Aggregate is usually described as either coarse aggregate (retained 4.75 mm) or fine aggregate (passing 4.75 mm). Aggregates generally make up about 95 percent of the total mass of hot-mix asphalt mixtures and 80 percent by mass of concrete - aggregate properties are, therefore, critical for quality hot-mix asphalt or concrete.
