Asphalt The largest use of asphalt/bitumen is for making asphalt concrete for road surfaces and accounts for approximately 85% of the asphalt consumed in the United States. Asphalt concrete pavement mixes are typically composed of 5% asphalt/bitumen cement and 95% aggregates (stone, sand, and gravel).he asphalt/bitumen in the removed material can be reactivated and put back to use in new pavement mixes. With some 95% of paved roads being constructed of or surfaced with asphalt, a substantial amount of asphalt pavement material is reclaimed each year.

Different types are distinguished according to the process used to bind the aggregate with the asphalt. Hot mix asphalt concrete (HMAC) is produced at 320°F (160°C). This high temperature serves to decrease viscosity and moisture during the manufacturing process, resulting in a very durable material.
