I recall in the few years seeing an MR article containing info where the guy laid a gravel road using a spatula type of tool and some type of wet sticky sand/rock. I am unable to find that article. Does it ring a bell with any of you? Or does anyone have info on that method?
I use Arizona Rock & Mineral CSX/SP ballast for my gravel roads. I spread it out about ⅛” thick wet it to a consistency of mud using a 8:1 Water/White Glue mix and use a 1½ putty blade to spread and smooth it.
