ATT-17/96, PLANT CALIBRATION Part I, Drum Mix …

Dry Mix Prod. If using a split stockpile and/or if adding blend sand, filler or coarse material to the crushed aggregate, the cold feed bins of the drum mix plant must be calibrated. The bin calibration is performed after the calibration of the belt scale and test weights. Drum plants have from 2 to 4 cold feed bins.


BATCH PLANTS Batch plants obtain their name because during operation the asphalt mixture is produced in batches. The size of batch varies according to the capacity of the plant pugmill (the mixing chamber where aggregate and binder are blended together). A typical batch is approximately 6000 lb.

The purpose of the plant calibration is to ensure that the plant accurately proportions the asphalt and aggregate. The belt scale, test weights and cold feed bins are part of the aggregate system and require calibration. Aggregate is diverted to a truck, the aggregate is weighed and its weight is compared to the totalizer tonnes counted.


10.6 Record the asphalt temperature at the time of metering. An accurate reading is essential to test accuracy. 10.7 Using the plant control panel, cause one batch quantity of asphalt to be metered into the container. CAUTION: Take care that the metered asphalt does not cause the container to overturn.
