In combined curb and gutter and valley gutter sections, locate expansion joints at the tangent point of all curves, each side of inlets, and at intervals of not more than 250 feet in straight runs. Expansion joints shall be cut to full size and shape of the cross section of the curb and gutter less one-half inch from the finished surface thereof. The edges of the blocks against the joint shall be finished with an edging tool and the joint raked clean of concrete.

I nstallation of joint fillers and sealants is specified in Division 7 Section "Joint Sealants."

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

CONCRETE PLACEMENT

Inspection: Before placing concrete, inspect and complete formwork installation, reinforcing steel, and items to be embedded or cast in. Notify other trades to permit installation of their work.

Remove snow, ice, or frost from subbase surface and reinforcing before placing concrete. Do not place concrete on surfaces that are frozen.

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.

Comply with requirements and with ACI 304R for measuring, mixing, transporting, and placing concrete.

Deposit and spread concrete in a continuous operation between transverse joints. Do not push or drag oncrete into place or use vibrators to move concrete into place. c

When concrete placing is interrupted for more than 1/2 hour, place a construction joint.

Use a bonding agent at locations where fresh concrete is placed against hardened or partially hardened concrete surfaces.

Consolidate concrete by mechanical vibrating equipment supplemented by hand-spading, rodding, or tamping. Use equipment and procedures to consolidate concrete complying with ACI 309R.

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 reinforcing, dowels, and joint devices.

Screed paved surfaces with a straightedge and strike off. Use bull floats or darbies to form a smooth surface plane before excess moisture or bleed water appears on the surface. Do not further disturb

PORTLAND CEMENT CONCRETE PAVING 02520 - 8

concrete surfaces prior to beginning finishing operations.

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 ot acceptable, remove and replace with formed concrete. n Cold-Weather Placement: Comply with provisions of ACI 306R and as follows. Protect concrete work from physical damage or reduced strength that could be caused by frost, freezing actions, or low temperatures.

When air temperature has fallen to or is expected to fall below 40 deg F (4 deg C), uniformly heat water and aggregates before mixing to obtain a concrete mixture temperature of not less than 50 deg F (10 deg C) and not more than 80 deg F (27 deg C) at point of placement.

Do not use frozen materials or materials containing ice or snow.

Do not use calcium chloride, salt, or other materials containing antifreeze agents or chemical accelerators unless otherwise accepted in mix designs.

Hot-Weather Placement: Place concrete complying with ACI 305R and as specified when hot weather conditions exist.

Cool ingredients before mixing to maintain concrete temperature at time of placement to below 90 deg F (32 deg C). Mixing water may be chilled or chopped ice may be used to control temperature, provided water equivalent of ice is calculated to total amount of mixing water. Using liquid nitrogen to cool concrete is Contractor's option.

Cover reinforcing steel with water-soaked burlap if it becomes too hot, so that steel temperature will not exceed the ambient air temperature immediately before embedding in concrete.

Fog spray forms, reinforcing steel, and subgrade just before placing concrete. Keep subgrade moisture uniform without standing water, soft spots, or dry areas.

CONCRETE FINISHING

Float Finish: Begin floating 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 within a tolerance of 1/4 inch in 10 feet as determined by a 10-foot-long straightedge placed anywhere on the surface in any direction. Cut s and fill low spots. Refloat surface immediately to a uniform granular texture. down high spot Medium Textured Broom Finish: Draw a bristle broom across concrete surface perpendicular to line of traffic to provide a uniform fine line texture finish. Repeat operation if required to provide a texture acceptable to Architect.

tool.

Repeat tooling of edges and joints after applying surface finishes. Eliminate tool marks on concrete urfaces. s

CONCRETE PROTECTION AND CURING

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

Comply with the recommendations of ACI 306R for cold weather protection and ACI 305R for hot weather protection during curing.

Evaporation Control: In hot, dry, and windy weather, protect concrete from rapid moisture loss before and during finishing operations with an evaporation-control material. Apply according to manufacturer's instructions after screeding and bull floating, but before floating.

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

Curing Methods: Cure concrete by moisture curing, moisture-retaining-cover curing, curing compound, or a combination of these as follows:

Moisture Curing: Keep surfaces continuously moist for not less than 7 days with the following materials:

Water.

Continuous water-fog spray.

Absorptive cover, water saturated, and kept continuously wet. Cover concrete surfaces and edges with a 12-inch lap over adjacent absorptive covers.

Moisture-Retaining-Cover Curing: Cover concrete surfaces with moisture-retaining cover for curing concrete, 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 during curing period using cover material and waterproof tape.

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

TRAFFIC PAINT

Traffic Paint: Apply traffic paint for striping and other markings with mechanical equipment to produce uniform straight edges. Apply at manufacturer's recommended rates to provide a 15-mil minimum wet film thickness.

F IELD QUALITY CONTROL TESTING

Employ a qualified independent testing and inspection agency to sample materials, perform tests, and submit test reports during concrete placement as specified in Section 03300.

REPAIRS AND PROTECTION

PORTLAND CEMENT CONCRETE PAVING 02520 - 10

Remove and replace concrete paving that is broken, damaged, or defective, or does not meet the requirements of this Section.

Drill test cores where directed by Contracting Officer when necessary to determine magnitude of cracks or defective areas. Fill drilled core holes in satisfactory pavement areas with portland cement concrete bonded to paving with epoxy adhesive.

Protect concrete 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.

Maintain concrete paving free of stains, discoloration, dirt, and other foreign material. Sweep concrete paving prior to date scheduled for Substantial Completion.
