  • 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.
