3. For paving greater than eight feet in width, locate joints such that he maximum jointspacing does not exceed 36 times the slab thickness in inches.a. As an example, a four inch (4") thick pavement, joints would have joints located not to

exceed twelve feet (12').4. All panels should be square or nearly so with the length never to exceed 1.5 times the

width.5. Sawed Joints: Saw cut joints shall be made within 4 hours of concrete placement;

excessive spalling or ravelling of concrete surface at saw cuts shall be reason forreplacement of concrete as outlined herein at no additional cost.a. Employ sufficient number of saws and skilled workers to complete cutting saw

joints before shrinkage produces cracking.b. Saw cut to minimum width of 1/8 inch; width shall be consistent throughout joint.c. Start cutting sawed joints as soon as concrete has hardened sufficiently to prevent

ravelling or dislodging of aggregates.d. Saw cut joints shall be made within 4 hours of concrete placement and after

completing finishing of slab in that joint location.e. Remove all saw debris, either loose or compacted, from slab surface and joints

prior to curing installation.

3.10 FINISHING

A. General:1. Do not add water to any slab surface during finishing operations.2. Do not add cement to any slab surface during finishing operations.3. Perform no finishing operations while water is present on slab surface.

B. After striking-off and consolidating concrete, smooth surface by screeding and floating. Usehand methods only where mechanical floating is not possible. Adjust floating to compact surfaceand produce uniform texture.

C. After floating, test surface for trueness with a 10-ft. straightedge. Distribute concrete as requiredto remove surface irregularities, and refloat repaired areas to provide a continuous smoothfinish.

D. Sidewalk. landing, dumpster pad and accessible parking spaces paving: Light broom, textureperpendicular to direction of travel with troweled and radiused edge 1/4 inch radius.1. Where new portland cement concrete paving abutts existing concrete paving, match

existing concrete paving finishing.


2. Remove all tool and trowel marks.

E. Curbs: Light broom, texture parallel to pavement direction.

F. Curing General:1. Cure concrete in accordance with ACI 301 and ACI 308R unless noted otherwise.2. Start curing as soon as concrete surface shall not be damaged by curing operations.3. Continuously cure concrete for at least 7 consecutive days.4. During curing period, do not allow any part of the concrete to become dry.

G. Place curing compound on exposed concrete surfaces immediately after finishing. Apply inaccordance with manufacturer's instructions.1. Do not use liquid curing compound on surface against which additional concrete, other

finishing materials, or coatings are to be bonded if the bond shall be affected by the curingcompound.

2. Immediately recoat surfaces subjected to rainfall within 3 hours after compound has beenapplied or surfaces damaged by subsequent construction operations within the curingperiod.

3. Barricade concrete surfaces immediately after application of curing compound.4. Do not allow traffic on concrete surfaces sooner than 3 days after placement or as

recommended by curing compound manufacturer; comply with the more stringentrequirement.

H. Concrete Sealer: Apply sealer uniformly to all new portland cement concrete paving incontinuous operation according to manufacturer's written instructions.

3.11 JOINT SEALING

A. Pennsylvania Department of Transportation, Publication 408, Section 501 Reinforced or PlainCement Concrete Pavements.

3.12 TOLERANCES

A. Maximum Variation of Surface Flatness: 1/4 inch in 10 ft.

B. Maximum Variation From True Position: 1/4 inch.

3.13 BACKFILLING

A. After curing, debris shall be removed and the areas adjoining shall be backfilled, graded andcompacted to conform to the surrounding area in accordance with the lines and gradesindicated.


A. Compressive Strength Tests: ASTM C39/C39M; for each test, mold and cure three concretetest cylinders. Obtain test samples for every 100 cu yd or less of each class of concrete placed.1. Take one additional test cylinder during cold weather concreting, cured on job site under

same conditions as concrete it represents.2. Perform one slump test for each set of test cylinders taken.


B. Maintain records of placed concrete items. Record date, location of pour, quantity, airtemperature, and test samples taken.

3.15 PROTECTION AND REPLACEMENT

A. Immediately after placement, protect pavement from premature drying, excessive hot or coldtemperatures, and mechanical injury.

B. Remove and replace concrete paving that is broken, damaged, or defective, or does not meetthe requirements of this Section. Defects include color and texture irregularities, crazing andcracks in excess of 0.01 inch wide or that penetrate to the reinforcement or completely throughnonreinforced sections regardless of width, spalls, air bubbles, honeycomb, rock pockets, finsand other projections on the surface, and stains and other discolorations that cannot beremoved by cleaning.1. Area for removal and replacement shall be defined by a perimeter determined by

isolation, contraction, and construction joints that completely contain within theirprescribed border the break, damage, defect or otherwise unacceptable concrete paving. In no case shall additional joints, saw cuts, etc. be permitted without the expresspermission.a. Remove defective areas with clean, square cuts.b. Mix replacement concrete of same materials to provide concrete of same type or

class as original concrete. Prepare, place, reinforce, consolidate, and finish tomatch adjacent finished concrete. Cure and seal in same manner as adjacentconcrete.

c. Where possible, portions of the work cast or set integrally may be salvaged forre-use provided that each item be re-installed according to original ContractDocuments requirements.

2. In the case of ramps and stairs, the entire run incorporating all intermediate landings ofthe ramp and/or stair shall be removed and replaced.a. Remove defective areas with clean, square cuts.b. Mix replacement concrete of same materials to provide concrete of same type or

class as original concrete. Place, compact, and finish to match adjacent finishedconcrete. Cure in same manner as adjacent concrete.

c. Where possible, portions of the work cast or set integrally may be salvaged forre-use provided that each item be re-installed according to original ContractDocuments requirements.

C. Drill test cores where directed when necessary to determine magnitude of cracks or defectiveareas. Fill drilled core holes in satisfactory pavement areas with portland cement concretebonded to paving with epoxy adhesive.

D. Do not permit pedestrian or vehicular traffic over pavement for 28 days minimum after finishing.1. When construction traffic is permitted, maintain paving as clean as possible by removing

surface stains and spillage of materials as they occur.2. Provide access ramps along exposed concrete edges to prevent equipment and

machinery from impacting edges; barricade all other exposed edges to machinery andvehicular traffic which may damage edges.

E. Maintain concrete paving free of stains, discoloration, dirt, and other foreign material. Sweepconcrete paving not more than 2 days prior to date scheduled for Substantial Completioninspections.
