Pavement Manual: Concrete Plant Operation

A batch plant is the concrete mix plant where the aggregates, cementitious materials, chemical admixtures, and water are metered and combined together to produce hydraulic cement concrete. A batch of concrete is the amount of material mixed at one time. The batch plant can be a commercial concrete batch plant or a temporary batch plant brought in and assembled by the contractor near the paving site. On large concrete paving projects, most contractors choose to mix their concrete using their own
