before final inspection and resolution of all issues regarding the condition of the pavement, remove and replace the pavement at no additional cost to the Department. If any patch is replacing an existing expansion joint, and the existing expansion joint in the adjacent lane is remaining in place, install 3/4 -inch expansion joint material in the joint nearest to the remaining expansion joint. Apply bond breaker lubricant to at least one -half of the length of Type B coated dowel bars unless a bond breaker lubricant has been applied in the shop. Stir the lubricant well and apply to the free end of dowels by spraying, or with a gloved hand, to produce a thorough coating. Do not use brushes for lubricant application. Apply the bond breaker lubricant, as specified, at least 1 hour before placing the concrete around the dowel. Provide a tube with a minimum 1 -inch clearance packet, over the lubricated end of all coated dowel bars. Type A coated dowel bars do not need lubricant. For corner repairs, install 1/2 -inch expansion joint material to reestablish original transverse joint location. Drill 5/8 -inch diameter holes and install tie bars as shown on the Standard Drawings.
Provide holes a maximum of 1/8 inch larger in diameter than the coated dowel bars. Mount drilling machines in a frame that maintains the proper horizontal and vertical ali gnment during drilling. Do not use handheld drills or drills that rest upon the subbase or subgrade. Drill holes to ensure the dowel alignment tolerances shown on the Standard Drawings and as specified in Section 501.3(i) . Change location of drill holes ±1 inch to avoid existing reinforcing steel. Securely embed the coated dowel bars into place with an approved anchoring material. Inject all the mixed anchoring material into the rear of the hole before inserting the dowel bar. Rotate the dowel three to five complete rotations while inserting the dowel to purge air voids as completely as possible. Immediately trowel all excess anchoring material flush with the vertical face of the patch until the anchorin g material reaches its initial set. Do not leave voids in the anchoring material. Use a plastic retainer washer to hold anchoring material in place, if directed, and remove before placement of concrete in the patch. Provide anchoring material formulated to reach an initial set within 5 minutes of application. Provide a material specification data sheet for the anchoring materi
