You will probably get more and BETTER answers if you post some pictures on what your drive is like now

I'll try to get some pictures and post them. Thanks for the idea.

Egon thanks for a voice of experience.

Streetcar, Thanks. Good information.

I used crusher run earlier this year and was very pleased how it set up almost like concrete. Tough stuff... 400 a load here.

Thanks for the info. Your experience is very helpful.

With truck weight take into account wet or dry.

Also note that compactability depends on size distribution of the crushed aggregate. This in turn will depend on rock material and crusher settings.

For Government prodjects the grading of the crushed gravel may have to be adjusted by screening and/or mixing of different crushed sources.

For proper compaction there are a lot of variants involved.

I've been thinking of top coating my driveway with crusher dust. Like it's been said; it packs down like cement. However, I do hear complaints that it tracks in the house. Opinions/ experience with this?

When I relocated our driveway ten years ago I initially put down geo-tex (after removing all topsoil), then a layer of 1's and 2's, then topped it with crusher run.

It has held up extremely well, and it does pack down/dry up like concrete.

Haven't had much in the way of problems with it getting tracked inside the house, but we still have some asphalt right near the house.

When we had linoleum in the kitchen we did have a problem with it eventually becoming discolored from the asphalt.

Generally, the well built driveway is graded so water runs to the side of the drive and never crosses it. The surface has to be maintained so the water does not run parallel and for ruts.

If you are building new, then the typical drive is built with a base of coarse material with a finer product on top. The thicknesses of the layers depends on what below it. Black dirt must be removed or you'll never have a good drive. If you have a clay that's prone to pumping then the base layer could be as thick as 12-16" with a layer of fabric to help prevent the pumping. Personally, I've tried to cut deep enough to get down to the natural gravel that we have around here and the build back up. The ensures the driveway does not become soft when the frost comes out in spring. Frost will drive the particles apart resulting in a quicksand like surface. If the road is dry then frost will have little water to freeze.

For the driving surface, I use 3/4 to 1-1/4" road gravel, also known as "traffic bond". This is a crushed stone of the size listed with finer stone, sand a clay blended in to help lock the larger material. The larger the stone, better it will support a load and the less likely it will wash out.

"Breaker run" is the second cheapest material a quarry can sell as it is ungraded. It's good for coarse fill, but much else. I've had really good luck in the past using 3" TB for the base and the 1-1/4" TB for the driving surface.
