  • Patent number: 4917537
    Abstract: The multiple panel lining system is positioned adjacent to and supported by an inclined support surface. A horizontally extending support cable is positioned adjacent to the inclined support surface. Each of a plurality of spaced apart anchors is secured to the inclined support surface and to the support cable to maintain the support cable at a fixed vertical elevation and to transfer loads imposed on the support cable to the inclined support surface. A series of foldable panels with an open mesh network are draped over and supported from above by the support cable. Each panel includes an inner layer which contacts the inclined surface and an outer layer which is placed above and overlaps the inner layer. A first sealant layer is applied to and supported by the mesh network of the inner layer of the panel. A second sealant layer is applied to and supported by the mesh network of the outer layer of the panel and by the first sealant layer.

  • Patent number: 4448352
    Abstract: A manually manipulatable spray mechanism for connection to a supply apparatus having a source of molten asphalt under pressure for applying a sprayed coating of molten asphalt on selected areas of a paved surface. The spray mechanism is configured so that its asphalt spray pattern may be adjusted to suit the job being accomplished, and, to provide for recirculatingly returning the molten asphalt to the supply apparatus when the spray mechanism is in the inoperative or stand by state.

  • Patent number: 4390304
    Abstract: A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.

  • Patent number: 4279056
    Abstract: A machine for cleaning residual and foreign materials from random cracks and expansion joints in pavement subsequent to the opening of such cracks and joints and preparatory to placement of filler-sealer materials therein. The machine includes an open wheeled carriage which carries a platform between its side rails and an engine is mounted on the platform to drive a rotary brush and to drive a blower mechanism. The engine platform is pivotably connected to the carriage for raising and lowering the rotary brush, and the outlet from the blower mechanism is fixed to the wheeled carriage immediately behind the rotary brush.

  • Patent number: 4204714
    Abstract: A machine for opening the joints and random cracks in pavement preparatory to placement of a filler-sealer material therein. The machine includes an open carriage having an opposed pair of side wheels and a shroud mounted in the carriage intermediate the side wheels. A cutter wheel is journaled in the shroud for rotation about a horizontal axis, and the cutter wheel is driven by an engine mounted atop the shroud. The shroud is pivotably coupled to the carriage for raising and lowering of the cutter wheel by moving the axis of the cutter wheel in an arc which passes through the axis of the carriage wheels.

  • Patent number: 4171849
    Abstract: An apparatus for removing sealants from expansion joints in pavement slabs preparatory to replacement of the sealant is adapted for demountable attachment to the rear of a motorized vehicle. The apparatus includes a frame which is pivotably movable about a horizontal axis by means of a linear actuator. A carriage, having a cutting tool bit carried in a tool holder at the trailing edge thereof, is supported on the frame so as to be pivotably movable therewith with such movement employed for positioning and holding the cutting tool in the joint being cleaned. The carriage is free to laterally slide relative to the frame for freely tracking the expansion joint being cleaned.
