253Pavement Repair

253.01 Description. This work consists of removing existing asphalt concrete, brick, Portland

cement concrete, or aggregate pavement courses; shaping and compacting the exposed material; and placing new asphalt concrete pavement or aggregate and asphalt concrete pavement courses. The plans show details about the repairs and replacement material.

253.02 Removal of Existing Pavement. The Engineer will designate the location and limits of

areas to be repaired. Provide the Engineer with aerosol spray paint to outline those areas for repairs. Repair the full depth of the pavement, unless otherwise shown on the plans. Cut the existing pavement at the limits specified and as necessary to prevent disturbing or undermining the remaining pavement during removal. Completely remove pavement in the repair area to the specified depth without displacing, undermining, or otherwis e damaging the remaining pavement. Dispose of removed pavement according to 202. Trim the limits of the repair to form a vertical face 1.5 inches (38 mm) deep from the surface unless the repair is covered with an overlay within 60 days.

253.03 Placement of Asphalt Concrete. Shape and compact the exposed underlying material as

the Engineer directs. Before placing asphalt concrete, clean all vertical faces of the existing pavement and coat them with asphalt material according to 401.06. Place the replacement material in lifts as the Engineer directs. Thoroughly and uniformly compact each lift using suitable compaction equipment as the Engineer directs. Finish the final lift flush with the adjacent pavement surface. Thoroughly compact the final lift using a pneumatic tire roller conforming to 449.02. As the rolling progresses, add additional asphalt concrete, as necessary, to produce a smooth surface flush with the adjacent pavement surface. Continuously compact each lift while the material is in a workable condition throughout the depth of the lift. Ensure that each lift is thoroughly compacted to a suitable density that will not result in displacement under traffic. If the Contract does not include resurfacing, seal the perimeter surface of the repaired area by applying a 2 to 4 inch (50 to 100 mm) wide strip of approved 705.04 material or 702.01 approved PG binder. After completing repairs, restore the existing shoulders to the condition that existed prior to the repair work.

253.04 Method of Measurement. The Department will measure the quantity of Pavement

Repair by either the number of square yards (square meters) or cubic yards (cubic meters) of pavement repaired in the complete and accepted work, calculated using the dimensions established by the Engineer.

253.05 Basis of Payment. Payment is full compensation for furnishing all materials, including

aerosol spray paint and replacement and restoration materials; cutting, removing, and disposing of existing pavement; shaping and compacting the exposed underlying material; placing new pavement; and restoring the shoulders. The Department will not pay for additional work to repair damage caused by the pavement sawing or pavement removal. The Department will pay for accepted quantities at the contract prices as follows: Item Unit Description 253 Square Yard Pavement Repair (Square Meter) 253 Cubic Yard Pavement Repair (Cubic Meter)
