Waterproof membrane materials, if present, shall be removed as required. If a steel plate is present, it shall be replaced with a new plate, as shown on the plans. Any concrete repair work required to provide a level surface between both sides of the expansion gap, shall be paid for in accordance with 109. 04. All concrete, steel, and asphalt joint surfaces shall be prepared and treated as recommended by the Manufacturer’s technical representative. 3.4.3 For the asphaltic plug for crack control, sawcut and completely remove the asphalt and membrane or existing asphaltic material as shown on the plans, to create a neatly formed blockout. The bottom of the blockout shall be level with the top of the deck concrete. The blockout area above the deck concrete shall be free of asphalt, and the blockout area over approach roadw ay asphalt shall be blast cleaned to be free of loose asphalt debris. The joint area shall be thoroughly dried using hot compressed air immediately prior to applying the asphaltic material. 3.4.4 The backer rod shall continue into the curb gap and be placed at a uniform depth following the geometry of the curb for placement and tooling of sealant as shown on the plans. The bridge asphaltic joint shall be completely cool before installation of the curb sealant over the backer rod. 3.4.5 The asphaltic material shall be heated, mixed and placed in two (2) lifts using machinery and/or equipment supplied or recommended by the Manufacturer. 3.4.6 Placement, screeding, and compaction of the asphaltic plug material shall be as recommended by the Manufacturer. Compaction shall be accomplished utilizing plate compactors or rollers. 3.4.7 A skim coat of liquid asphaltic binder material shall be applied to fill any remaining surface voids. 3.4.8 To prevent joint damage from tire traffic, shot blast media (clean, unused) shall be broadcast onto t he finished joint surface while the asphaltic material is still warm. 3.4.9 The application of the asphaltic binder and the asphaltic material shall be performed only if : 1) The surface temperature is a at least of 40° F and rising, 2) The road surface is dry, 3) Weather conditions are favorable with no signs of imminent rain. 3.4.10 Protect the joint from traffic until the material has cooled to 125° F± and is able to support traffic.
