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.

What is claimed is: 1. A temporary road element comprising: A) one-piece cage which includes (1) a longitudinal axis, (2) a transverse axis, (3) a thickness axis, (4) a first section having (a) a plurality of first rebars which extend in the direction of the longitudinal axis and which are spaced apart from each other in the direction of the transverse axis, and (b) a plurality of second rebars which extend in the direction of the transverse axis and which are spaced apart from each other in the direction of the longitudinal axis, and (c) the first and second rebars intersecting each other at first intersections and being orthogonally oriented with respect to each other, (5) a second section having (a) a plurality of third rebars which extend in the direction of the longitudinal axis and which are spaced apart from each other in the direction of the transverse axis, and (b) a plurality of fourth rebars which extend in the direction of the transverse axis and which are spaced apart from each other in the direction of the longitudinal axis, and (c) the third and fourth rebars intersecting each other at second intersections and being orthogonally oriented with respect to each other, (6) the first rebars being co-planar with corresponding third rebars, (7) the second rebars being co-planar with corresponding fourth rebars, (8) a plurality of connecting rebars which connect the intersections of the first and second rebars to corresponding intersections of the third and fourth rebars, and (9) the intersections of the rebars all being welded together so the rebars define a one-piece structure; B) a flexible mat which comprises (1) crumb rubber, (2) urethane, and (3) fiber from motor vehicle tires; and C) the flexible mat encasing the one-piece cage. 2. The temporary road element defined in claim 1 wherein the one-piece cage further includes a first plate that one-piece with one rebar of the first rebars and with one rebar of the third rebars, a second plate that is one-piece with one rebar of the second rebars and with one rebar of the fourth rebars and a third plate that is one-piece with the one rebar of the third rebars and with the one rebar of the fourth rebars. 3. The temporary road element defined in claim 1 further including a conduit which is located between the first section and the second section and which extends in the direction of the transverse axis of the one-piece cage. 4. The temporary road element defined in claim 1 wherein the flexible mat is formed by cold curing and including crumb rubber, urethane and fiber from land vehicle tires. 5. The temporary road element defined in claim 1 wherein the flexible mat is formed by a cold curing process. 6. The temporary road element defined in claim 1 wherein the flexible mat is formed by a process which includes steps comprising providing a mold, forming a mixture of crumb rubber, urethane and fibers from land vehicle tires, applying pressure to the mixture, and cold curing the mixture. 7. A temporary road element comprising: A) a one-piece cage which includes first and second layers of orthogonally arranged rebars and a plurality of connecting rebars which connect rebars of the first layer to rebars of the second layer; and B) a flexible mat which encases the one-piece cage, the flexible mat being flexible mat is formed by a process which includes steps comprising providing a mold, forming a mixture of crumb rubber, urethane and fibers from land vehicle tires, applying pressure to the mixture, and cold curing the mixture. 8. The temporary road element defined in claim 7 further including a plurality of plates which are one-piece with one rebar in the first layer and one rebar in the second layer. 9. The temporary road element defined in claim 8 further including another plate which is one piece with two rebars in the second layer. 10. A temporary road element formed by a process which comprises: A) forming a one-piece cage which includes a longitudinal axis, a transverse axis, a thickness axis, a first section having a plurality of first rebars which extend in the direction of the longitudinal axis and which are spaced apart from each other in the direction of the transverse axis, and a plurality of second rebars which extend in the direction of the transverse axis and which are spaced apart from each other in the direction of the longitudinal axis, and the first and second rebars intersecting each other at first intersections and being orthogonally oriented with respect to each other, a second section having a plurality of third rebars which extend in the direction of the longitudinal axis and which are spaced apart from each other in the direction of the transverse axis, and a plurality of fourth rebars which extend in the direction of the transverse axis and which are spaced apart from each other in the direction of the longitudinal axis, and the third and fourth rebars intersecting each other at second intersections and being orthogonally oriented with respect to each other, the first rebars being co-planar with corresponding third rebars, the second rebars being co-planar with corresponding fourth rebars, a plurality of connecting rebars which connect the intersections of the first and second rebars to corresponding intersections of the third and fourth rebars, and the intersections of the rebars all being welded to so the rebars define a one-piece structure; and B) forming a flexible mat by providing a mold, forming a mixture of crumb rubber, urethane and fibers from land vehicle tires, pouring part of the mixture into the mold, placing the one-piece cage on the mixture, pouring in another part of the mixture onto the cage and encasing the cage in the mixture, applying pressure to the mixture covered cage, and cold curing the mixture covered cage.
