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 concreteAug 11 2018 Fine Aggregates are usually sand or crushed stone that are less than 9 55mm in diameter When the aggregate is sieved through 4 75mm sieve the aggregate passed through it Natural sand is generally used as fine aggregate silt stone dust and clay also come under this category
