摘要:
A pavement slab includes a top surface, a bottom surface opposite the top surface, first and second longitudinal side surfaces, each of which extends from the top surface to the bottom surface, and first and second transverse side surfaces, each of which extends from the top surface to the bottom surface. At least one transverse tube is positioned intermediate the top surface and the bottom surface and extends from an inlet at the first longitudinal side surface to a second end intermediate the first and second longitudinal side surfaces. The at least one transverse tube is sized and shaped to convey a binder material. At least one vertical tube extends from each of the at least one transverse tube to the bottom surface. The at least one vertical tube is sized and shaped to convey the binder material.

An arcuate tactile sidewalk tile arrangement includes a connector tactile sidewalk tile including a wedge-shaped main body and one or more connector flanges that adjoin one or more longitudinal sides of the wedge-shaped main body. One or more rectilinear tactile sidewalk tiles overlap the one or more connector flanges. A plurality of truncated domes projects upwardly in a vertical direction from an upper surface of the wedge-shaped main body, as well as an upper surface of each one of the one or more rectilinear tactile sidewalk tiles.
摘要:
A traction device that provides increased traction of a tire on a poor tractional surface. The traction device includes a base and a top cover. The base has a main portion, a pair of short side portions, and a plurality of traction blocks. The top cover is affixed to the base. The pair of short side portions of the base are serrated to facilitate engaging under the tire and are separate from the main portion of the base to increase flexibility of the top cover. The plurality of traction blocks of the base are affixed to the base and increase traction of the tire on the poor tractional surface when the poor traction surface is at least one of mud and snow.
摘要:
Methods of manufacturing a plurality of mats useful with a plurality of frame style seal members in a load-supporting surface include at least one milling machine, router or pre-formed mold forming at least first and second elongated grooves in first and second offset outer edges of at least a first side of each among at least first and second stepped-configuration, reversible mats. Each groove causes the seal member(s) seated therein to extend into a gap formed between the mats, abut at least one seal member extending from another mat into the same gap and form a liquid-tight seal therewith.
摘要:
A portable pathway apparatus for providing a path over a surface, the portable pathway comprising: a pliable frame member; a row of mating holes disposed on each side of the pliable frame member; a set of steps coupled to the pliable frame member; wherein one or more of the set of steps is coupled to the pliable frame member with a mount that aligns with the row of mating holes on each of the corresponding sides of the pliable frame member.
摘要:
A method of facilitating monitoring and interdicting of targets crossing through an area comprising first mixing a luminescent pigment and a soil stabilizer, second loading the mixture into a spray dispenser, third dispensing the mixture in a substantially continuous coating covering a swathe of ground, and fourth monitoring said continuous coating covering said swathe of ground for disturbances in the continuity of said swathe.
摘要:
A method for installing artificial turf at an airport or airfield includes removing or milling a portion of an airport runway or taxiway to create a new surface of the runway or taxiway, adhering a section of artificial turf to the new surface of the runway or taxiway and applying an infill to at least a portion of the artificial turf. An artificial turf system for an airport includes an airport runway or taxiway having a removed or milled surface, an artificial turf is adhesively secured to the new, milled surface of the airport runway or taxiway and an infill layer installed on at least a portion of the artificial turf.
摘要:
An airport runway arrangement for commercial aircraft is provided. The arrangement comprises a first runway section, a second runway section extending substantially in prolongation of the first runway section and an intermediate section between the first and second runway sections.
