2. Provide tie bars at sides of paving strips where indicated. 3. Butt Joints: Use [bonding agent] [epoxy-bonding adhesive] at joint locations where

fresh concrete is placed against hardened or partially hardened concrete surfaces. 4. Keyed Joints: Provide preformed keyway-section forms or bulkhead forms with

keys unless otherwise indicated. Embed keys at least 1-1/2 inches into concrete. 5. Doweled Joints: Install dowel bars and support assemblies at joints where

indicated. Lubricate or coat with asphalt one-half of dowel length to prevent concrete bonding to one side of joint.

C. Isolation Joints: Form isolation joints of preformed joint-filler strips abutting concrete curbs, catch basins, manholes, inlets, structures, 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. Terminate joint filler not less than 1/2 inch or more than 1 inch below finished

surface if joint sealant is indicated. 4. Place top of joint filler flush with finished concrete surface if joint sealant is not

indicated. 5. Furnish joint fillers in one-piece lengths. Where more than one length is required,

lace or clip joint-filler sections together. 6. During concrete placement, protect top edge of joint filler with metal, plastic, or

other temporary preformed cap. Remove protective cap after concrete has been placed on both sides of joint.

152


D. 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[, to match jointing of existing adjacent concrete paving]:

1. Grooved Joints: Form contraction joints after initial floating by grooving and finishing

each edge of joint with grooving tool to a [1/4-inch] [3/8-inch] radius. Repeat grooving of contraction joints after applying surface finishes. Eliminate grooving-tool marks on concrete surfaces.

a. Tolerance: Ensure that grooved joints are within 3 inches either way from

centers of dowels.

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.

a. Tolerance: Ensure that sawed joints are within 3 inches either way from

centers of dowels.

3. Doweled Contraction Joints: Install dowel bars and support assemblies at joints where indicated. Lubricate or coat with asphalt one-half of dowel length to prevent concrete bonding to one side of joint.

E. Edging: After initial floating, tool edges of paving, gutters, curbs, and joints in concrete

with an edging tool to a [1/4-inch] [3/8-inch] radius. Repeat tooling of edges after applying surface finishes. [Eliminate edging-tool marks on concrete surfaces.]

3.6 CONCRETE PLACEMENT

A. Before placing concrete, inspect and complete formwork installation, steel reinforcement, and items to be embedded or cast-in.

B. Moisten sub-base to provide a uniform dampened condition at time concrete is placed. Do not place concrete around manholes or other structures until they are at required finish elevation and alignment.

C. Comply with ACI 301 requirements for measuring, mixing, transporting, and placing concrete.

D. Do not add water to concrete during delivery or at Project site. Do not add water to fresh concrete after testing.

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 according to ACI 301 by mechanical vibrating equipment supplemented by hand spading, rodding, or tamping.

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. Screed paving surface with a straightedge and strike off.

153


H. Commence initial floating using bull floats or darbies to impart an open-textured and

uniform surface plane before excess moisture or bleedwater appears on the surface. Do not further disturb concrete surfaces before beginning finishing operations or spreading surface treatments.

I. Curbs and Gutters: Use design mixture for automatic machine placement. Produce curbs

and gutters to required cross section, lines, grades, finish, and jointing.

J. Slip-Form Paving: Use design mixture for automatic machine placement. Produce paving to required thickness, lines, grades, finish, and jointing.

1. Compact sub-base and prepare subgrade of sufficient width to prevent

displacement of slip-form paving machine during operations.

3.7 FLOAT FINISHING

A. General: Do not add water to concrete surfaces during finishing operations.

B. Float Finish: Begin the second floating operation when bleedwater sheen has disappeared and 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. Burlap Finish: Drag a seamless strip of damp burlap across float-finished concrete,

perpendicular to line of traffic, to provide a uniform, gritty texture. 2. Medium-to-Fine-Textured Broom Finish: Draw a soft-bristle broom across float-

finished concrete surface, perpendicular to line of traffic, to provide a uniform, fine- line texture.

3. Medium-to-Coarse-Textured Broom Finish: Provide a coarse finish by striating float- finished concrete surface 1/16 to 1/8 inch deep with a stiff-bristled broom, perpendicular to line of traffic.

3.8 CONCRETE PROTECTION AND CURING

A. General: Protect freshly placed concrete from premature drying and excessive cold or hot

temperatures.

B. Comply with ACI 306.1 for cold-weather protection.

C. Evaporation Retarder: Apply evaporation retarder to concrete surfaces if hot, dry, or windy conditions cause moisture loss approaching 0.2 lb/sq. ft. x h before and during finishing operations. Apply according to manufacturer's written instructions after placing, screeding, and bull floating or darbying concrete but before float finishing.

D. Begin curing after finishing concrete but not before free water has disappeared from

concrete surface.

E. Curing Methods: Cure concrete by moisture curing, moisture-retaining-cover curing, curing compound or a combination of these as follows: 1. Moisture Curing: Keep surfaces continuously moist for not less than seven days

with the following materials: 154


a. Water. b. Continuous water-fog spray. c. Absorptive cover, water saturated and kept continuously wet. Cover concrete

surfaces and edges with 12-inch lap over adjacent absorptive covers.

2. Moisture-Retaining-Cover Curing: Cover concrete surfaces with moisture-retaining cover, placed in widest practicable width, with sides and ends lapped at least 12 inches, and sealed by waterproof tape or adhesive. Immediately repair any holes or tears occurring during installation or curing period, using cover material and waterproof tape.

3. Curing Compound: Apply uniformly in continuous operation by power spray or roller according to manufacturer's written instructions. Recoat areas subjected to heavy rainfall within three hours after initial application. Maintain continuity of coating, and repair damage during curing period.

3.9 PAVING TOLERANCES

A. Comply with tolerances in ACI 117 and as follows:

1. Elevation: 3/4 inch. 2. Thickness: Plus 3/8 inch, minus 1/4 inch. 3. Surface: Gap below 10-feet-long; unleveled straightedge not to exceed 1/2 inch. 4. Alignment of Tie-Bar End Relative to Line Perpendicular to Paving Edge: 1/2 inch

per 12 inches of tie bar. 5. Lateral Alignment and Spacing of Dowels: 1 inch. 6. Vertical Alignment of Dowels: 1/4 inch. 7. Alignment of Dowel-Bar End Relative to Line Perpendicular to Paving Edge: 1/4

inch per 12 inches of dowel. 8. Joint Spacing: 3 inches. 9. Contraction Joint Depth: Plus 1/4 inch, no minus. 10. Joint Width: Plus 1/8 inch, no minus.

3.10 REPAIR AND PROTECTION

A. Remove and replace concrete paving that is broken, damaged, or defective or that does

not comply with requirements in this Section. Remove work in complete sections from joint to joint unless otherwise approved by Architect.

B. Protect concrete paving from damage. Exclude traffic from paving for at least 14 days

after placement. When construction traffic is permitted, maintain paving as clean as possible by removing surface stains and spillage of materials as they occur.

C. Maintain concrete paving free of stains, discoloration, dirt, and other foreign material.

Sweep paving not more than two days before date scheduled for final inspection. END OF SECTION 32 1313
