Section 418. — ASPHALT CONCRETE PAVEMENT PATCHING
Description
418.01 This work consists of repairing distressed areas of asphalt concrete pavement by removing and patching the pavement and underlying material as required.
Separation and stabilization geotextile is designated according to Table 714-1.
Material
418.02 Conform to the following Sections and Subsections:
Asphalt concrete 403 Asphalt tack coat 412 Crushed aggregate 703.06 Separation and stabilization geotextile and geotextile filter 714.01(a) Stabilization geogrid 714.03
Construction Requirements
418.03 Asphalt Pavement, Base, and Subgrade Full Depth Patch, Type 1 (FDP-1).
(a) Patch areas. Extend the repair area 12 inches (300 millimeters) beyond the distressed area.
If patch limits are within 24 inches (600 millimeters) of the pavement edge, extend the patch limit to the pavement edge. Make the minimum transverse dimension of the patch half of the travel lane width and the minimum longitudinal dimension of the patch 36 inches (900 millimeters).
(b) Pavement removal. Mill completely through the pavement or saw cut and remove the pavement. When saw cutting, cut through the existing pavement and around the perimeter of the patch area. Make saw cuts perpendicular to the roadway surface and at right angles to each other. Remove the pavement, base and subgrade to the depth shown in the plans.
(c) Patching. When required, place geogrid or geotextile according to Section 207. Place and compact crushed aggregate base according to Subsections 302.04 and 302.05. Asphalt millings may be used for crushed aggregate base material. Apply a tack coat to the edges of the patch area according to Section 412. Place and compact asphalt concrete pavement to ensure the patched surface matches the same grade as the adjacent surface.
418.04 Asphalt Pavement Full Depth Patch, Type 2 (FDP-2).
(a) Patch areas. Extend the repair area 12 inches (300 millimeters) beyond the distressed area.
If patch limits are within 24 inches (600 millimeters) of the pavement edge, extend the patch limit to the pavement edge. Make the minimum length and width of the patch 36 inches (900 millimeters).
(b) Pavement removal. See Subsection 418.03(b), except remove the pavement to expose subbase or subgrade as shown in the plans.
(c) Patching. Apply a tack coat to the edges of the patch area according to Section 412. Place and compact asphalt concrete pavement so the patched surface matches the same grade as the adjacent surface.
418.05 Asphalt Pavement Partial Depth Patch, Type 3.
(a) Patch areas. Patch areas will be designated by the CO.
(b) Pavement removal. Clean the patch area by sweeping or other acceptable methods.
(c) Patching. Apply a tack coat to asphalt concrete surfaces within the patch area according to Section 412. Place the asphalt material either by hand, with a blade, or other approved method. Compact the asphalt concrete pavement patch to match the grade of the adjacent surface.
418.06 Disposing of Waste. Dispose of debris and unsuitable and excess material according to Subsection 203.05(a) and (d).
418.07 Acceptance. Construction of asphalt concrete pavement patching will be evaluated under Subsections 106.02 and 106.04.
Separation and stabilization geotextiles and geogrid will be evaluated under Subsections 106.02 and 106.03.
Asphalt concrete will be evaluated under Section 403.
Crushed aggregate will be evaluated under Section 302.
Asphalt tack coat will be evaluated under Section 412.
Measurement
