Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

The amount of bitumen, required to produce a given percentage of voids in the mix is largely a function of the surface area per unit weight of aggregate, which is a function of the particle size. This is the reason that the optimum bitumen content is larger for mixes with a small-top size aggregate than for a large top-size aggregate.
