The 3060 and 4080 grades of ERI’s slag products are used as seal coating surface media. The granules are shiny black and perfectly match the black asphalt color which allows for a longer “hiding” properties. The granules serve to provide physical and UV protection to the sealcoat layering. Our coal slag products are chemically inert and will withstand harsh road chemicals.
