Mineral fillers make up less than 6 percent of the hot mix asphalt concrete by mass, and generally less than about 3 percent. A typical mineral filler completely passes a 0.060 mm (No. 30) sieve, with at least 65 percent of the particles passing the 0.075 mm sieve. Dry-ground calcium carbonates are among the least expensive white fillers available. Wet-ground products are produced in finer particle size ranges. Wet-ground fine and ultrafine products are also sold in 75% solids slurry form for highvolume paint and paper applications.Calcium carbonate is also the most widely used filler in adhesives and sealants.
