Batching Plant For Asphalt - Manufacturing Plant, Detailed

Batch Asphalt Plants literally make Hot Mix Asphalt (HMA) one batch at a time. They have the advantage of being able to taylor each truckload of HMA to exact specifications, whereas a drum asphalt plant generally produces high volumes of the same recipe. Aggregate, RAP and asphalt cement are mixed in a pug mill mixer rather than a drum.
