ABSTRACT:
A road scraper includes a frame having forwardly positioned blades extending rearwardly and laterally for directing loose material against a rear blade extending angularly in the opposite direction between rearwardly extending side frame members thereby causing loose material on the road to be redistributed across the road under the rear blade on the back side of the frame. A rearwardly positioned dam blade cooperates with the rear angular blade to cause loose material to be accumulated and then discharged through a passageway between the rear end of the dam blade and the angular blade.
