Difference Between Asphalt & Bitumen | Bitumen vs Asphalt ...

Asphalt is produced in a plant that heats, dries and mixes aggregate, bitumen and sand into a composite mix. It is then applied through a paving machine on site as a solid material at a nominated or required thickness, relative to the end use. Asphalt results in a smoother and more durable asphalt road surface than a bitumen-sealed road.
