What is the difference between a batch mix and a drum mix asphalt plant?

A batch mix asphalt plant dries aggregate, then weighs and mixes each batch individually in a pugmill mixer before discharge - giving precise control over mix design and making it easy to change mix types between batches. A continuous drum mix plant instead dries and mixes aggregate and bitumen together inside a single rotating drum in a continuous process, generally favouring high sustained output over frequent mix-design changes.
