Bitumen is actually the liquid binder that holds asphalt together. The term bitumen is often mistakenly used to describe asphalt.

A bitumen-sealed road has a layer of bitumen sprayed and then covered with an aggregate. This is then repeated to give a two-coat seal.

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 surface than a bitumen-sealed road.

Asphalt is generally more cost effective than other paving surfaces for areas measuring 150 square metres or more. In some ways asphalt is more durable as it is resistant to ants and weeds. Bricks, slabs and pavers are prone to shifting move at corners and bends, leaving gaps in the surface which allow water and weed ingress. Asphalt has a darker colour and creates less glare than lighter concrete and limestone surfaces.
