Many get confused between asphalt and bitumen. They think that asphalt and bitumen are the same, but technically they are not. Asphalt is a composite material mixture of aggregates, binder (bitumen), and sand. Aggregates used for asphalt mix could be crushed rock, sand, gravel, or slags.
Whereas Bitumen is the liquid binder that holds asphalt together. The term bitumen is often mistakenly used to describe asphalt.
