519.1DESCRIPTION—This work is the full depth longitudinal repair of an existing concrete pavement. If
diamond grinding is to be performed, test the pavement surface in the longitudinal direction as specified in Section 514.3(d)2.
519.2MATERIAL—Section 501.2 with the following addition:
519.3CONSTRUCTION—As shown on the Standard Drawings, as specified in Section 501.3 and as follows:
106.03(a)2.a and submit it for review. Describe the construction equipment, personnel, and methods
necessary to construct and test concrete for all pav ement repair operations. Include testing frequencies, and action points to initiate corrective measures. Do not establish action points at either the upper or lower specification limits. If constructing full or partial depth patching adjacent to longitudinal joint repairs, construct all patches before performing longitudinal repairs. For any full depth repair adjacent to the longitudinal joint, the patch should be combined with the longitudinal repair along that portion of the j oint repair. The Representative will surface mark repair areas in advance of the sawing operations. After saw cutting the existing pavement, allow traffic on repair areas of existing pavement for a maximum of 72 hours. Do not allow saw cuts greater than 1/2 inch in width to be opened to traffic. Do not allow excavated repair areas to remain un-patched for more than 48 hours or over weekends or holidays. Protect traffic from drop off conditions as specified in Section 901.3(j). Before placing concrete, ensure adequate equipment and trained personnel are available, and sufficient hauling units scheduled, to maintain continuity in placement.
cooling system, and cut-depth controls for saw cutting the perimeter of the patch. Do not allow cooling water, slurry, and dust from the sawing operation to enter any la ne opened to traffic. Make all required full depth longitudinal saw cuts along the perimeter of the repair before making any full depth transverse saw cuts. Make the saw-cuts parallel to the existing longitudinal joint. Make full depth transverse saw -cuts at the locations marked on the pavement surface . Do not break back the underside of the existing pavement. If break back or spalling occurs, make a new full depth transverse saw-cut beyond the area of break back or spalling. Place the additional length of repair at no additional cost to the Department. Full depth saw cuts at the repair limits will be allowed to extend transversely into the adjacent pavement up to full depth + 2 inches provided dowel bars in the adjacent lane are not damaged. Additional full depth transverse saw cuts will be allowed to facilitate slab removal but may not extend transversely into the adjacent pavement to remain in place.
a proposed repair area in a manner that does not damage any adjacent pavement that is to remain in place. Remove the concrete in the repair area in one or more pieces minimizing disturbance to the subbase, subgrade, and the adjacent pavement to remain in place . Do not use drop hammers or hydro-hammers. If damage occurs to pavement to remain in place, repair as specified in Section 516.3(b) at no additional cost to the Department. If the surface of the subbase is disturbed by the removal technique, recompact the surface using small vibratory compactors. If the disturbed material is deeper than 1 inch, remove the disturbed material with hand tools and replace with concrete during paving at no additional cost to the Department. Correct all subbase surface irregularities exceeding 1 inch in depth by loosening the surface and removing or adding material as required. Compact the corrected area and surrounding surface by rolling to proper grade and slope.

match the existing pavement cross section.
this work, as specified in Section 501.3(n). Do not saw and seal the patch perimeter. Seal all saw-cuts extending beyond the patch limits.
519.4MEASUREMENT AND PAYMENT—
When longitudinal joint cleaning and sealing is part of the contract, the sealing of longitudinal joints is incidental to that item, not to longitudinal concrete joint repair. The unit price includes removal of the existing pavement and all repairs or corrections as specified in Section 519.3 that are needed as a result of patching operations.
The unit price includes excavation.
