Make sure that the weigh box containing the total batch does not come in contact with anything that prevents a true indication of the batch weight. When intermediate storage, such as a silo, is used for HMA, periodically check the batching by comparing the total weight of the batches in a truckload with the platform scale weight for the same load.
