Highway Paving Concrete Jointed Slabs

Placing time is reduced and over steeling avoided when you use Welded Wire Reinforcement in your paving project. Ivy Steel & Wire has manufacturing capabilities to produce flat sheets of mesh up to 13 feet wide and 40 feet long in either plain or deformed WWR. This allows designers to specify the horizontal and vertical spacing of the wires along with the size of the wires, to produce a precise reinforcing plan for reinforced pavement for City Streets, State and Federal Highways, Airport Runways and Parking Lots. For more information, please refer to WWR-101:  Jointed Concrete Pavements Reinforced with Welded Wire Reinforcement 1982, 5th Printing, 40 pages.

Jointed Slabs

The ability to design a paving sheet that can vary in size to fit the joint spacing, saves time and money in jointed slabs. Welded Wire Reinforcing from Ivy Steel & Wire controls cracking by placing steel where it is needed and to assure accurate placement. The main purpose of the WWR is not to prevent cracking, but to keep cracks that form held together. The pavement will then carry its design load as though it had not cracked.

In jointed slabs, the amount of reinforcing is sometimes selected by the traditional sub grade drag theory. In this method, the joint spacing, friction of the sub grade, yield strength of the steel, thickness of the slab and the loading requirements, determine the amount of steel to be used.

Welded Wire Reinforcement can provide the necessary steel required for the pavement to perform properly and allow the designer to go to longer joint spacing. With fewer joints, the costs associated with maintenance of the joints are greatly reduced.
