Abstract: An automated system for creating a road from sand, gravel or aggregate in conjunction with expandable webbing is provided in which expandable webbing and sand, gravel or aggregate may be positioned and deployed by the system to form a road surface. A series of pins may restrain and transport the webbing. An automatic welder may connect sections of webbing. A hopper, conveyor and auger may receive and distribute the sand, gravel or aggregate. The sand, gravel and aggregate may be combined with the expandable webbing and then settled into place in the ground using a vibration plate.

Abstract: A mat with an upper road side and a lower ground contacting side, the mat comprising: a frame supporting one or more boards; and a grapple receiver formed in an interior portion of the mat and indented from one or both of the upper road side and the lower ground contacting side to allow grapple jaws to grip the grapple receiver between the grapple jaws.

Abstract: A combination of a buried pipeline and a pipeline crossing bridge, the pipeline crossing bridge comprising: a first ground contacting pad and a second ground contacting pad spaced apart from one another; plural ribs with lateral stabilizing elements between adjacent ribs of the plural ribs, in which each rib of the plural ribs is supported on the first ground contacting pad and the second ground contacting pad and the ribs collectively form a raised arch extending between the first ground contacting pad and the second ground contacting pad; an upper crossing surface supported by the plural ribs, in which the pipeline crossing bridge is positioned over the buried pipeline, and in which the buried pipeline has a diameter, and the first ground contacting pad and the second ground contacting pad are spaced apart wider than the diameter of the buried pipeline.

Abstract: A bridge comprising first and second ground contacting pads spaced apart from one another; plural ribs with lateral stabilizing elements between adjacent ribs of the plural ribs, each rib of the plural ribs being supported on both the first and second ground contacting pads and the ribs collectively forming an arch extending between the first and second ground contacting pads; and an upper crossing surface supported by the plural ribs.

Abstract: A bridge comprising a first ground contacting pad and a second ground contacting pad spaced apart from one another, three or more ribs with lateral stabilizing elements extending between adjacent ribs of the three or more ribs, and an upper crossing surface supported by the three or more ribs. Each rib of the three or more ribs is supported on the first and second ground contacting pads. Each of the first and second ground contacting pads extends underneath each rib of the three or more ribs. The ribs collectively form an arch extending between the first and second ground contacting pads.

Abstract: A road element is formed of a one-piece cage that includes two layers of orthogonally arranged rebars which are welded together. The layers are connected by connecting rebars that are welded to the rebars of the layers at the intersections and the one-piece cage is encased in a flexible material formed of crumb rubber, urethane, and fibers from land vehicle tires. Plates can be included with the one-piece cage to further enhance the strength of the element.
