Concrete Batching: NRMCA, Scale Company, and Calibration

Dec 28, 2017 · Aggregate scale capacities will generally govern the minimum amount of test weights required – about 4000 lbs is typically needed. (There may be situations where the plant configuration does not permit the minimum test weights to be used and that has to be verified by the plant inspector).

Method for Testing of Material Production Plants

The asphalt ignition test (AASHTO T308) is almost always used to measure asphalt content of plant produced mix. This test requires a calibration to correct for the aggregate weight loss during the test. This calibration can be performed during the plant production to ensure that the lab is set up to accurately measure the asphalt content as soon as full scale production begins.
