Thoroughly clean existing drainage troughs to remove of all debris. Clean and paint all exposed metal where noted on the PlansThe official drawings issued by the Administration as part of the Contract Documents, including those incorporated in the Contract Documents by reference. or as directed.
All angles shall be cut with a saw. All holes and slots shall be drilled. Do not cut with a torch.

After the joints are complete in place and just prior to placing the compression seal, remove the masking tape and residue, and install the seal. Then apply the finish coat to the exposed portion of the angles above the seal.
Joint Seals in BridgeA structure including supports erected over a depression or an obstruction, such as water, highway, or railway, and having a track or passageway for carrying traffic or other moving loads, and having an opening measured along the center of the roadway of more than 20 feet between undercopings of abutments or spring lines of arches, or extreme ends of openings for multiple boxes; it may also include multiple pipes, where the clear distance between openings is less than half of the smaller contiguous opening. For lengths, all dimensions shall be parallel to the center line of the roadway. The dimensions of handrails will not be taken into account in measuring bridge lengths. Any bridge or highway grade separation structure includes the connecting highways, substructure, superstructure, roadway approaches, entrance plazas, interchanges, overpasses, underpasses, and other structures which the Administration may deem necessary together with all property rights, easements, franchises, and interests acquired by the Administration for the construction and operation of the bridge. Decks. Place transverse compression seals in one piece for the entire length of the roadway joint. Shop and field splices are prohibited. Use the longest compression seal pieces as practicable for longitudinal bridge joints.
Apply the lubricant adhesive according to the manufacturer’s recommendations. If the seal is stretched in excess of 5 percent, remove and reinstall the seal as directed.
460.03.01 In-Place Testing. Subject the completed joint to a water test to detect any leakage. Conduct the test at least five days after completing the joint. Provide all facilities required for the EngineerAny person designated by the Administrator or the procurement officer, acting directly or through his duly authorized representative, such representative acting within the scope of the particular duties assigned to him or of the authority given him.’s inspections of the underdeck areas. Cover the roadway section of the joint from curb to curb, or parapet to parapet, with at least 1 in. of water. If this is not possible, perform the water test in part section along the joint. When testing subsequent part sections, overlap at least 1 ft of the joint previously tested.
Maintain the ponding for a period of five hours for the entire roadway or each section of joint being tested. During and at the conclusion of the test, examine the underside of the joint for leakage. The expansion joint seal will be considered watertight if no obvious wetness is visible. If the joint system exhibits evidence of water leakage at any point, locate and repair all leaks.
When repairs are required, perform a subsequent water test.
If the joint leaks after the second test, remove, replace, and retest the seal.
