An access mat comprises a single unitary body having a generally planar upper wall, a bottom wall and side walls joining side edges of the upper wall and the bottom wall, formed by pultrusion from composite material comprising longitudinally continuous fibers and a set resin so as to define an elongated tubular body enclosing a hollow interior. The unitary body includes integrally formed parallel reinforcing ribs bridging the hollow interior in a thickness direction. The bottom wall has recessed channels therein receiving pultruded elongate connector members each shaped to fit into a respective one of the recessed channels with a bottom surface of the connector member coplanar with the bottom surface and a top surface of the connector member in engagement with a raised surface of the respective recessed channel for connecting of an end of the body to an adjacent end of another body by bridging between the bodies.

A structural system is provided that includes at least two pavers partially defining a paved surface, the pavers partially defining a void between them. The system also includes a permeable joint located in the void between the pavers, where the permeable joint also partially defines the paved surface. The permeable joint includes a base layer formed of aggregate and bonded together with a non-cement binder, and a membrane layer formed of aggregate that is sized smaller than the aggregate of the base layer, where the aggregate of the membrane is also bonded together with a non-cement binder. The membrane is less permeable than the base layer and is located above the base layer.

The present disclosure provides a method for manufacturing of paver block and bricks. The method includes addition of cementitious materials. In addition, the method includes addition of conventional aggregates. Further, the method includes addition of additives. Furthermore, the method includes addition of binding materials. Moreover, the method includes homogenization of the added materials to obtain a first mixture. Also, the method includes addition of a hardener solution to the first mixture. Also, the method includes mixing the first mixture with the hardener solution for 5 minute to 30 minute to obtain a second mixture. Also, the method includes casting the second mixture into a mould to obtain a solidified part. Also, the method includes curing the solidified part in atmospheric air.

A system for supporting a paver layer that includes a layer of sand, a concrete layer, a base, drain pipes, and a gravel layer. The layer of sand, the concrete layer and the concrete layer are each formed in a substantially horizontal direction, with the layer of sand being formed above the concrete layer and the concrete layer being formed above the base. The drain pipes are provided in a substantially vertical orientation, with an upper end of each drain pipe provided within or slightly below the concrete layer.

One inch paver tiles may now be set over a concrete pad for use by vehicular traffic. The method and dry concrete mix may be used to overlay concrete driveways. The paver tiles may be laid over a dry concrete mix comprising a latex polymer, Portland cement, sand and a hydration control agent. After laying the paver tiles in a field over the concrete mix in the dry state, a border of paver tiles or other material may be laid in a wet concrete mix prior to hydrating the field paver tiles. The dry concrete mix cures after hydration to form a strong layer adhering the paver tiles to the concrete pad for use by vehicular traffic.

A module for use in constructing a pathway for traffic comprises a base member that defines a lateral groove disposed at its perimeter edge and extending along a first end, and a tongue structure disposed at its perimeter edge and extending along a second end. The tongue structure is received in the lateral groove and comprises a plurality of tongue portions that includes a first type of tongue portion and a second type of tongue portion disposed in alternating relation along the length of the tongue structure, to thereby define a throughpassage for receiving a securing rod. The first and second tongue portions have no vertical overlap one with the other. To form a pathway for traffic, the modules are placed in perimeter-edge to perimeter-edge relation, with the tongue structure of the modules inserted into the lateral groove of an adjacent module, and are secured together by the securing rod.

Modular floor tiles include a first surface configured to receive weight. The first surface is supported by primary walls interior to and extending the full height of the tiles, and which may be intersecting to form a grid. Secondary walls of a lesser height support the primary walls, may be non-linear such as circular, and may support either side of vertices of intersecting primary walls. Joining members and corresponding receivers in the sides of tiles are dimensioned to engage one another from adjacent tiles to join the tiles and restrict lateral movement. Fastener(s) in each tile are associated with slots and may be selectively moved between unlocked and locked positions to restrict vertical movement. Some embodiments include cable channels with corresponding cover plates, and inclined portions providing ramps. Any number and combination of tiles may be connected to one another to form a modular flooring system.

Methods, systems and devices for detectable warnings are disclosed.

The present invention is directed to a paver edge restraint system for reducing shifting of a paver units making up a paved surface having one or more edge restraints installed along at least a portion of the periphery of the paved surface. The paver edge restraint system includes at least one peripheral edging member, at least one edging securement member for holding the at least one peripheral edging member to the ground, at least one paver retention strap that extends underneath a plurality of paver units constituting a portion of the paved surface, and at least one clamping unit mounted on the at least one peripheral edging member for securing and tightening the at least one strap to maintain the joint integrity of the plurality of paver units installed above and adjacent to the at least one strap.
