ABSTRACT:
Apparatus and method is described for depositing salt-based materials upon highway pavements at practical speeds in a manner significantly reducing scatter. This is achieved through the expression of the materials from an impeller at a lower level of the vehicle at a material velocity commensurate with the speed of the vehicle itself. Projection of the material is in a direction or vector directly opposite that of the forward direction of the vehicle. Implementation of the method is provided with a rotating impeller having sidewalls defined by an endless belt which partially surrounds it. That portion of the impeller which is not surrounded by the endless belt forms an outlet opening from which the material is propelled. Introduction of the material to the impeller is at its center portion and is directed to those peripheral regions of the impeller which extend from a location adjacent the outlet opening and thence about a predetermined arcuate region of the rotating impeller. A plurality of rotationally rearwardly canted vanes are mounted within the impeller to aid in the acceleration and expulsion of the snow-ice control materials.
