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.
