518.3(c) 518.4(c) than 2 inches or damage to existing reinforcement bars occurs, make a new full -depth, transverse saw-cut beyond the area of break back. Saw cut a new outside edge, maintaining the appropriate bar length at the edge of patch. Place the additional length of patch at no additional cost to the Department. If the existing pavement was constructed on top of a bond breaker, remove the bond breaker from the top of pavement base. Place two layers of 4.0 mil minimum polyethylene sheeting to be used as a new bond breaker before placing concrete. Cut the polyethylene sheeting to the surface dimensions of the patch. If the surface of the subbase is disturbed by the removal procedure, recompact the surface using small vibratory compactors. If subbase material is disturbed to a depth greater than 1 inch, remove the disturbed material with hand tools and replace with concrete during paving at no additional cost to the Department.
as shown on the Standard Drawings . Firmly support and tie bars at every intersection to re-establish the continuous reinforcing. Use tied or welded splices. Lap the new reinforcement bars with the existing bars as shown on the Standard Drawings for the type of rebar splices to be used. Weld splice as specified in Section 1105.03(m) and as shown on the Standard Drawings . When weld splicing, lap tie bars at the center of the patch, as shown on the Standard Drawings , to allow for expansion.
