  • Patent number: 6036402
    Abstract: The present invention relates to paving and systems in respect of laying pavers, and devices to aid methods of laying pavers. The apparatus of this invention is referred to as a compensating member because it compensates for spaces between adjacent pavers as well as it compensates for any expansion of the pavers once they are in situ. The compensating member (2) is fabricated so that a portion of said compensating member is compressible and most preferably is made from at least one limb which has at least one compressible formation formed thereon or as a part thereof.

  • Patent number: 6033147
    Abstract: Top layers of asphalt surfacing are laid in hot laying method in one work cycle. A first layer of a first asphalt production type hot is placed on a surface to be covered. Simultaneously with the first layer is placed a second layer of a second asphalt production type different from the first production type hot on top of the first layer. Owing to the simultaneous laying of two different and hot on hot asphalt layers from delivered mixture from an asphalt plant, thermal potential is increased and cooling delayed, therefore a considerable improvement in properties of theses two asphalt layers is achieved.

  • Patent number: 6027280
    Abstract: The present invention provides an interlocking paving block capable of accepting an internal lamp and a pavement of interlocking illuminated paving blocks. In one embodiment, the interlocking paving block has a main body bent from 14 gauge aluminum sheet metal to form upper and lower flanges for attaching and supporting a bottom plate and a lens. The lens is made from a tough, polymeric material, such as polycarbonate sheeting. An access hole in the bottom plate allows a lamp socket and lamp to be inserted into or removed from the interior of the paver block without removing the lens. A top cap secures the lens against the main body, providing a clamping force between the lens and main body to compress a rubber gasket, thus providing an environmental seal. An interior perimeter of the top cap also provides a friction step, thereby improving traction across the top of the paver block.

  • Patent number: 6027281
    Abstract: This invention provides for painting a second coat upon a set of parallel striped lines in exact registration in one pass of a motorized painting vehicle for such applications as painting aircraft taxi stripes at airports. Beads are also registered on one of the lines in the same pass. Provisions are made for maintaining registration about curved lines by steering around curves with a shortened wheelbase vehicle and by extending paint nozzles for striping a plurality of parallel lines, typically a center twelve inch wide yellow line between two six inch wide black lines, outboard from one side of the painting vehicle. The vehicle comprises two four wheeled units articulated together by a universal articulation joint permitting vertical articulation so that the leading and trailing wheels may be lifted off the ground to reduce the wheelbase for steering around curves.

  • Patent number: 6019542
    Abstract: A D-shaped base fits tightly over a barrel to add ballast to the barrel. The base is perimeter weighted to increase resistance to tipping of the barrel. The interior circumference is designed to fit tightly on the barrel. The outer circumference includes a flat portion to resist rolling of the barrel if tipped over. As a result, if the barrel is tipped over, the base stays tightly fitted to the barrel, but if an automobile collides with the barrel, the base releases to reduce the possibility of damage to the automobile or barrel or base.

  • Patent number: 6012869
    Abstract: An expansion joint and seal for an expansion joint for use in structures where the joint has an intersection uses a seal with a solid thick keel extending along a lower edge of a central portion in an area of the intersection. The keel commences in a transition area between a conventional seal and the intersection. The seal increases in depth as the intersection is approached until it reaches a maximum depth at a mid point of the intersection. The keel minimizes distortion from racking during expansion or contraction of the joint. The seal is shaped to enable debris to be easily removed.

  • Patent number: 6009586
    Abstract: A ramp structure which may be constructed quickly to provide temporary or permanent access to all individuals between two areas of different elevation. A truss design allows long spans to form a bridge without the need for intermediate supports and related support foundations. A truss cross-connector is firmly wedged in place between two trusses and allows the quick, solid joining of two trusses without fasteners to form a strong and stable assembly to serve as ramps, bridges, elevated walkways, etc. The truss cross-connector has resistance to bending and supports the edge of a surface panel and provides a retaining pocket for the surface panel. The truss cross-connector firmly supports the trusses in an upright position when the trusses are used as railings. Surfacing panels placed between the truss cross-connectors provide a high quality, long lasting surface which is quickly installed for temporary or permanent installations, but which can be easily removed for reuse.

  • Patent number: 6007270
    Abstract: A manhole frame assembly for supporting a member that can obstruct an access opening when the level of a construction material around the opening is raised, includes an outer frame member having a support surface and a side wall extending from the support surface. The side wall is constructed and arranged with an upper surface that is substantially flush with an original level of the construction material. An inner frame member can be received on the support surface and includes a surface for supporting a member for obstructing the access opening. The side wall includes an abutment device for preventing upward movement of the inner frame member when the original level of construction material around the outer frame member is raised.

  • Patent number: 6007272
    Abstract: An improved asphalt paver having a remixing conveyor system that is adapted to substantially or entirely eliminating segregation in hot mix asphalt material delivered to the asphalt paver. The remixing conveying system includes at least one pair of parallelly spaced, oppositely pitched, counter-rotating hydraulically driven feed augers having remixing blades that intermittently displace portions of the hot mix asphalt material generally transversely to the direction that the feed augers convey the hot mix asphalt material from a hopper of the asphalt paver to spreading augers near the rear of the machine. Elongate members over the feed augers provide protection from impact forces and overloading and enhancing lateral extraction of hot mix asphalt material from the hopper. An optional feed screen provides flow control of the hot mix asphalt material in the hopper. A kit is provided for converting existing asphalt paving machines to have desegregating capability.
