Section 02751 8

PART 3 - EXECUTION

3.1 PREPARATION

Before placing concrete, bring base surface to finish grade and elevations as shown. Moisten underlying material in advance of placing concrete to ensure a firm, moist condition at time concrete is placed. Do not permit equipment other than concrete delivery or paving equipment on prepared underlying material. In cold weather protect underlying material from frost. Do not use chemicals to eliminate frost. Maintain drainage ditches, gutters and side drains to drain the base during construction.

3.1.1 Base for Fixed Form Construction

Finish to the design profile. Test prepared surfaces with a template. Do not vary surface of base material more than 12 mm from indicated elevations.

3.1.2 Base for Slipform Construction Finish to the design profile. Do not vary surface of base material more than 12 mm from indicated elevations. Minimum width of sub-base shall be 600 mm greater on each side than the width of the paving to accommodate the slipform equipment tracks.

Grade and elevation control of the slip form paver shall be by string line.

3.2 FIXED FORMS

Set forms for full bearing on foundation for entire length and width and in alignment with edge of finished pavement. Support forms during entire operation of placing, compaction, and finishing so that forms will not deviate vertically more than 3 mm from required grade and elevations indicated. Maximum vertical deviation of top of any side form, including joints, shall not exceed 3 mm from a 3 meters straightedge, nor shall inside face vary more than 6 mm from a 3 meters straightedge. Provide stake sockets and interlocking devices that will prevent movement of the form.

3.3 JOINTS, REINFORCEMENT AND MOORING EYES

Place joints, welded wire fabric and mooring eyes in accordance with Section 02762, "Joints, Reinforcement, and Mooring Eyes in Concrete Pavements."

3.4 MEASURING AND MIXING

3.4.1 Site Mixing

ACI 325.9R.

3.4.2 Ready-Mixed Concrete

ASTM C 94/C 94M, except as modified herein. Begin mixing within 30 minutes after cement has been added to aggregates. Additional water may be added to bring slump within required limits as specified in Section 11.7 of ASTM C 94/C 94M, provided that specified water-cement ratio is not exceeded.

3.5 CONVEYING AND PLACING CONCRETE

3.5.1 Placing

ACI 325.9R, except as modified herein. Place concrete continuously at a uniform rate, with a minimum amount of segregation, without damage to the grade and without unscheduled stops except for equipment failure or other emergencies. If an emergency stop does occur within 3 meters of a previously placed expansion joint, remove concrete back to joint, repair any damage to grade, install

Section 02751 9 a construction joint and continue placing concrete only after cause of emergency stop has been corrected.

3.5.1.1 Cold Weather

ACI 306R. High-early-strength-concrete shall be maintained above freezing for a period greater than one-quarter of the period specified for Portland cement concrete or a minimum of 48 hours.

3.5.1.2 Hot Weather

ACI 305R.

3.5.2 Consolidation

ACI 309R, Chapter 11.

3.5.3 Protection Against Rain

ACI 325.9R, Chapter 10.4.

3.6 FINISHING

Start finishing operations immediately after consolidation. Use finishing machine, except that hand finishing may be used in emergencies and for concrete slabs that are of shapes or locations that are not accessible with a finishing machine. Finishing operations shall not displace coarse aggregate from surface and shall produce a surface of uniform texture true to grade and design profile. Excessive operation over an area, which results in an excess of mortar and water being brought to the surface, will not be permitted. Finish pavement surface on both sides of a joint to the same grade. Finish transverse joints from a securely supported transverse bridge.

3.6.1 Fixed Form Finishing

Maintain travel of machine on forms without vertical movement which will affect precision of concrete finish. Keep form tops clean by a device attached to the machine. Finish concrete flush with top of forms.

3.6.2 Slip-Form Finishing

Remove concrete slurry from vertical edges of slip-formed concrete using stiff brushes or other approved scrapers. Do not use concrete slurry to build up edges of concrete to compensate for edge slump. In locations where sloughing occurs, attach temporary forms to underlying material in the proper location and correct defective edges. Such procedures are to be used sparingly. Should excessive sloughing occur, halt operations until proper corrective adjustments have been made.

3.6.2.1 Edge Slump

Determine slump of edges with a 3.66 meter straightedge. Before the concrete hardens, correct edge slump of pave exceeding 6 mm at edge of pavement. The area affected by the downward movement of the concrete along the pavement edge shall be limited to not more than 450 mm from the edge.

3.6.3 Hand Finishing and Floating

As soon as placed and consolidated, strike off and screed concrete to required cross section.

If necessary, place and screed additional concrete and float until a satisfactory surface has been

Section 02751 10 produced. Advance floating operation not more than half the length of the float and then continue over new and previously floated surfaces. Hand finishing shall be limited to small irregular areas not accessible with finishing machine.

3.6.4 Surface Correction and Testing

After finishing is completed but while concrete is still plastic, use straightedges to eliminate minor irregularities and score marks. Use straightedges 3 meters in length and operated from sides of pavement and from bridges. Equip a straightedge operated from side of pavement with a handle 0.91 meters longer than one-half the width of pavement. Check surface for trueness with straightedge held in successive positions parallel and at right angles to center line of pavement, with whole area covered to detect variations. Advance straightedge along pavement in successive stages of not more than one-half the length of the straightedge.

Immediately fill depressions with freshly mixed concrete, strike off, consolidate, and refinish.

Strike off and refinish projections above required elevation. Continue straightedge testing and finishing until entire surface of concrete is free from observable departure from straightedge.

3.6.5 Texturing

ACI 325.6R. Before surface sheen has disappeared and before concrete becomes nonplastic, give the pavement surface a texture as specified in paragraph entitled "Surface Finish."

3.6.6 Surface Finish

3.6.6.1 Artificial Turf

Before concrete becomes non-plastic, finish surface by dragging a strip of clean, artificial turf 600 mm wider than pavement.

Select dimensions so that at least 600 mm of material in the direction of travel is in contact with…
