Asphalt Definitions and Terms
A batch plant is a manufacturing facility for producing asphalt paving mixtures. A batch plant distributes the aggregate constituents proportionately into the mix by weighed batches and adds asphalt binder by weight. The aggregates are first fractionated through a screening deck into hot bins and then proportioned into a weigh hopper. The batch of aggregates is emptied into a pugmill, where the asphalt binder is weighed in and mixed to form the completed asphalt mixture.
