  • Publication number: 20140308076
    Abstract: Disclosed may be an intermediate surface for supporting a small paver, wherein the surface can also be used to exchange heat with the pavers. In one embodiment, the apparatus may be a hextray defined by a frame with a hexagonal lattice for supporting pavers. The hextray preferably features a tubing track throughout the lattice to accommodate heat exchange tubing. In operation the hextray may be positioned above a pedestal or directly on a subsurface. In embodiment, the hex tray may be outfitted with insulation and a metal plate so that heat may be exchanged with pedestals via fluid passing through tubing installed throughout the hexagonal lattice. In a preferred embodiment, the hextray features a slot in its corners for receiving a locking disk or locking slider.

  • Patent number: 8747021
    Abstract: A transport apparatus for the engagement, orientation and installation of a unit of paving blocks is comprised of a support frame having a pair of spaced-apart aligned pivot connections. Support arms are pivotally connected to each pivot connection under the support frame. Two or more spaced-apart parallel block engaging arms are displaceably secured by connecting posts to the pair or parallel support arms. A piston simultaneously displaces the parallel support arms and the block engaging arms. The block engaging arms each have two or more suction cups for releasable securement to a top face of respective ones of paving blocks in the unit of paving blocks. When the piston rod of the piston is at a first position all of the suction cups are aligned on transverse parallel axis and when at a predetermined second position they are disposed in alignment on parallel angulated axis. The method of installation is also described.

  • Patent number: 6752568
    Abstract: A device for placing individual road markers in desired configurations along a road surface comprises an application wheel having at least one aperture connected to a frame by an axle. The frame and application wheel are then connected to a trailer that is pulled along behind a pulling device. The apertures of the application wheel are dimensioned to receive a part of the road marker in a position tangential to the surface of the application wheel. As the application wheel rolls over the surface, the base portion of the marker contacts the road surface. An adhesive portion of the marker causes the base of the marker to become adhered to the road surface. As the application wheel continues to roll, the standing reflective portion of the marker is withdrawn from its position within aperture of the application wheel, and remains in a desired location upon the road surface.

  • Patent number: 4479739
    Abstract: A road construction machine for paving road surfaces with road stones or the like is disclosed which moves over the paved surface which has already been laid, without the use of guide rails. The machine carries a supply of road stones supported on a lift table. Each uppermost road stone slab is removed from the supply stack and inserted into a semi-circularly shaped transfer chute positioned at the forward end of the paving machine. The road stones are conducted through the chute and deposited onto the subgrade surface so as to be pressed sequentially against a previously laid pavement stone. As the road construction machine moves forwardly along the paved surface in the direction of the paving operation, hydraulic ram means serve to firmly press and flatten the laid stones into paving condition on the subgrade surface, utilizing the weight of the slab stack carried in the machine.
