Patio paver sub-base

Hi all, I have a quick question about the materials used for the sub-base of a paver patio. I have access to a large amount of white decorative stone that is about 3/4 to an inch. I was wondering if that could be used instead of gravel. I was thinking of tamping it down and then laying sand on top to fill any gaps. Good idea or bad idea? Thanks for any info.

Very bad idea.
It's not compactable.

Is it necessary to raise the height that much? I would just compact whatever is there & lay the mix on top of that. The mix being 3 sand to 1 Portland. Then the pavers.

I assume you are talking about pea gravel. White stones that are rounded. As Joecaption said it's a very bad idea. It does not compact to form a solid base. The rounded shapes, even with sand added to fill the gaps, will just roll around.

Thanks everyone. I kind of thought the same but I thought that I would double check. I just have a lot of these decorative stone that I was hoping to get rid of. They look nice when first placed down in the yard but then become a real pita when you go to cut the lawn. They wind up all over the place. I will never use stone as a border again. Thanks again for the info.

We like using the decorative stones but you must use edging to keep them out of the grass and for trimming. You can buy plastic edging or like us, use wine bottles. i have a bulb auger that I use on the end of my cordless drill that works great for setting the wine bottles. If you don't drink wine use any type of glass bottle!
