What is Asphalt Concrete? (with pictures)

Asphalt concrete, commonly called asphalt, tarmac, pavement or black top, is a composite material used in the construction of roadways and parking lots.This composite is a mixture of a petroleum byproduct, asphaltic bitumen and aggregate materials. In asphalt concrete, the asphaltic bitumen acts as a sort of glue that binds the aggregate pieces together.

Continuous Asphalt Mixing Plant-Reliable Quality High ...

The use of asphalt mixing plant can save more time to make the asphalt. Making asphalt by traditional equipment needs to go through complex process, costs more manpower and material resources. The asphalt quality also has a lot of problems. Asphalt mixing plant not only can avoid unnecessary operation process, but also can save more raw materials.

Hot Mix Asphalt Plants

around 6:30 a.m. and produces hot mix asphalt until 2:00 p.m. A simplified process flow schematic is shown in Figure 2-1. Under normal operations a truck pulls into the load-out bay and is loaded with 20 to 32 tons of asphalt concrete in 5 to 10 minutes. The exact mix of each batch (aggregate size, etc.) is determined by the customer’s request.
