ABSTRACT:
The improvement to machines for filling trenches in paved surfaces has two hoppers hydraulically operated to deposit selected course material directly into the trench from a substantially vertical drop in substantially equal quantities from each side. At least one of the hoppers moves responsive to the movement of guide rails that follow the contours of the trench. A vertically adjustable strike-off plate, adapted to define a course level above or below the level of the surrounding paved surface, has two components, at least one of which moves relative the other responsive to the guide rails to accommodate trench width, and includes apparatus for laying down a window of paving material during a final pass and pushing it into a mini-trench created by intrusion of the guide rails.
