摘要： An erected platform which contains parallel lines of trusses connected end-to-end and method of erecting thereof, as illustrated in FIGS. 20 to 23. Each truss has two sides for chords respectively, with apertures or eyelets at the ends. First and second other trusses for a pair of parallel lines respectively are connected by positioning a first other truss adjacent the decking laid on an existing platform portion. Apertures on first respective sides of the first other truss and one of the existing trusses are connected by a first pin and the first other truss swung into an end-to-end position with the one existing truss and a second pin inserted in apertures on second respective sides of the first other truss and the one existing truss. The first pin is removed and the first other truss swung out of the way so that the second other truss may be attached. The second other truss is positioned adjacent the existing decking and similarly connected end-to-end with the other existing truss. The first other truss is then swung back into position for end-to-end attachment to the one existing truss and the second pin re-inserted.

摘要： A foldable quad-chord truss which can be connected end-to-end with like trusses. Each pair of chords are rigidly attached, and connector members intermediate the ends are swivelly attached to the chord pairs to effect the folding into a compact shape for transport and storage. The connector members are adapted for attachment to connector members of beams which may extend perpendicular to a parallel pair of the trusses and attached thereto. The laid trusses and beams is overlaid with sheets of corrugated sheet metal which overlap each other along their adjacent edges. While standing on a sheet of laid sheet metal adjacent ends of an already laid pair of trusses, another truss can be held adjacent the edge of the sheet metal for attaching an end of the other truss along only one side so that it can then be swung outwardly into a position wherein the other end of the other truss can also be attached to rigidly connect the trusses end-to-end.

摘要： A platform and a kit therefor. The platform and the kit comprises quad-chord trusses attachable end-to-end and having connector members intermediate thereof, and further comprising beams attachable at their ends to the connector members so that a beam attaches two parallel trusses. A truss comprises first and second pairs of chords which are foldable for storage and transport and unfoldable to use for erection of the platform. A track lies between the upper chords to allow movement of bolts along the track into position to attach for insertion into decking apertures for attachment of the decking. The kit also includes a sturdy and reliable and easy to use tie-up mechanism and railing along the platform perimeter which is quickly and easily attachable and reliable.

摘要： A pavement repair system is provided utilizing solid phase auto regenerative cohesion and homogenization by liquid asphalt oligopolymerization technologies. The system is suitable for use in repairing asphalt pavement, including pavement exhibiting a high degree of deterioration (as manifested in the presence of potholes, cracks, ruts, or the like) as well as pavement that has been subject to previous repair and may comprise a substantial amount of dirt and other debris (e.g., chipped road paint or other damaged or disturbed surfacing materials). A system utilizing homogenization by liquid asphalt oligopolymerization is suitable for rejuvenating or repairing aged asphalt, thereby improving properties of the paving material.
