ABSTRACT:
The present invention is directed to a weldless pavement module and a method for making a weldless pavement module. Each of the primary load bearing bars is formed with openings for receiving slotted secondary load bearing bars which are passed through the primary load bearing bars in a substantially horizontal position and which are rotated into a vertical position. The size and shape of the openings and the slots permit the combination of primary load bearing bars and secondary load bearing bars to be skewed to form a nonrectangular parallelogram configuration. Simple tack welds are used to temporarily hold the grating in its desired configuration. A concrete component encases at least the top surface of the grating base member and permanently secures the elements of the grating base member together. The use of tack welds eliminates the requirement that the grating base member be bent into a convex shape prior to welding. A simple flat jig is used.
