A method for providing a system for supporting a layer of paver blocks, the method including excavating drain holes at a depth corresponding to at least a length of a corresponding drain pipe, forming a base by pouring high porosity non-compactable material into each drain hole of the at least three drain holes, inserting a drain pipe into a corresponding drain hole, filling a hollow of the drain pipe with a non-compactable material, placing a water permeable closure across the top opening of the drain pipe, pouring a concrete layer above the drain hole, and depositing a sand layer above the concrete layer, with the sand layer covering the top opening.

A filler for a concrete structure is provided. The filler includes an organic-inorganic composite hydrogel (A). The organic-inorganic composite hydrogel (A) has a three-dimensional network structure that includes a polymer of a water-soluble organic monomer and includes a water-swellable clay mineral. The filler has a water pressure resistance of 0.2 MPa or greater. The filler for a concrete structure has excellent workability and various excellent physical properties in terms of, for example, adhesion to wet surfaces and resistance to water pressure. Accordingly, the filler is suitable for use as a filler for joints and cracks of concrete structural objects.

A paver for laying down a strip of concrete and, with a dowel bar inserter module as part of the paver, inserting dowel bars into and parallel with to the concrete strip. The dowel bar inserter module has an operational width capable of covering paved concrete strips of greater than 34 feet. In some implementations, the dowel bar inserter module has an operational width of 36 feet, 40 feet, or 50 feet.

A composition for suppressing dust particles includes from about 51% to about 100% by weight of saturated hydrocarbons, and from about 0 to about 49% by weight of unsaturated hydrocarbons. The composition has a content of wax in the range from about 5% to about 40% by weight of the total composition. A method of making and a method of using such a composition are also provided.

A walk-behind apparatus and method for cutting non-linear trenches in concrete includes a frame supported by fixed direction wheels at a front end on a fixed axis of rotation, and multi-directional wheels at a rear end to rotate on movable axes of rotation, to permit the frame to rotate about a vertical axis passing through the frame. A handle is engageable by a user walking behind the frame for pushing the apparatus forward and/or for steering. A cutting wheel has a diameter of 5-20 inches and a cutting portion having a width of 0.5-1.5 inches. The cutting rotates on an axis parallel to the fixed axis and which extends notionally through the fixed direction wheels. The cutting wheel is disposed within a protective shroud viewable by the user to permit the user to visually align and guide the cutting wheel along a non-linear path on the ground while steering.

A method of establishing a desired flow of haul trucks with respect to a jobsite can include receiving, from a paver locating device, a paver location signal indicative of a location of a paver. A central computer can establish a desired location range of the first haul truck based on the paver location signal and a first haul truck location signal.

A hot applied thermoplastic pavement composition and method of using wherein the composition comprises a modified polyamide resin in the range of between 3 and 10 percent by weight, wherein the composition contains rosin-modified esters, a copolymer, 30-70 percent by weight of a glass bead intermix, a range of between 1 and 15 percent by weight of either white or yellow pigment, the balance of the composition being selected from the group consisting of: one or more plasticizers, inorganic fillers, waxes, antioxidants and light stabilizers.

An apparatus for cutting grooves in a ground surface includes a wheeled vehicle with a tool carrier connected to the wheeled vehicle. The tool carrier is rotatable about an axis parallel to the direction of travel of the vehicle and perpendicular to the direction of travel of the vehicle. A grinding tool for cutting grooves in a ground surface is rotatably mounted to the tool carrier. The grinding tool may be movable laterally relative to the vehicle. A rotatable cam is configured so that rotation of the cam causes pivotal movement of the tool carrier relative to the forward frame. Rotation of the cam moves the grinding tool into and out of engagement with the ground surface.
