Spreading gravel

We have base rock, finest crushed stone. Also 3/4" crushed rock. Is crusher run a particular size? Thanks

Crushed stone: this is generally limestone or dolomite that has been crushed and graded by screens to certain size classes. It is widely used in concrete and as a surfacing for roads and driveways, sometimes with tar applied over it. Crushed stone may also be made from granite and other rocks. A special type of limestone crushed stone is dense grade aggregate, or DGA, also known as crusher run. This is a mixed grade of mostly small crushed stone in a matrix of crushed limestone powder.

And when it gets damp, clumps together as was described earlier in the thread. If the 'clump' is in the front of the 'trailer'.......when it breaks loose and slides.......s**t will happen, guaranteed.

"Crusher run is a mixture of many sizes of stone from about 1" to 1 1/2" down to dust." This statement matches my purchases.

Only if it sets on the trailer for 6 weeks and there is 10" of rain.

Just a matter of terminology but stone that is "run through a crusher" is fragmented. It is available in various sizes but is always fragmented with fractured edges. This fractured surface will pack much tighter than smooth stream bed gravel. The base course I use the most in my area is 3/4" to fines, which is supposed to have up to 3/4" crushed rock and smaller with enough fines to pack this down. Most of this starts out as larger stone that is crushed and graded according to the size needed.

I would suspect that your base rock is a mixture of larger stones and fines to put down first, the finest crushed stone is likely an engineered fill and the 3/4" crushed rock is clean rock without the fines. A crusher can produce all of these when "running".

If that's what you want to believe.

And it's the 'fines' that cause the problems(especially), in trailers.
Contrary to popular assumption, this stuff is not stored inside.........it's outside in the elements........rain, snow, sun, freeze, thaw. Then you get the nice trip down the bumpy roads...........compacting the load.......can get interesting when dumping.

EDIT: Steve, this was not directed at you........you just described 'crusher run' the best.

Thanks. Our stone comes from a local Quarry and all goes through a crusher.
Our base rock is ALL very fine !

I like crusher run for driveways/lanes because of the fines, which once packed act as a sort of glue to hold everything together even on a mild slope in a hard rain. After it's well packed and driven on a while, it's friendly to foot traffic, too. I got some larger stuff once, 2"-3", and although it worked ok my wife hated it because she just about couldn't walk on it in sneakers without rolling an ankle, and couldn't walk on it at all with any type of heels on. Didn't do that again..
