The array includes a plurality of tiles wherein a first tile has attachment members on three sides and complementary attachment members on the fourth side and a second tile includes two sets of adjacent sides, the first set having attachment members and the second set having complementary attachment members.

Abstract: An athletic surface having a resilient layer operatively positioned on the supporting structure including a top playing surface; and a bottom surface associated with the supporting base structure. The bottom surface associated with the supporting base structure includes a first side surface and a second side surface, both of which extend in the longitudinal direction of the layer. The said bottom surface also includes a first end surface and a second end surface, both of which extend in the transverse direction of the layer. The top playing surface of the athletic flooring system includes a drainage facilitating means associated with the top surface.

Abstract: A drainage system for use with a synthetic grass surface, the system having a base having a center portion with a first depth and a perimeter channel with a second depth being greater than the first depth, a plurality of tiles above the base, and a synthetic grass above the plurality of tiles. Also, a business method facilitates installation of a synthetic grass system which utilizes drainage tiles positioned between a stone base and the bottom of the synthetic turf, wherein a mold for manufacturing the tile is provided from the turf company to a manufacturing company located in relatively close proximity to where the synthetic turf system is to be installed.

Abstract: An airstrip shoulder-bordering surface arrangement for extending the width of existing runway and taxiway shoulders comprising a flexible water-impermeable surfacing material extending laterally of a side edge of an airstrip shoulder, an artificial grass surface adjacent the water-impermeable surfacing material, and an edge-fastening system for securing the surfacing material in position relative to the airstrip shoulder to prevent water migration therebetween, the surfacing material having a relatively smooth top surface.

Abstract: A portable synthetic grass turf assembly—that is capable of being assembled, transported, disassembled, and stored—includes a plurality of synthetic grass module units that can be laid side by side atop a base surface to provide a continuous synthetic grass surface for various activities. Each module unit includes a synthetic grass turf with an infill layer of particulate materials disposed among the synthetic grass ribbons and atop a base sheet. A barrier of synthetic ribbons extends about the perimeter of the module unit to retain the particulate material within the module unit during its transportation and storage.

Abstract: An arrestor system and method of decelerating an aircraft. The arrestor system has a base with at least one tile made of a plurality of particles being arranged such that the particles form a plurality of water drainage passageways and wherein the at least one tile has a compressive strength which will fatigue upon a force being imparted thereto which is greater than the compressive strength of the tile.

Abstract: A tile for use in a synthetic grass system. The tile is intended to be laid in the center of an area upon which the synthetic grass assembly will be installed. This allows additional tiles to be installed in a faster amount of time by creating two areas from which the tiles may be installed.

Abstract: The present invention is directed to a synthetic turf system including a backing member having a plurality of monofilament ribbons—soft and stiff—projecting there from. A layer of particulate material lies above the backing member and among the monofilament ribbons wherein the soft monofilament ribbons facilitates the stabilization or trapping of the particulate material.

Abstract: Safety improvements of airport runways and taxiways are achieved by providing a flexible, water-impermeable surfacing material on a compacted soil base directly adjacent to an edge of airstrip shoulders. A synthetic grass surface is provided on the area beyond the surfacing material so that foreign objects such as loose particles of the airstrip shoulder materials will be driven by jet blasts and run-off across the relatively smooth texture of the surfacing material and will be trapped by the synthetic grass, thereby minimizing foreign object damage to aircraft engines, particularly to those overhanging engines which extend well beyond the existing runway and taxiway shoulders.

Abstract: A synthetic grass assembly for installation on a supporting soil substrate includes a pile fabric with a flexible sheet backing and rows of upstanding synthetic ribbons representing grass blades, extending upwardly from an upper surface of the backing. An infill layer of two distinct graded courses of particulate material is disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons. A bottom course of intermixed hard sand and resilient rubber granules with substantially identical particle size distribution characteristics is installed upon the backing and a top course exclusively of resilient rubber granules is placed upon the bottom course.

Abstract: An artificial grass surface (10) suited for bordering a runway (12) of an airfield in order to reduce the presence of birds in the airfield. The artificial grass surface (10) includes a pile fabric (14) having a plurality of pile elements (20) extending from a backing mat (18) and resembling grass. A water barrier (24) is provided for preventing water from percolating to the compacted soil surface. An infilled particulate material (22) is dispersed among the pile elements (20). A stabilizer is provided to resist dislodgment of the infilled particulate material (22) at the edges of the runways by the thrust of jet engines and to keep the particulate material (22) in the pile elements (20) when the edges of the runways are vacuumed to remove silt.

Abstract: A modular synthetic grass turf assembly includes a plurality of synthetic grass units which are transportable, adapted to be laid flat on a field and fit side by side to provide a flat and continuous synthetic grass surface for activities. Each unit includes a flexible base sheet preferably with drainage grooves and bores if it is for outdoor use. A synthetic grass turf with an infill layer of particulate materials disposed interstitially between synthetic grass fibers is superposed on the base sheet to provide a grass surface with a required quality, and be fixed thereto or simply retained in place by the weight of the infill. A number of units may have irregular shapes or can be painted with different colors to illustrate letters, marks or logos. The modular synthetic grass turf assembly is conveniently transported from a storage facility to a site.
