PennDOT - 12-22-GR4 *The value for this project is based on a financial range. The value is listed as the highest possible cost from the range provided by a stakeholder or official project document. This work consists of the replacement, repair, and maintenance of guide rail systems, including all appurtenances and hardware 1. General - All areas to be repaired will be delineated by the Representative. 2. Removal - Sawcut around the periphery of the delineated repair and remove the deteriorated concrete within the boundaries behind reinforcement to sound concrete (but a minimum of 1 inch). Remove concrete to undercut the sawcut periphery of the repair to dovetail the repair concrete into the existing concrete. Do not use pneumatic hammers exceeding an impact rating of 30 foot-pounds. Use hand tools such as hammers and chisels, or small air chisels (maximum of 30 pounds), to remove loose particles of unsound concrete or to provide necessary clearances around reinforcement bars. After removal of concrete, clean the concrete surface within the removal limits to remove partially loosened chips. 3. Reinforcement - Clean all exposed reinforcement to remove all rust. Install, in kind, portions of damaged or heavily corroded reinforcement (reinforcement with 25 percent loss or more) with the same size reinforcement. Splice new bars to the deteriorated reinforcement with lengths as shown on the Standard BC Drawing. Place new reinforcement that matches the properties of the existing reinforcement as directed. All new reinforcement shall be epoxy coated. Where exposed existing reinforcement is bowed outward, bend it back into concrete member. Coat all existing reinforcement with an epoxy paint before placement of concrete. 4. Concrete Placement - Set forms as indicated to provide minimum concrete cover. Maintain all chamfers. Provide adequate ports for applying epoxy bonding compound and placement of repair concrete. Use removable forms. Clean all removal areas with oil-free compressed air and protect against any contaminant detrimental to the bond of the new concrete. Immediately prior to placing new concrete, apply epoxy-bonding compound to the area of existing concrete that will be in contact with the new concrete. Coat the existing exposed reinforcement. Place concrete against the epoxy while it is still sufficiently tacky to provide a proper bond. Recoat epoxy that is no longer tacky. Remove epoxy that has hardened before recoating. The cost of cleaning and epoxy-bonding compound is incidental. Place concrete as specified in Section 1001.3. Use water cure as specified in Section 1001.3. Membrane curing is not allowed. Place joint sealing material between concrete and masonry plate as indicated or as directed.
