Reducing small stone/gravel driveway movement

[snpower]

We have a driveway covered in a pea gravel type stone; it looks nice but rolls all over the place. I looked into Klingstone but the cost was way too much. We can't afford/might not want asphalt so I am looking for ideas on ways to improve adhesion/reduce movement without affecting aesthetics too much if this is even possible.

Drive slower? reduce depth (of gravel)? Can't think of much else that won't change the looks of a pretty pea gravel drive. You could add stone dust to "tie" it in, but there goes the looks. Big bucks but exposed aggregate concrete has the same look providing you order it with pea G. for the aggregate rather than crushed stone.

That type of gravel almost always moves around.
2 Things to try. Dampen the gravel and spread cement over it and sprinkle a little more. Don't soak it or wash the cement down & out.

You can also cover it with Course Sand and cement.

In both cases roll it soon after the cement has been dampened.

At best this will be a short term fix. In some places you can buy Pea Gravel that has a cement coating on it.

Best of all find a good looking 3/4" down crushed stone and work it in. Parts of my drive way have 1 or all 3 of the treatments. Best of all is the 3/4" down, Part of it has course White Sand on top, that looks the best and has held up well.

Have Fun,

All good ideas!

Question: What is an optimum depth for this material?

Clear stone will never settle entirely, unless you add a "binder" like crusher dust or something with a lot of "fines" in it. We top dress our driveway with what's called Class "A" stone here. Essentially it's 3/4 and smaller rock with the crusher fines still in it. Works great, if you add a couple inches at a time.

I agree that adding "fines" is the key. Regardless of the gravel size there must always be enough fines to support it. Of course it's the fines that usually wash away depending on the severity of the storms. Once you get enough fines and it gets packed down it will tend to wash less.

I would not suggest adding portland or cement as it will tend to break up and cause more problems "down the road". Been there done that!
