around here for AWWF footings, and 50% backfill.
