Abstract

See full text

A system for controlling a vibratory effort on an asphalt mat includes a screed having a screed frame, a screed plate, and a vibratory mechanism. The screed plate and the vibratory mechanism are mounted on the screed frame and the vibratory mechanism is configured to vibrate the screed frame. The system further includes a sensor mounted on the screed frame, and configured to generate signals indicative of a vibrating parameter of the screed frame. The system further includes a controller in communication with the sensor and the vibratory mechanism. The controller is configured to receive the vibrating parameter, and further compare the vibrating parameter to a threshold parameter. The threshold parameter is the decoupling point of the screed frame. The controller is further configured to control the vibratory mechanism to reduce the vibrating parameter when the vibrating parameter exceeds the threshold parameter.
