Maintain the approved Quality Control Plan in effect for the plant to which it is assigned until the Engineer rejects it in writing. Include in the plan the sampling, testing, inspection and the anticipated frequencies of each to maintain process control. A recommended series of sampling, testing and inspecting activities are shown in Table 331-4.

Asphalt batch plant is a widespread type of asphalt mixing plant that produces asphalt in batches. That is, all the individual materials are weighed and metered separately, and every 45-60 seconds a complete batch is produced.

all elements of the plant ideally coordinated – from process analysis and design of the system components through to controls for all components of the plant. Well over 3 300 asphalt mixing plants are in op-eration every day under tough conditions – a figure that speaks for itself. brands Agencies and sales partners

Industry Overview: Asphalt plants make paving material by mixing various sizes of stone (often termed aggregate) with a viscous binder. Different grades of material are produced, using and/or recycled feed material, primarily by using different aggregate size gradations. The organic binder used in the process varies seasonally.

As the process of each type changes, the quality of the end product also differs. Continuous asphalt plant process flow. The starting point of the asphalt drum mix plant process is the continuous feeding of cold aggregates into the feeder bins. Aggregates have to be fed as per the size into different feeder bins.
