Best Practices: For use in trail surfacing, the material should be composed of irregular angular particles that interlock and bind into a firm matrix. The rock particles should range in size from dust to 3/8 inch. Gravel and crusher fines differ from one another in that gravel is screened to remove the fines which contain the natural binders ...

Concrete strength also comes into play, but most slab concrete is around 3000 to 4000 psi, so it's not a major factor. The tensile strength of concrete is typically taken as 10 to 15% of the compressive strength, so only about 400 or 500 psi. Compare that to the tensile strength of Grade 60 rebar, which is 60,000 psi.

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.

Recycled crushed concrete can soak up more water than new concrete - as much as 9% of its weight. While water is important for the concrete to harden, too much of it can cause problems. Too much water can make the concrete crack, weaken it, and look bad. It can also cause the concrete to expand, resulting in "popouts" where cone-shaped pieces ...

Crusher-run gravel compacts well but does not drain very fast -- at least not as fast as 3/4-inch crushed stone (no fines). Talk to a soils engineer if you are worried -- but in my experience, either crusher-run gravel (compacted) or 3/4-inch crushed stone can be used under footings. So can rigid .
