Why Use Asphalt Instead of Concrete?

Like concrete, asphalt is made using aggregate. Its binder, however, is bitumen, a dark, sticky substance derived from crude oil. When roads, parking lots or driveways are built using asphalt construction, hot asphalt (bitumen mixed with fine aggregate) is poured onto a bed of heavier aggregate and then pressed into it with a steamroller.
