Hot-mix asphalts made using a batch process mix aggregate (e.g., gravel) with asphalt cement in a pugmill. Heat is applied to each component before mixing to remove moisture from the aggregate and to make the asphalt more fluid. Drum-mixing processes heat and blend the aggregate with asphalt at the same time in a drum mixer.

Asphalt is produced in an asphalt plant. This can be a fixed plant or even in a mobile mixing plant. It is possible to produce in an asphalt plant up to 800 tons per hour. The average production temperature of hot mix asphalt is between 150 and 180°C, but nowadays new techniques are available to produce asphalt at lower temperatures. (See below).

Cold-mix asphalt is made of quarter inch chip and proprietary oil. This specific make-up keeps the asphalt soft and helps it repel water. As its name suggests, cold-mix asphalt does not need to be warm to be used in asphalt repair. Additives in the oil keep the mixture soft all year long to allow for pothole patching in different types of weather.

Asphalt is a sustainable paving solution made from a mixture of aggregates, binder, and filler. Aggregates are processed mineral materials such as crushed rock, sand, gravel, slags, or various recycled materials. Binder is used to unite the aggregates together to form a cohesive mixture. Bitumen is most often used as the binder.

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.
