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.

Abstract:

Heating apparatus is disclosed that is particularly suited for use in combination with a drum mixer for treating asphalt aggregate materials to make such materials suitable for being applied to the ground surface. The heating apparatus generally comprises a plurality of flame-emitting gas burners and a combustion chamber for producing hot gases. A refractory lined plate assembly with an array of gas distributing ports is provided for spreading out hot gases discharged from the combustion chamber over the surface area of the plate assembly and also for inhibiting the open flames from passing from the combustion chamber. The combustion chamber is constructed to withstand the impacts and high temperatures encountered during operation of the mixer, as during transport, by attaching refractory bricks with metal backing plates to a rigid framework. The plate assembly is constructed in sections that are movable relative to one another to permit expansion and contraction with temperature variations. In the combination the heating apparatus and drum mixer are mounted end-to-end in coaxial alinement and on a vehicle for vehicular movement with the plate assembly between the combustion chamber and the interior of the drum and with the heating apparatus stationary relative to the rotational movement of the drum.
