The PolyPavement sounds like a good idea and I actually had a bookmatk on the same website. I'll start a new post to see if any others have had luck and their experience with this product.

It's been done many times. Topsoil is stripped away. Portland cement is spread and rototilled into the gravel. It is then tamped down with a plate compactor or roller. Moisture is absorbed from the soil and it sets. One bag of portland cement (94 pounds) is exactly one cubic foot. If you know how deep your tiller tills you can calculate the ratio. It's been a while, so offhand I don't know the optimum ratio, but you can research rammed earth and get information.

sounds rough on a tiller to me.
could you go back over an existing gravel driveway,
box blade off the larger rocks and till in the cement?
then compact it by driving over it?

I have a steep part of my driveway that does not pack down. I'm looking at option to make it more "packable". It currently has creek gravel on it. I plan to top dress with crushed limestone one was get the building done. Can I just spread a couple bags of portland cement on that to help it pack?

You can't just spread Portland and have it do much of anything. You need to mix it into your gravel or native soils, then wet, grade, and compact.

It is not hard on the tiller if you use the right sized tiller.
But having done a lot of road reclamation over the years i can't recommend adding any Portland cement to your road. For a concrete mix to work you mix the proper proportions of clean hard stone aggregate with the right amount of clean (washed) sand withe the cement and just enough water to make it mixable . Your driveway material is dirty dirty DIRTY!!!. It will make a lousy concrete.
Show us some pictures of your drive and tell us what you want it to be and how much you can spend on it and we can give you some good ideas about how to get the most out of that money.

You only have creek rock down right? So it's a clean rock. If so then add a crusher run rock like 610's. Something with dust so it will compact.

If you want to make "soil concrete" be ready to put down more than a bag or two. ;-)
It is good stuff, but that does not mean you can get by with 1/10th the cement to make the concrete.
Add to that, if you have freeze thaw cycles (read "winter") the soil concrete will break up.
What ever happened to "oil roads"? They worked so well....... ;-)

Around here you can get "limestone sand" that will pack down VERY tight and becomes nearly like concrete once it has been wet and has dried. Problem is it is only that way when dry without something else to help hold it. If you have a good base of mixed stone down, putting a liberal coating of limestone sand across it and letting it settle in and pack in will lock those rock tight wet or dry.
As with anything; on a hillside with water, it is going to succumb eventually. But for a gravel type drive in those conditions that's my best advise.

Yes just have creek rock. I also think the reason it doesn't pack now is #1 it's on a grade, #2, there are a lot of large stones in there. I'm going to try to get some off the bigger stuff out of it, drag it with the box blade then get a load of crusher run and see what happens. I will take a photo next time I'm out there.
