What is asphalt batch plant?

The aggregates here can be a single sized material. The binding material also known as asphalt cement can be cutback asphalt, synthetic binders or emulsion.

What does asphalt plant produce?

The purpose of asphalt plants is to generate hot mix asphalt. These plants make use of aggregates, sand, bitumen and other such material in particular quantities to produce asphalt, which is also called blacktop or asphalt concrete.

How hot is asphalt when it comes out of the plant?

Hot mix asphalt is manufactured at temperatures between 270° F and 325° F. Depending on the environmental conditions and the distance from the hot mix plant to the project, hot mix asphalt can lose between 5° F and 25° F.

What is the degree of asphalt mix at the plant?

Conventional asphalt “hot mix” is generally produced at 150 °C or greater at the mixing plant, and subsequently compacted at around 120–140 °C. A cold mix plant using asphalt emulsion requires less initial capital investment than a conventional hot-mix plant, and is well suited for mobile use.
