An granite asphalt plant is a machine designed to produce hot-mixed asphalt (HMA). There are two types of plants: batch and drum. They both produce the same essential mix, but through different processes.

An granite asphalt concrete plant can be set up on a construction site that needs a steady flow of HMA. This is necessary because the pliability of asphalt is based on its temperature. Transportation can cause the HMA to cool, making it no longer useful. However, it can be quite expensive to maintain an granite asphalt plant on-site. So, if only a small amount of asphalt is needed, it is best to transport it from an off-site facility.
