A lightweight universal panel mat made of plastic or elastomeric material and having a first section that provides a relatively flat, textured or structured top surface to facilitate movement over the mat and a second section having geometry that includes a plurality of cells having top surfaces that support the first section. The panel mats have first, second, third and fourth sides that are configured to matingly engage or connect to the second, third, fourth and first sides, respectively. The connection can be by insertion or snap-locking of one side to another, or by the use of fastening elements that more securely holds the sides together. Thus, similarly configured panel mats can be connected by interlocking to form a temporary support surface, deck, walkway or roadway. Additional side ramps and adapters can be used to facilitate installation of the mats and access to the upper surfaces of the joined mats.

A roundabout for vehicular traffic is provided from a plurality of modular blocks arranged in a generally circular roundabout pattern and affixed to a roadway or ground surface at an intersection of vehicle roadways. Roundabouts can be formed in any desired diameter. In some embodiments, the modular blocks can have a trapezoidal plan shape laid out in concentric rings. The trapezoidal shaped blocks can be cut from a length of board having a constant width and thickness. The modular blocks can be provided as a kit of parts delivered to worksite at an intersection of vehicle roadways where a roundabout is desired. Splitter islands, sidewalks, and curbing of blocks having appropriate shapes can also be provided.

An interlocking paver system including a polygon paver and a spacer paver is provided. The polygon paver may have a top level having a top level polygon paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level polygon paver perimeter contained within the top level polygon paver perimeter. The spacer paver may have a top level having a top level spacer paver perimeter and a bottom level secured to and protruding from the top level and having a bottom level spacer paver perimeter extending beyond an entirety of the top level spacer paver perimeter The spacer paver may be configured to selectively interlock with the polygon paver. The top level spacer paver perimeter, top level polygon paver perimeter, and bottom level spacer paver perimeter are different from one another.

Fall protecting flooring element that comprises a flat rectangular body of a resilient Material having a lower face, an upper face, four sides, patterns at its four sides that enable interlocking several similar flooring elements by form-fitting connections. Respective short straight corner sections are provided that constitute a part of the side of the concerned side. The patterns comprise alternating sequence of connection tabs and connection recesses. The connection tabs have identical profiles but inverse of the profiles of the connection recesses. A plurality of fall protecting floor elements can be connected together to form a flooring.

Apparatus and methods are provided for providing an artificial turf system having an array of integrated fibers and base arrangement. The fibers can be integrally formed with a substrate, for example, by using a molding process. The fibers can be formed to be bonded directly to the base using molecular bonds of the material that formed the base and the fibers at the same time.

A kit including a plurality of interior paving blocks and a plurality of edge paving blocks.

An interlocking paver system including polygon and spacer pavers. The polygon paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. The spacer paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. Both the polygon and spacer pavers are symmetrical about the longitudinal and transverse axes. The spacer paver is configured to selectively interlock with the polygon paver with either of the third or fourth side of the polygon paver adjacent either of the first or second side of the spacer paver and either of the first or second side of the polygon paver adjacent either of the third or fourth side of the spacer paver.

A method includes positioning one or more roadway sensors and a plurality of a networked array of light emitting diode (LED) raised pavement markers on a road. Sensors proximate the road are associated with a network of road marking controllers that cooperate to control the LEDs as vehicles drive on the road. The LEDs operate as a networked array of roadway lane marking lights. The road marking controller(s) determine a distance between a vehicle on the road and the roadway sensor, determine a dynamic condition associated with the vehicle that changes with respect to time, and lights the plurality of LEDs based at least in part on the distance between the vehicle and the roadway sensor and the dynamic condition associated with the vehicle. Dynamic conditions for operating the LED lighting scheme can include vehicle velocity, a date, a time, a weather condition proximate the vehicle, and other factors.

A paving block having interior drainage.

A method for treating a plastic block comprising using heat to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face. A method for treating a plastic block comprising using compressive force to embed a UV resistant material into an outer face of the plastic block wherein, once embedded, the UV resistant material provides a coating on the outer face.
