  • Patent number: 9222227
    Abstract: An extendable screed has independent height and angle of attack adjustment for a lower extender frame. At least one post and cylinder assembly are used to couple the lower extender frame to an upper extender frame at a pin that allows rotation of the lower extender frame relative to the upper extender frame. A vertical adjuster uses a drive rod with a pivoting attachment at the lower extender frame. An axis of rotation of the pin and an axis of rotation of the pivoting attachment are co-linear. This arrangement allows lower extender frame to move vertically while allowing angle of attack adjustments to be made about the co-linear axes of rotation. Simple screw adjusters displaced from the axis of the pin and collet assemblies allow raising and lowering the back of the lower extender frame to adjust the angle of attack.

    Abstract: A water-impermeable grout containment sheet and a method for using the sheet, for example, during the construction of a roadway to support vehicular traffic. An excavation is first cut into a road bed, and a moisture (i.e., water) impermeable grout containment sheet is laid inside the excavation. A plurality of concrete panels are positioned adjacent one another to be coupled together within the excavation, such that at least one of the panels sits on top of the water-impermeable grout containment sheet. Grout is then pumped below the one panel to hold the panel in place within the excavation. The water-impermeable grout containment sheet lies between the grout and the road bed to establish a containment envelope to stop the grout from migrating away from the panel and prevent water from seeping outwardly from the grout into the road bed and into the grout from the excavation.

    Abstract: A traffic bearing structure with a permeable pavement includes a subgrade, a base positioned on top of the subgrade, and a wear surface positioned on top of the base. The base includes aggregate compacted in a single lift, where the aggregate in the base includes different sized particles mixed together. The wear surface includes a permeable pavement. The particle size distribution of the aggregate in the base is selected to provide adequate stability and permeability for the permeable pavement.

  • Publication number: 20110142540
    Abstract: The present invention relates to a method for applying a crack resistant coating on a surface, where the crack resistant coating increases resistance to high vertical and horizontal movements and high shear stresses on the surface. The method comprises the steps of applying a binding material to the surface, applying an aggregate mixture within 15 seconds of applying the binding material to the surface, and allowing the binding material to fill some of the air voids in the aggregate mixture to form a substantially voidless layer with a height of at least 0.38 cm.

  • Patent number: 7918624
    Abstract: A method for bonding together an existing substrate layer and a pavement layer, such that a strong adhesive bond is formed by using a tack coat, provided by an asphalt emulsion, in between the layers as the bond coat. The tack coat layer is a low-tracking coating which cures quickly such that the pavement layer may be applied to the substrate, hours to days after the emulsion is applied to the substrate. The asphalt emulsion comprises at least a first phase of from about 30% to about 70% of an asphalt composition, about 30% to about 70% water, and about 0.1% to about 3.0% emulsifying agent, stabilizer and/or additives, or 0.1% to about 30% if polymeric or other additives are also included.

  • Publication number: 20110064517
    Abstract: A pavement such as a road, driveway, sidewalk, parking lot or the like, formed with pervious concrete material and one or more basalt reinforcing members embedded in or positioned below the pervious concrete material. The one or more basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable or supporting loads as normally experienced on pavements. The one or more basalt reinforcing members may be basalt rebar rods, or basalt rebar rods having a Figure-Eight shape, or a mesh made of basalt strands. In one example, the pavement may also include a layer of filtration fabric positioned below the basalt reinforcing members. Various methods are described for forming pavements, roads, driveways, sidewalks, parking lots or the like. Such a pavement allows water or moisture to pass through the surface of the pavement and be filtered. Such a pavement reduces flooding and the need for complex storm drainage systems adjacent to the pavement.

    Abstract: A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.

  • Patent number: 7802941
    Abstract: The present invention is directed to a rut resistant coating and a method for applying the rut resistant coating on an existing surface for increasing resistance to high vertical and horizontal strains and high shear stresses. The method includes applying a binding material layer of the rut resistant coating on the existing surface to provide a substantially impermeable moisture barrier to the existing surface, the binding material layer containing less than about 11% of the total binding material of the rut resistant coating. After applying the binding material layer, an aggregate mixture layer is applied on the binding material layer to provide the wear surface of the rut resistant coating and support and structure to the rut resistant coating to resist rutting, the aggregate mixture layer containing an asphalt solution.

  • Patent number: 7798744
    Abstract: This invention relates to a novel seal coat process and equipment for applying the seal coat to improve the reliability of seal coat aggregate retention to the surface of the pavement by increasing the surface area of aggregate covered with binder and interlocking the aggregate with finer gradation material such as choke stone. It also relates to the use of lower amounts of asphalt binder, lower amounts of aggregate application, lower quality of aggregates, use of softer binders, and faster release to traffic times.

  • Patent number: 7740414
    Abstract: In one aspect of the invention, an apparatus for directional degradation of a surface comprises an attachment assembly connected to a motorized vehicle comprising at least one degradation tool. The at least one degradation tool comprises a substantially cylindrical rotary degradation element having a substantially cylindrical working surface formed about a rotational axis. A plurality of cutting inserts is embedded within the substantially cylindrical working surface and is adapted to degrade a surface in a direction substantially normal to the rotational axis. At least one of the plurality of cutting inserts comprises a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The superhard material comprises a substantially pointed geometry with an apex comprising a 0.050 to 0.160 inch radius and a 0.100 to 0.500 inch thickness from the apex to the non-planar interface.
