Abstract: A road construction apparatus having a spreader, a pivotable trimmer assembly and an auger assembly. The trimmer assembly is movable between a first operational position and a second storage position. The trimmer assembly includes a housing, a rotatable cutter and a drive mechanism for rotating the cutter. A power drive system is coupled to the drive mechanism for rotating the cutter and moving the trimmer assembly between the first and second positions. The apparatus includes drive means for moving the apparatus on a supporting surface. A power source is coupled to the drive means and power drive system.

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.
