A roof paver system includes a plurality of roof paver elements having alternating dovetail-shaped and tapered grooves and an upper surface having raised portions to generate vortices for preventing wind from lifting the elements and to provide a safety tread. Connector members are provided in some of the dovetail grooves to interconnect the roof paver elements to further prevent their displacement. The tapered grooves break the vacuum between the roof paver elements and the molds in which they ...

A paver block edging system is described for positioning a row of edge blocks over a support surface. The edging system includes an elongated channel including a floor formed to receive and support a paver block. A connector is provided on the channel to be releasably received over a bendable member that is not part of the system. The connector releasably secures the channel to the bendable member and angularly orients the channel relative to the bendable member. The bendable member may thus be ...

Two feed conveyors and two spreader augers are independently driven, each by its own drive motor. The control means for each feed conveyor includes a sensor at the discharge end of the feed conveyor and means responsive to changes in the level of the paving material at the sensor for proportionally increasing the drive speed of the conveyor as the level drops and proportionally decreasing the drive speed of the conveyor as the level rises. The control means for each auger includes a sensor adjac...

The invention relates to a vibratory paving screed for a paver, comprising a baseplate and a vibration drive therefor and also comprising a front wall which is mounted upstream of the baseplate in the paving direction, is fixed with respect to the baseplate and engages with the baseplate, in which arrangement the baseplate comprises a section of uniform thickness and, in the region of its front edge, a separate, solid strip which is connected to the section and has a metering slope and a flat ru...

Interlocking paver system for the use of constructing sidewalks, pathways and decks being formed from a light weight material for easy handling. Joined together by a plastic spline with gripping teeth, which when placed in spline receiver slots on sides of paver, which has a protruding upper edge that surrounds the entire perimeter allowing the pavers to tilt up or down, which allows the pavers to be placed on uneven or unlevel surfaces and prevents pavers from separating and from moving side to...

A paver (1) with a chassis (2) at the front in the paving direction, with a hopper (11) for receiving material to be paved and, at the rear, with a floating screed (5), two centrally arranged longitudinal conveyor devices (9,10) guided through a shaft (8) being provided between the hopper (11) and a distributor auger (7) located in front of the screed (5) in the paving direction, the hopper (11) being open relative to the longitudinal conveyor devices (9,10) and an additional conveyor device (33...

A paver with a collecting hopper for collecting aggregate dumped into the paver. Rotating discs with discontinuous expanses caused by voids in the discs on rotation of the discs mix aggregate and move the aggregate to a region where the aggregate dumps in advance of a screed in the paver.

A slip-form paver is provided in the form of a tractor (2) including a machine frame (4) having substantially parallel longitudinal beams (8) at opposite ends of which are track assemblies (14). The machine frame (4) includes a base frame (20) and telescopic cross beams (18) located between the base frame (20) and the longitudinal beams (8). An intermediate frame (24) is located beneath the base frame (20) and is selectively vertically adjustable. Two working mechanisms (28, 32) are in transvers...

In a slip-form paver comprising a machine frame (4) including longitudinal beams (8) extending in parallel to the working direction, and transverse beams (18,20), and comprising a chassis (2) including a plurality of truck assemblies (14,15) adjustable in height by means of a lifting column (10) and carrying steerable tracks (16) maintaining the plane of the machine frame (4) in a predetermined position, it is provided that a slidable traverse member (22) is mounted to at least one transverse be...

An asphalt paver has a suspension which, in normal use, applies much of the paver weight to the screed, but includes a provision for forwardly tilting on bogie assemblies, to raise the screed and spreading auger for highway travel. Main suspension frames are mounted beneath the hopper on trunnions and extend rearwardly to mount wheels aft of the center of gravity of the paver but forward of its lateral spreading auger. When jacks are operated downward to bear on the rear portions of the bogie su...
