Prepare and patch with hot -mix <br />asphalt. <br />C. Leveling Course: Install and compact leveling course consisting of dense -graded, hot- <br />mix asphalt surface course to level sags and fill depressions deeper than 1 inch in <br />existing pavements. <br />1. Install leveling wedges in compacted lifts not exceeding 3 inches thick. <br />D. Crack and Joint Filling: Remove existing filler material from cracks or joints to a depth <br />of 1/4 inch. Refill with asphalt joint-filling material to restore watertight condition. <br />Remove excess filler that has accumulated near cracks or joints. <br />3.4 SURFACE PREPARATION <br />A. General: Immediately before placing asphalt materials, remove loose and deleterious <br />material from substrate surfaces. Ensure that prepared subgrade is ready to receive <br />paving. <br />1. Sweep loose granular particles from surface of unbound -aggregate base course. <br />Do not dislodge or disturb aggregate embedded in compacted surface of base <br />course. <br />3.5 HOT-MIX ASPHALT PLACING <br />A. Machine place hot-mix asphalt mix on prepared surface, spread uniformly, and strike <br />off. Place asphalt mix by hand to areas inaccessible to equipment in a manner that <br />prevents segregation of mix. Place each course to required grade, cross section, and <br />thickness, when compacted. <br />1. Spread mix at minimum temperature of 250 deg F. <br />2. Begin applying mix along centerline of crown for crowned sections and on high <br />side of one-way slopes, unless otherwise indicated. <br />3. Regulate paver machine speed to obtain smooth, continuous surface free of pulls <br />and tears in asphalt-paving mat. <br />B. Place paving in consecutive strips not less than 10 feet wide, except where infill edge <br />strips of a lesser width are required. <br />1. After first strip has been placed and rolled, place succeeding strips and extend <br />rolling to overlap previous strips. Complete asphalt base course for a section <br />before placing asphalt surface course. <br />C. Promptly correct surface irregularities in paving course behind paver. Use suitable <br />hand tools to remove excess material forming high spots. Fill depressions with hot -mix <br />asphalt to prevent segregation of mix; use suitable hand tools to smooth surface. <br />3.6 JOINTS <br />A. Construct joints to ensure continuous bond between adjoining paving sections. <br />Construct joints free of depressions with same texture and smoothness as other <br />sections of hot-mix asphalt course. <br />1. Clean contact surfaces and apply tack coat. <br />2. Offset longitudinal joints in successive courses a minimum of 6 inches. <br />3. Offset transverse joints in successive courses a minimum of 24 inches. <br />4. Construct transverse joints by bulkhead method or sawed vertical face method as <br />described in AI's "The Asphalt Handbook." <br />Docusign Envelope ID: 34F94CE0-2CE8-49C5-B7C4-6B696F8E23C3
