B. Remove loose material from compacted subbase surface immediately before placing concrete. 3.2 EDGE FORMS AND SCREED CONSTRUCTION A. Set, brace, and secure edge forms, bulkheads, and intermediate screed guides for pavement to required lines, grades, and elevations. Install forms to allow continuous progress of work and so forms can remain in place at least 24 hours after concrete placement. B. Clean forms after each use and coat with form release agent to ensure separation from concrete without damage. 3.3 STEEL REINFORCEMENT A. Locate, place and support reinforcement as specified in Division 03 section, “Concrete,” unless otherwise indicated. 3.4 JOINTS A. General: Construct construction, isolation, and contraction joints and tool edgings true to line with faces perpendicular to surface plane of concrete. Construct transverse joints at right angles to centerline, unless otherwise indicated. 1. When joining existing pavement, place transverse joints to align with previously placed joints, unless otherwise indicated. B. Construction Joints: Set construction joints at side and end terminations of pavement and at locations where pavement operations are stopped for more than one-half hour, unless pavement terminates at isolation joints. 1. Provide preformed galvanized steel or plastic keyway-section forms or bulkhead forms with keys, unless otherwise indicated. Embed keys at least 1-1/2 inches into concrete. 2. Continue reinforcement across construction joints, unless otherwise indicated. 3. Use epoxy bonding adhesive at locations where fresh concrete is placed against hardened or partially hardened concrete surfaces. C. Isolation Joints: Form isolation joints of preformed joint-filler strips abutting concrete curbs, catch basins, manholes, inlets, structures, walks, other fixed objects, and where indicated. 1. Locate expansion joints at intervals of 50 feet, unless otherwise indicated. 2. Extend joint fillers full width and depth of joint. 3. Furnish joint fillers in one-piece lengths. Where more than one length is required, lace or clip joint-filler sections together. 4. Protect top edge of joint filler during concrete placement with metal, plastic, or other temporary preformed cap.

Install dowel bars and support assemblies at joints where indicated. Lubricate or asphaltcoat one-half of dowel length to prevent concrete bonding to one side of joint. E. Contraction Joints: Form weakened-plane contraction joints, sectioning concrete into areas as indicated. Construct contraction joints for a depth equal to at least one-fourth of the concrete thickness, as follows: 1. Grooved Joints: Form contraction joints after initial floating by grooving and finishing each edge of joint with groover tool. 2. Sawed Joints: Form contraction joints with power saws equipped with shatterproof abrasive or diamond-rimmed blades. Cut 1/8-inch-wide joints into concrete when cutting action will not tear, abrade, or otherwise damage surface and before developing random contraction cracks. F. Edging: Tool edges of pavement, gutters, curbs, and joints in concrete after initial floating with an edging tool. 3.5 CONCRETE PLACEMENT A. Remove snow, ice, or frost from subbase surface and reinforcement before placing concrete. Do not place concrete on frozen surfaces. B. Moisten subbase to provide a uniform dampened condition at the time concrete is placed. Do not place concrete around manholes or other structures until they are at the required finish elevation and alignment. C. Comply with requirements and with recommendations in ACI 304R for measuring, mixing, transporting, and placing concrete. D. Do not add water to concrete during delivery, at Project site, or during placement. E. Deposit and spread concrete in a continuous operation between transverse joints. Do not push or drag concrete into place or use vibrators to move concrete into place. F. Consolidate concrete by mechanical vibrating equipment supplemented by hand-spading, rodding, or tamping. Use equipment and procedures to consolidate concrete according to recommendations in ACI 309R. 1. Consolidate concrete along face of forms and adjacent to transverse joints with an internal vibrator. Keep vibrator away from joint assemblies, reinforcement, or side forms. Use only square-faced shovels for hand-spreading and consolidation. Consolidate with care to prevent dislocating reinforcement, dowels, and joint devices. G. Place concrete in two operations; strike off initial pour for entire width of placement and to the required depth below finish surface. Lay welded wire fabric or fabricated bar mats immediately in final position. Place top layer of concrete, strike off, and screed. 1. Remove and replace portions of bottom layer of concrete that have been placed more than 15 minutes without being covered by top layer, or use bonding agent if approved by Architect. 32 13 13 -7 VILLAGE ON THE GREEN -PARCEL 7C Issue Date 09.15.09 CONCRETE PAVING OFFICE BUILDING NO.1 AND BLACK BOX THEATRE; PARCEL 7-C-2 CARMEL, IN H. Screed pavement surfaces with a straightedge and strike off. Commence initial floating using bull floats or darbies to form an open textured and uniform surface plane before excess moisture or bleed water appears on the surface. Do not further disturb concrete surfaces before beginning finishing operations or spreading dry-shake surface treatments. I. Curbs and Gutters: When automatic machine placement is used for curb and gutter placement, submit revised mix design and laboratory test results that meet or exceed requirements. Produce curbs and gutters to required cross section, lines, grades, finish, and jointing as specified for formed concrete. If results are not approved, remove and replace with formed concrete. 3.6 CONCRETE FINISHING A. General: Wetting of concrete surfaces during screeding, initial floating, or finishing operations is prohibited. B. Float Finish: Begin the second floating operation when bleed-water sheen has disappeared and the concrete surface has stiffened sufficiently to permit operations. Float surface with power-driven floats, or by hand floating if area is small or inaccessible to power units. Finish surfaces to true planes. Cut down high spots, and fill low spots. Refloat surface immediately to uniform granular texture. 1. Medium-to-Fine-Textured Broom Finish: Draw a soft bristle broom across floatfinished concrete surface perpendicular to line of traffic to provide a uniform, fineline texture. 3.7 CONCRETE PROTECTION AND CURING A.
