The Real-Time Quality Control System for Asphalt Plants utilizes Automatic Belt Sampler (ABS) which sweeps a representative sample off a moving conveyor belt and deposits it into a Drying Oven. The drying oven receives the sample, weighs the sample, dries the sample, and reweighs the sample. A test report is produced which shows the moisture content of the sample. The dried sample is then deposited into the Field Gradation Unit which performs a complete sieve analysis of the sample. All test data is displayed on an Excel spread sheet and sent to the Asphalt Plant Control House.
Documents and Test Methods will be added as they become available.
