What do you mean by "gravel"? Anyone involved in the road building
trades knows that gravel is a mixture of rock, sand and clay. It
forms a stable base for the road and can even form a nice dirt
Many people mistakenly use the term "gravel" when referring to crushed
stone. Do you mean crushed stone?
If so, please elaborate on your project. Is the purpose of the
crushed stone purely weed control? Is there a drainage issue that
demands crushed stone? More details please.

I suspect that is a better term. Locally gravel is nearly synonymous with
OK - under the deck is a slope that is a haven for weeds and run off from
the back of the house. I'm too tall to weed under there comfortably. So I
want to suppress the weeds, make a decent parking spot for the hose and
finally fill in the (re-dug) dry well at the walk out door. I want something
stable that the run off won't carry away when it really gets moving (about
once a year).
I suspect the original dry well stopped working when washout filled it in.
Depends upon where you live and who is involved in the road building
trades and what kind of roads you are building, I guess, John.
My bother-in-law is a sales manager for Norris Aggregates. They sell
millions of tons of gravel or crushed stone for roads and concrete and
all sorts of construction projects.
My son owns a truck and hauls gravel, or crushed stone, as you call
it. He is currently involved in hauling 3 inch base rock for the
access raods to a wind farm being constructed in the area. This is
laid directly upon the subgrade.
After the 3 inch base is laid and compacted, they will overlay with
1 1/2 inch rock.
No sand, No clay. Just gravel, rock, crushed stone.... same stuff.
They then have a road.... capable of supporting the extremely heavy
loads, of tower, blade, turbine and control components that will be
transported over these roads.
No mix of sand gravel and clay.
Perhaps you were thinking of concrete? If so, it is a mixture of
cement, gravel (crushed stone) and water and whatever specialty
additives necessary for the project requirements?
Son also hauls sand to one of the local ready mix plants. He doesn't
haul if there has been rain enough to cause any mud on the access road
as any mud buildup on his truck frame that falls into the dump area
has the potential to ruin the mix.
Any clay in the mixture will ruin it and the load will be rejected.
Perhaps things are done differently in your area, I can't speak for
that, buth then again you cannot speak for all inclusively about
Once again, here is a basic primer on gravel:
Should you desire more information, I am sure Bill (the Bro-in-Law)
will be happy to forward me what he knows.
I can also have my son request information from a classmate of his who
is now general manager for **** Construction, KC division, a family
held business that contracts all over the state of Missouri.
Perhaps you meant a sand-clay road.
Ouch, be more careful, that's gotta hurt, John
4 years ago I had a load of pea gravel left over from a drainage job,
so I used it as a surface mulch laid direct on weedfree soil, no
barrier, on a bed planted with herbaceous perennials. It's about 3"
deep. Four years on, the gravel still looks good and clean, and very
few weeds manage to germinate in it (easily tweaked out.). Pea gravel
is the size of peas.

Several inches to a foot or so, depending on how well it packs (I
assume you're talking something like pea gravel).
However, as the surface collects "soil" from detritus blowing in and/or
rotting, you'll form more pockets that will allow seeds to germinate.
Will you be mowing near your gravel? In my experience, there's no such thing
as truly contained gravel. And gravel slung by lawnmower blades is
a lot tougher on both the blades and on the thing the gravel hits than
an organic mulch of some flavor.
Dry lawn clippings make great mulch that needs to be renewed once a year
or so... much less work than gravel. Just make sure the clippings come from
plants not recently treated with herbicide.
