Description
Summary:Epoxy-coated bars were researched by the National Bureau of Standards before being installed initially 15 years ago. Now, 46 of 50 state highway agencies use epoxy-coated bars in their bridges. The bars are used in parking garages, port and marine structures, and wastewater treatment plants, in addition to being installed in continuously reinforced pavement. Total usage of epoxy-coated bars in the US in 1987 was about 180,000 tons. Properly applied coatings are tough and flexible, and they adhere so well to the bars that coated bars can be shop-fabricated into the standard hooks and typical bends that are used for uncoated bars. It was appropriate to extend the technology of epoxy-coated reinforcing bars to the coating of welded wire fabric. Now, coated fabric is used for corrosion protection in precast prestressed members, topping slabs and overlays, bridge decks, and reinforced earth construction, such as mechanically stabilized embankments.
