I am looking to build a paver walkway along the side of my house. I would like to build it with an open graded base as that seems to be the preferred approach nowadays. With that said, I have been to 4 masonry/landscaping supply centers in my area (Long Island to be specific) and the only open graded aggregate offered is a 3/4 inch washed bluestone. From what I gather, this stone is primarily used as a decorative top layer material. Would it still work as a paver base? It is a sandstone. Does that make a big difference? It seems limestone is more common to use for a paver base. Is that correct?
Thank you for your help.
P.S. Each supplier recommended I instead use their 3/4 inch minus RCA.
