Abstract:
An on-site joint forming process in concrete paving comprising:a) providing a plurality of wires, each of said wires comprising a first elongate portion that is disposable along a surface to be paved and a second portion that is disposed at an angle relative to said first portion; b) placing the plurality of wires on the surface to be paved at a site at which a joint is to be formed with a first set of the plurality of wires in a first zone of the site and a second set of the plurality of wires in an adjoining zone of the site and with the first set of the wires disposed along the surface in a first direction and the second set of the wires disposed along the surface in an opposite direction, said plurality of wires being constructed and disposed with respect to one another such that, upon pouring of concrete over the plurality of wires and shrinking of the poured concrete, a joint is formed between adjoining concrete slabs with the slabs having a periodic arrangement of protrusions and recessions that prevents vertical movement between the slabs; and (c) pouring concrete over the plurality of wires and allowing the poured concrete to shrink with formation of the joint and adjoining concrete slabs.
