The “binder” is the secret ingredient that will make a road last longer. As stated above sand is the most popular binder used. Fix My Gravel Road uses crushed limestone gravel with a limestone dust binder. We find that the limestone dust vs. sand binder produces a harder surface and less prone to erosion and subsequently last longer and requires less maintenance.
