A modular system of rectangular pavers which can be laid down across a grass area to support foot or vehicle traffic while permitting grass to grow through apertures in the pavers. Each paver is made up of a base plate having a rectangular grid of upstanding walls secured thereto. An aperture is provided through the base plate within each grid cell. The maximum distance between opposite walls in each cell is about one inch. Typically, the pavers will have thicknesses of up to about one inch. The...

A paver for spreading aggregate over a surface. The paver includes a collecting hopper for receiving material from a dump truck. Rotating discs form a portion of the floor of the collecting hopper, and on operation of the discs aggregate is moved to cascade from a rear edge of the collecting hopper into a feed hopper. Material flows from the feed hopper to a region in advance of a screed in the paver. The collecting hopper is tiltable fully to clean aggregate therefrom.

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 vortexes for preventing wind from lifting the elements and to provide a safety tread. Connecting members are provided in some of the dovetail grooves to interconnect the roof paver elements and further prevent their displacement. The tapered grooves break the vacuum between the roof paver elements and the molds in which the...

A vinyl walkway paver, particularly the one used as a paving stone with grass contained therein. The paver can be integrally formed to have a surface with a plurality of ridged bodies which are different in sizes. The center of the paver is a recessed portion, the four sides of the recessed portion form a hollow frame, the corners joining the diagonals of the frame are provided with corner holes and corner blocks. By such configuration, a plurality of pavers can be laid on the walkway, the centr...

A paver system is made up of a plurality of pavers. The pavers are adhered onto a grid, and a handle is attached to the grid to enable the system to be carried by an installer. The grid onto which the pavers are adhered may be flexible. There may be a plurality of handles, and the handles may be connected by a band fastener. A paver installation may have a prearranged pattern using multiple paving systems.

The invention relates to a paving screed for a paver, with a basic screed and with at least one lateral extendable screed part which is connected to the basic screed via hydraulically actuable tensioners. The height of the extendable screed part can be adjusted via a height setting device which comprises vertical spindles which are coupled to the extendable screed part and are held on the basic screed rotatably relative to the latter. The spindles are adjustable via a common drive motor, it bein...

A paver machine for applying paving material to narrow paths is disclosed. The machine includes a storage hopper and frame elevated above a roadbed by at least three wheeled unit members. A free-floating screed assembly located beneath the hopper and pivotally attached to the frame applies a paving material matte to the roadbed as the paver machine is moved along by a front end loader or the like.

The concrete path paver of the invention comprises a generally rectangular open-ended box having a front wall and an inwardly sloped rear wall rigidly connected between a pair of side walls to define a bottom opening. An adjustable screed is positioned underneath the sloped rear wall from the rearward side of the bottom opening and extends a significant distance beyond the lower edge of the rear wall to form a slip-form mold. A platform is affixed rearwardly of the rear wall above the screed all...

A screed for an asphalt paver in which the bottom plate thereof is made of steel in the Brinell hardness range of 450-500 to engage road surfacing material. Stainless steel threaded studs are welded to the upper surface of the bottom plate for attachment of the screed to the asphalt paver.

A controller for controlling the slope of a screed supported by support arms wherein the screed is moved over a distance includes a first slope sensor which develops a first sensor signal representing the slope of the screed, a second slope sensor which develops a second sensor signal representing the slope of the support arms and a first summer which sums the first sensor signal and command signal indicative of a particular screed slope to develop a first error signal. An integrator integrates ...
