ABSTRACT:
A particulate material spreader suitable for spreading asphalt on roadways and other paved surfaces is formed by a bucket which has a back and side walls but no bottom, and arms by which it may be carried at the rear of a vehicle and lifted or lowered by a hydraulic mechanism. Height adjusters at the sides of the bucket hold the lower edge of the back of the bucket at selected height above the roadway whereby a layer of asphalt is metered from the bottom of the bucket as the remainder of a pile of asphalt is raked away by the bucket.
