ABSTRACT:
Asphalt cutting apparatus for breaking up and windrowing old asphaltic pavement on a roadway or the like including the pavement adjacent to a curb or gutter. A plurality of laterally spaced, sharpened cutter discs are freely rotatably mounted on a support carriage. The support carriage is attached to a frame pivotally coupled at a forward pivot to a prime mover such as a truck or similar vehicle for movement along the asphalt surface. As the cutter discs are moved along the asphalt surface a hydraulic clamp cylinder provides a vertical movement about the forward pivot to vary the depth of cut and also maintains a downward pressure on the cutter discs and forces the discs to roll through and cut up the asphalt. The construction and mounting of the support carriage is such that the discs are adjustably movable laterally axially along a horizontal axis for selective positioning adjacent to a curb or gutter and are further adjustably movable about a pivot to slope laterally outwardly and downwardly so that the discs are positioned at different cutting depths relative to one another for cutting an asphalt surface that is sloped for drainage purposes.
