But none are "paved" in the usual sense of that word. I would hate to drive on a "fine gravel" road, or an ice road, unless I was prepared for it. Even if the fine gravel were on top of a compacted substrate it would present a hazard to bicycles and motorcycles. I'm not sure I care how a "salt" road is classified - I've never seen one let alone driven on one.
