Abstract
Screed plate assemblies, screed units, and pavers and methods for operating such assemblies, units, and pavers are disclosed. Example assemblies, units, and pavers include a screed plate assembly described herein. Such a screed plate assembly includes a screed plate, sensor(s) and actuator(s). Each sensor is mechanically coupled to the screed plate, and operative to sense a pressure on the screed plate and to communicate the sensed pressure. Each actuator is mechanically coupled to the screed plate, and operative to receive an input related to controlling an angle of attack (AoA) of the screed plate and to control the AoA of the screed plate based on the received input independent of controlling an AOA of another screed plate.
