Abstract
A method and apparatus for planing a paved roadway wherein a main frame is drivingly supported by track assemblies and a planer assembly is disposed in cutting engagement with a top portion of the paved roadway to produce a new roadway surface. An elevation positioning assembly is provided for raising and lowering the main frame in response to an external control reference such as a string line, and a cross slope positioning assembly is provided for raising and lowering one side of the main frame relative to the other side thereof for maintaining a selected cross slope. The planer assembly comprises a planing cutter that is partially surrounded by a hood that forms a material directing compartment, and spray nozzles produce a vapor mist within the compartment. A floating moldboard is yieldingly forced into contact with the roadway to the rear of the planer assembly and cooperates with a reclaimer assembly to receive and transport the removed pavement material to a selected depository. In one embodiment, a road sweeper is pulled behind the main frame to remove any loose material that may remain on the new roadway surface.
