An asphalt spreader for spreading asphalt into ruts in a roadway. The spreader includes a main blade that has wings on either end to keep asphalt before the blade. The blade also has a wedge-shaped center portion which diverts asphalt toward either side of the blade to direct more asphalt into the ruts. The vertical clearance of the wedge-shaped center portion can be separately adjusted so as to control the amount of asphalt that is laid down in the center portion between the ruts. In addition, the bottom surface of the blade is inclined rearwardly with respect to the blade to form an acute angle with the groundplane.
