Abstract
Efficient paving operation requires that the levelling operation of asphalt be carried out accurately along a reference line which follows a given direction along a roadside. A simple and effective automatic control device for controlling the steering direction in conjunction with adjustments of the screed for an asphalt finisher (shortened to finisher) is presented. The control device automatically regulates the extension or retraction of the screeds on both sides of the finisher in reference to a visual display of the reference line following some objects along the roadside. The visual detection system of control is simple and economical and provides an accurate control over the direction of paving.
