Stage III: Hot Bins Calibration. Hot bin calibration should be done for each type of asphalt according to the aggregate percent passing in asphalt mix design which is approved from the M.P.W to determine specified weight scales to be taken from each different fraction.

What is an asphalt batching plant?

Hot-Bin Sampling Most modern hot-mix asphalt plants are equipped with devices for sampling hot aggregate from the bins. These devices vary in design but usually serve to divert the flow of aggregate from the feeders, or gates , under the bins into sample containers.
