252.01 Description. This work consists of the full depth removal of existing rigid pavement,
correcting the subgrade, placing and compacting asphalt concrete, and restoring the shoulders.
252.02 Removal of Existing Rigid Pavement . Conform to 255.03, except the last paragraph
does not apply.
252.03 Correction of Subgrade . Shape and recompact the subgrade as the Engineer directs.
Clean all vertical faces of the existing pavement, and coat them with asphalt material according to 401.06.
252.04 Placement of Asphalt Concrete. Construct the pavement replacement by placing and
compacting Item 301, 441 Type 2, or 442 19 mm material in two or more lifts according to 449.03. Thoroughly and uniformly compact all lifts before the final lift using suitable mechanical compaction equipment operated over the entire replacement area. 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. 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. 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 shoulders to the condition that existed prior to the repair work.
252.05 Method of Measurement. The Department will measure the quantity of Full Depth Rigid
Pavement Removal and Flexible Replacement by the number of square yards (square meters) of rigid pavement repaired in the complete and accepted work, calculated using the dimensions established by the Engineer. The Department will measure the quantity of Full Depth Pavement Sawing by the number of feet (meters) of full depth saw cuts in the complete and accepted work. The Department will not measure offset saw cuts. The Department will not measure additional cuts made to facilitate the removal of the pavement
252.06 Basis of Payment. Payment is full compensation for furnishing all materials, including
aerosol spray paint, removing pavement, correcting the subgrade, placing flexible pavement, sealing, and restoring the shoulders. Include the cost of removal, disposal, and replacement of pavement damaged adjacent to the repair area in the contract unit price for Full Depth Rigid Pavement Removal and Flexible Replacement. Include the cost of any additional concrete sawing and removal depths less than 1 inch (25 mm) greater than those shown in the plans. The Department will pay for accepted quantities at the contract prices as follows: Item Unit Description 252 Square Yard Full Depth Rigid Pavement (Square Meter) Removal and Flexible Replacement 252 Foot (Meter) Full Depth Pavement Sawing
