Abstract
A grader for a roadway surface includes a material hopper having a hopper inlet, and a hopper outlet. The hopper outlet is configured to flow material from the hopper onto the roadway surface. A grader blade is located rearward of the hopper outlet relative to a travel direction of the grader along the roadway surface. The grader blade has a lowermost blade surface such that a blade height from the lowermost blade surface to the roadway surface is selectable changeable to provide a selected thickness and/or distribution of the material on the roadway surface.
