03300 for concrete materials, admixtures, bonding materials, curing materials, and others as required.

C. Joint Fillers: Resilient premolded bituminous impregnated

fiberboard units complying with ASTM D 1751 FS HH-F-341, Type II, Class A; or AASHTO M 153, Type I.

D. Joint Sealers: Non-priming, pourable, self-leveling polyurethane.

Acceptable sealants are Sonneborn "Sonolastic Paving Joint Seal- ant" Sonneborn "Sonomeric CT 1 Sealant", Sonneborn "Sonomeric CT 2 Sealant", Mameco "Vulken 45", or Woodmont Products "Chem-Caulk".

E. Reinforcing Bars: Deformed steel bars, ASTM, A 615, Grade 40.

2.02 MIX DESIGN AND TESTING

A. Concrete mix design and testing shall comply with requirements of

applicable Section 03300.

B. Design mix to produce normal weight concrete consisting of Portland cement, aggregate, water-reducing admixture, air-entraining admixture, and water to produce the following properties:

1. Compressive Strength: 32 MPA, minimum at 28 days, unless

otherwise indicated on the Drawings on specifications.

2. Slump Range: 50 mm - 125 mm at time of placement.

3. Air Entrainment: 5% to 8%.



A. Proof-roll prepared base material surface to check for unstable

areas. The paving work shall begin after any unsuitable areas have been corrected and are ready to receive paving. Compaction testing for the base material shall be completed prior to the placement of

the paving.

B. Surface Preparation: Remove loose material from compacted base material surface to produce a firm, smooth surface immediately before placing concrete.

3.02 INSTALLATION

A. Form Construction

1. Set forms to required grades and lines, rigidly braced and

secured.

2. Install sufficient quantity of forms to allow continuance of work and so that forms remain in place a minimum of 24 hours after concrete placement.

3. Check completed formwork for grade and alignment to

following tolerances:

- Top of forms not more than 3 mm in 3.0 m. - Vertical face on longitudinal axis, not more than 6 mm

in 3.0 m.

4. Clean forms after each use, and coat with form release agent as often as required to ensure separation from concrete without damage.

B. Concrete Placement

1. Comply with applicable requirements of Section 03300.

2. Do not place concrete until base material and forms have

been checked for line and grade. Moisten base material if

required to provide uniform dampened condition at time concrete is placed. Concrete shall not be placed around manholes or other structures until they are at the required

finish elevation and alignment.

3. Place concrete using methods which prevent segregation of mix. Consolidate concrete along face of forms and adjacent to transverse joints with internal vibrator. Keep vibrator

away from joint assemblies, reinforcement, or side forms. Consolidate with care to prevent dislocation of dowels, and joint devices.


4. Deposit and spread concrete in continuous operation between

transverse joints, as far as possible. If interrupted for more than 1/2 hour, place construction joint. Automatic

machine may be used for curb and gutter placement at Contractor's option. Machine placement must produce curbs and gutters to required cross section, lines, grades,

finish, and jointing as specified for formed concrete. When the machine placement option is utilized, the granular base must be graded to within 30mm of the underside of curb prior

to curb installation commencement. If results are not acceptable, remove and replace with formed concrete as specified.

C. Joint Construction

1. Contraction Joints: Concrete curb, concrete gutter or

concrete curb and gutter, where specified on the plans,

shall be constructed in uniform sections of the length specified on the plans. The joints between sections shall be

formed either by steel templates 3.0 mm in thickness, of a length equal to the width of the gutter and/or curb, and with a depth which will penetrate at least 50 mm below the

surface of the curb and/or gutter; or with 19 mm thick preformed expansion joint filler cut to the exact cross section of the curb and/or gutter; or by sawing to a depth

of at least 50 mm while the concrete is between 4 to 24 hours old. If steel templates are used, they shall be left in place until the concrete has set sufficiently to hold its

shape, but shall be removed while the forms are still in place.

2. Longitudinal Construction Joints: Concrete curb, concrete

gutter or combination concrete curb and gutter, where

specified on the plans, shall be tied to concrete pavement with 15 m round deformed reinforcement bars of the length

and spacing shown on the plans.

3. Transverse Expansion Joints: Transverse expansion joint in

curb, curb and gutter, gutter or sidewalk shall have the filler cut to the exact cross section of the curb, curb and

gutter, gutter or sidewalk. The joints shall be similar to the type of expansion joint used in the adjacent pavement.

D. Joint Fillers: Extend joint fillers full-width and depth of

joint, and not less than 13 mm or more than 25 mm below finished

surface where joint sealer is indicated. Furnish joint fillers in one-piece lengths for full width being placed, wherever possible. Where more than one length is required, lace or clip joint filler

sections together.

E. Joint Sealants: All joints shall be sealed with approved exterior pavement joint sealants and shall be installed per manufacturer's

recommendations. 3.03 CONCRETE FINISHING

A. After striking off and consolidating concrete, smooth surface by

screeding and floating. Adjust floating to compact surface and produce uniform texture. After floating, test surface for trueness with 3.0 m straightedge. Distribute concrete as required to remove

surface irregularities, and refloat repaired areas to provide continuous smooth finish.


B. Work edges of sidewalks, gutters, back top edge of integral curb,

and formed joints with an edging tool, and round to 13 mm radius. Eliminate tool marks on concrete surface. After completion of floating and troweling when excess moisture or surface sheen has

disappeared, complete surface finishing, as follows:

1. Inclined Slab Surfaces: Provide coarse, nonslip finish by scoring surface with stiff-bristled broom perpendicular to

line of traffic.

2. Curbs, gutters, and walks: Broom finish by drawing fine-hair broom across surface perpendicular to line of traffic. Repeat operation as necessary to produce a fine line

texture.

C. Do not remove forms for 24 hours after concrete has been placed. After form removal, clean ends of joints and point up any minor honeycombed areas. Remove and replace areas or sections with major defects, as directed.

D. Protect and cure finished concrete paving using acceptable

moist-curing methods, more particularly described in the "water-curing" section of ACI 308.

3.04 BACKFILL

After the concrete has set sufficiently, the spaces in front and back of the curb and gutter or sidewalk shall be refilled to the required

elevation with suitable material which shall be compacted until firm and solid and neatly graded.

3.05 CLEANING AND ADJUSTING

A. Sweep concrete pavement and wash free of stains, discolorations,

dirt, and other foreign material just prior to final inspection.

B. Protect concrete from damage until acceptance of work. Exclude

traffic from pavement for at least 14 days after placement. When construction traffic is permitted, maintain pavement as clean as

possible by removing surface stains and spillage of materials. 3.06 TRANSPORTATION

EXECUTION

3.01 PREPARATION

A. Proof-roll prepared base material surface to check for unstable areas. The

paving Work shall begin after any unsuitable areas have been corrected and

02525 - 3 of 5


are ready to receive paving. Compaction testing for the base material

shall be completed prior to the placement of the paving.

B. Surface preparation: Remove loose material from compacted base material

surface to produce a firm, smooth surface immediately before placing

concrete.

C. Due to the phasing of parking lot construction, a shoulder will be

constructed at the limit of the Phase I parking and roadway areas

adjoining future phases as shown on the Drawings. No curbs are to be

installed where shoulders are constructed. Shoulders will be an extension

of the granular road base materials beyond the limit of the paved surface

with increased depths as required adjacent to the asphalt edge and will

include all items shown on detail Drawings.

3.02 INSTALLATION

A. Form construction:

1. Set forms to the required grades and lines, rigidly braced and

secured.

2. Install sufficient quantity of forms to allow continuance of Work

and so that forms remain in place a minimum of 24 hours after

concrete placement.

3. Check completed formwork for grade and alignment to following

tolerances:

a) Top of forms not more than 3 mm in 3.0 m. b) Vertical face on longitudinal axis, not more than 6 mm in

3.0 m. 4. Clean forms after each use, and coat with form release agent as

often as required to ensure separation from concrete without damage.

B. Concrete placement:

1. Do not place concrete until base material and forms have been

checked for line and grade. Moisten base material if required to

Provide uniform dampened condition at time concrete is placed.

Concrete shall not be placed around manholes or other structures

until they are at the required finish elevation and alignment.

2. Place concrete using methods which prevent segregation of mix. Consolidate concrete along face of forms and adjacent to transverse joints with internal vibrator. Keep vibrator away from joint assemblies, reinforcement, or side forms. Consolidate with care to prevent dislocation of dowels, and joint devices.

3. Deposit and spread concrete in continuous operation between transverse joints, as far as possible. If interrupted for more than 1/2 hour, place construction joint. Automatic machine may be used for curb and gutter placement at Contractor's option. Machine placement must produce curbs and gutters to required cross section, lines, grades, finish, and jointing as specified for formed concrete. When the machine placement option is utilized, the granular base must be graded to within 30mm of the underside of curb prior to curb installation commencement. If results are not acceptable, remove and replace with formed concrete as specified.

02525 - 4 of 5


C. Joint construction:

1. Contraction joints: Concrete curb, concrete gutter or concrete

curb and gutter, where specified on the plans, shall be

constructed in uniform sections of the length specified on the

plans. The joints between sections shall be formed either by steel

templates 3.0 mm in thickness, of a length equal to the width of

the gutter and/or curb, and with a depth which will penetrate at

least 50 mm below the surface of the curb and/or gutter; or with

19 mm thick preformed expansion joint filler cut to the exact

cross section of the curb and/or gutter; or by sawing to a depth

of at least 50 mm while the concrete is between 4 to 24 hours old.

If steel templates are used, they shall be left in place until

the concrete has set sufficiently to hold its shape, but shall be

removed while the forms are still in place.

2. Longitudinal construction joints: Concrete curb, concrete gutter

or combination concrete curb and gutter, where specified on the

plans, shall be tied to concrete pavement with 15 mm round

deformed reinforcement bars of the length and spacing shown on the

plans.

3. Transverse expansion joints: Transverse expansion joint in curb,

curb and gutter, gutter or sidewalk shall have the filler cut to

the exact cross section of the curb, curb and gutter, gutter or

sidewalk. The joints shall be similar to the type of expansion

joint used in the adjacent pavement.

D. Joint fillers: Extend joint fillers full-width and depth of joint, and

not less than 13 mm or more than 25 mm below finished surface where joint

sealer is indicated. Furnish joint fillers in one-piece lengths for full

width being placed, wherever possible. Where more than one length is

required, lace or clip joint filler sections together.

E. Joint sealants: All joints shall be sealed with approved exterior pavement

joint sealants and shall be installed per manufacturer's recommendations.

3.03 CONCRETE FINISHING

A. After striking off and consolidating concrete, smooth surface by screeding

and floating. Adjust floating to compact surface and produce uniform

texture. After floating, test surface for trueness with 3.0 m

straightedge. Distribute concrete as required to remove surface

irregularities, and refloat repaired areas to Provide continuous smooth

finish.

B. Work edges of sidewalks, gutters, back top edge of integral curb, and

formed joints with an edging tool, and round to 13 mm radius. Eliminate

tool marks on concrete surface. After completion of floating and

trowelling when excess moisture or surface sheen has disappeared, complete

surface finishing, as follows:

1. Inclined slab surfaces: Provide coarse, nonslip finish by scoring

surface with stiff-bristled broom perpendicular to line of

traffic.

02525 - 5 of 5


2. Curbs, gutters, and walks: Broom finish by drawing fine-hair broom

across surface perpendicular to line of traffic. Repeat operation

as necessary to produce a fine line texture.

C. Do not remove forms for 24 hours after concrete has been placed. After

form removal, clean ends of joints and point up any minor honeycombed

areas. Remove and replace areas or sections with major defects, as

directed.

D. Protect and cure finished concrete paving using acceptable moist-curing

methods, more particularly described in the "water-curing" section of ACI

308 or approved curing compound.

3.04 BACKFILL
