Abstract
A method and apparatus is disclosed for controlling material feed for asphalt pavers. The material feed system includes a screed, feeder conveyor and a spreader auger. A sensor measures a material volume and transmits this information to an electronic control module (ECM). This information may be used as the target material volume, which the ECM may use to calculate a corresponding conveyor speed and auger speed. The sensor monitors the material volume as paving commences, and the ECM maintains the initial calibrated target size by adjusting the auger and conveyor rotational speeds.
