Additional water may be added, provided that both the specified maximum slump and water-cement ratio are not exceeded. When additional water is added, an additional 30 revolutions of the mixer at maximum speed is required. Dissolve admixtures in the mixing water and mix in the drum to uniformly distribute the mixture throughout the batch.

10.1 Surface Preparation

Before placing the concrete, thoroughly clean the vertical exposed faces of the existing slabs to remove contaminates. Use a wire brush or other approved methods to remove contaminates. Remove existing sealant from exposed concrete faces.

10.2 Preparing Base

Remove debris and standing water from the base. Thoroughly compact loose base material by tamping before placing concrete. Reinforcement shall be placed as directed.

New concrete slabs shall be placed upon compacted soil free from ice, frost or water.

Base material shall be compacted to at less 95% of laboratory maximum density.

11. CONCRETE PLACEMENT: Deliver concrete from mixer to forms continuously until approved unit of operation is completed. Provide scaffolding, ramps and walkways so that personnel and equipment are not supported by in-place reinforcement. Placing will not be permitted when sun, heat, wind, or limitations of facilities furnished by the Contractor prevent proper consolidation, finishing and curing. Deposit concrete as close as possible to its final position in the forms. When a vertical drop greater than 8 feet is authorized, provide equipment to prevent segregation. Regulate depositing of concrete so that it will be consolidated in horizontal layers not more than 12 inches thick. Place slabs in one layer. Screed concrete to provide levels and profiles indicated.

12. VIBRATION: Work in accordance with ACI 301. Furnish a spare working vibrator on the job site whenever concrete is placed. Consolidate concrete slabs greater than 4 inches in depth with high frequency mechanical vibrating equipment supplemented by hand spading and tamping. Consolidate concrete slabs 4 inches or less in depth by wood tampers, spading and settling with heavy leveling straightedge. Use vibrators adequate in effectiveness and number to properly consolidate the concrete. Insert and withdraw vibrators approximately 18 inches apart. Penetrate the previously placed lift with the vibrator when more than one lift is required. External vibrators shall be used on the exterior surface of a form when internal vibrators do not provide adequate consolidation of the concrete.

13. CURING shall start as soon as free water has disappeared from concrete surfaces after placing and finishing. Curing materials shall be applied and maintained so as to protect the concrete from moisture loss for 7 days. Curing shall be accomplished by impervious sheet or membrane-forming curing compound. Concrete surfaces shall be thoroughly wetted before covering with impervious-sheet materials. Membrane-forming curing compound shall be applied with mechanical spraying equipment at a coverage rate of not more than 300 square feet per gallon. Surfaces of compound damaged during curing shall be resprayed. Follow requirements of ACI 305.1 for Hot Weather concreting and ACI 306.1 for Cold Weather concreting.

Unsound concrete, voids over 1/2 inch in diameter, and tie-rod and bolt holes shall be cut back to solid concrete, reamed, brush-coated with cement grout, and filled solid with a stiff portland-cement-sand mortar mix. Patchwork shall finish flush with adjoining concrete surfaces and, where exposed, shall match adjoining surfaces in texture and color.

Patchwork shall be cured for 72 hours. White portland cement shall be used as needed to attain color match.

15.2 Unformed Surfaces: Surfaces shall be finished to a true plane with no deviation exceeding 5/16 inch when tested with a 10-foot straightedge. Surfaces shall be pitched to drain. Surfaces shall be screeded and floated to the required finish level with no coarse aggregate visible before finishing as specified below.

15.3 Nonslip Finish: The concrete shall receive a nonslip finish so indicated by brooming with a fiber-bristle brush in a direction transverse to that of main traffic. Do not use a burlap drag on fiber reinforced concrete. Finish concrete in accordance with ACI 301 Section 5 for a broom finish.

15.4 Expansion Joints: Form expansion joints where required and specified. Install around any structure and features that project through or onto the pavement, using preformed joint filler of the type, thickness, and width indicated. Expansion joints shall extend the full slab depth. Finish the edges of the concrete at the joint face with an edger with a radius of 0.125 inch. Install the joint filler strip to form a recess at the pavement surface to be filled with joint sealant.

15.5 New Sawed Joints in Concrete: Construct sawed joints by sawing a groove in the concrete with a 0.125 inch blade to the indicated depth. The time of initial sawing will vary depending on existing and anticipated weather conditions and will be such as to prevent uncontrolled cracking of the pavement. Commence sawing of the joints as soon as the concrete has hardened sufficiently to permit cutting the concrete without chipping, spalling, or tearing. Saw the joints at the required spacing consecutively in the sequence of the concrete placement. Discontinue sawing at a given joint location when a crack develops ahead of the saw cut. Immediately after the joint is sawed, thoroughly flush the saw cut and adjacent concrete surface with water until all waste from sawing is removed from the joint. Respray the surface with curing compound as soon as free water disappears. The top of the joint opening and the joint groove at the exposed edges shall be tightly sealed with cord or backer rod before the concrete in the region of the joint is resprayed with curing compound.

15.5.1 Contraction Joints: Transverse and longitudinal contraction joints shall be the weakened-plane or dummy type. Construct longitudinal contraction joints by sawing a groove in the hardened concrete with a power-driven saw. Construct transverse contraction joint in conformance with the requirements for the sawed joint.

15.5.2 Transverse Construction Joints: Transverse contraction joints shall be installed at the end of each day’s placing operations and at any point within a paving lane when placement is interrupted for 30 minutes or longer. The transverse contraction joints shall be constructed by utilizing headers or by paving through the joint, then full-depth sawcutting the excess concrete. Pavement shall be constructed with the paver as close to the header as possible. Transverse construction joints installed at a planned transverse joint shall be constructed as shown.

16. TESTING: Contractor is responsible for testing concrete to determine concrete strength. Each test shall comprise of taking three (3) test cylinders to determine 7, 14 and 28-day strengths of the new concrete. A minimum of one test each day that concrete is placed is required and a minimum of one test for each 50 cubic yards of concrete placed in one day is required.

17. REMOVAL OF EXISTING CONCRETE APPROACH: Contractor may be required to remove existing concrete approach. If required, contractor shall remove existing slab complete to size as directed. Saw cut existing slab for removal and smooth tie-in between new and existing surfaces. Existing concrete material shall be removed from bridge site and disposed of off government property. Excavate, backfill and compact area as required to install new slab.

18. SEALING EXISTING CONCRETE BRIDGE DECK JOINTS: A scoping will be held on each job site, between the contractor and government, and an agreement will be made on the slabs, joints, etc. to be repair or replaced.
