    Where I live, which is the Netherlands, most highways are made of this stuff. It's great, no spray and much more grip when it's raining. Much safer. They're kinda problematic too though, they get clogged with dirt and when it then freezes after rain it'll crack the road. edit; the stones are set in a rubber sort of material so it can stretch and compress with the freezing water to some extent. Salting the roads and thus making sure they don't freeze and the water can run off helps a lot.
