Obtain approval of scarified subgrade surfaces by City's representative prior to filling operations.

Scarify, dry, and compact soft and wet areas; remove and replace unsuitable subgrade materials with an approved fill material. Take corrective measures before placing fill materials.

Thoroughly scarify existing soil surface to a depth of 10" and as shown on the Soils Report and verify scarification with City's representative prior to placing fill material in mounded areas.

Spread approved fill material uniformly in layers not greater than 12" of loose thickness over entire fill zones of planting areas.

1. Lift thickness requirements may be modified by City’s representative to suit equipment and materials or other conditions when required to assure satisfactory compaction.

2. Place and compact each layer of fill before placing additional fill material. Repeat filling until proposed grade, profile or contour is attained.

3. Suspend fill operations when satisfactory results cannot be obtained because of environmental or other unsatisfactory site conditions. Do not use over-saturated fill materials. Do not place fill material on over-saturated subgrade surface.

4. Grade surfaces to assure positive drainage and to prevent ponding and pockets of surface drainage.

5. Protect finish graded areas from traffic and erosion. Keep free of trash and debris. Repair and reestablish grades in settled, eroded and damaged areas.

If, in the opinion of the City, the completed site grading does not reflect the intent of the Contract

Documents, an independent surveyor may be hired to verify the grades. If the grades are correct, the City will pay for the survey. If the grades are incorrect, the cost of the survey will be deducted from the Contract price.

3. Do not use mason sand or sand conforming to ASTM C 144 for the bedding sand.

Unit Pavers 02780 - 3

Note: Bedding sand durability is important for areas exposed to high traffic.

The engineer/architect is advised to evaluate the hardness of bedding sand with the following test method when the pavers and sand will be placed over concrete, or asphalt, and subject to major thoroughfare traffic (over 1.5 million ESALs):

One (1) 1.4 kg (3 lbs.) sample of bedding sand can be randomly sampled from the sand source. The sample is dried for 24 hours at 115° to 121° C. (240° to 250°

F.). Obtain three (3) sub-samples each weighing 0.2 kg (0.5 lbs.) by passing the main sample several times through a riffle box. Carry out a sieve analysis test on each sub-sample according to ASTM C 136. Re-mix each sub-sample and place in a nominal quart/liter capacity porcelain jar with two (2) 25 mm (1 inch) diameter steel ball bearings weighing 75 ±5 grams each. Rotate each jar at 50 rpm for six (6) hours. Repeat the sieve analysis. Record the individual and average sieve analysis. For each sample tested, the maximum increase in the percentages passing each sieve and the maximum individual percent passing should be as follows:

Sieve Size

No. 200 ( 0.075 mm)

No. 100 (0.150 mm)

Max. Increase

2.03 EDGE RESTRAINTS

A. Provide edge restraints installed around the perimeter of all interlocking concrete paving unit areas as follows:

1. Proposed poured-in-place concrete play curb or existing exposed aggregate concrete paving per plan.

PART III - EXECUTION

3.01 ACCEPTABLE INSTALLERS

A. See Submittals, Subsection1.03, heading D.

The elevations and surface tolerance of the base determine the final surface elevations of concrete pavers. The paver installation contractor cannot correct deficiencies in the base surface with additional bedding sand or by other means. Therefore, the surface elevations of the base should be checked and accepted by the General Contractor or designated party, with written certification to the paving subcontractor, prior to placing bedding sand and concrete pavers.

3.02 EXAMINATION

A. Acceptance of Site Verification of Conditions:

1. General Contractor shall inspect, accept and certify in writing to the paver installation subcontractor that site conditions meet specifications for the following items prior to installation of interlocking concrete pavers. a. Verify that subgrade preparation, compacted density and elevations b. c. conform to specified requirements.

Verify that geotextiles, if applicable, have been placed according to drawings and specifications.

Verify that base materials, thickness, compacted density, surface tolerances and elevations conform to specified requirements.

Unit Pavers 02780 - 5

d. e.

Manufacturer to provide written density test results for soil subgrade, base materials to the City representative, general contractor and paver installation subcontractor.

Verify location, type, and elevations of edge restraints, concrete collars around utility structures, and drainage holes and inlets.

2. Do not proceed with installation of bedding sand and interlocking concrete pavers until subgrade soil and base conditions are corrected by the General Contractor or designated subcontractor.

A.

3.03 PREPARATION

Verify base is clean and dry, certified by General Contractor as meeting material, installation and grade specifications.

B. Verify that base is ready to support sand, pavers and imposed loads.

3.04 INSTALLATION

A. Spread bedding sand evenly over the base course and screed to a nominal 1 in. (25 mm) thickness. Spread bedding sand evenly over the base course and screed rails, using the rails and/or edge restraints to produce a nominal 1 in. (25 mm) thickness, allowing for specified variation in the base surface.

1.

2.

Do not disturb screeded sand.

Screeded area shall not substantially exceed that which is covered by pavers in one day.

3. Do not use bedding sand to fill depressions in the base surface.

When initially placed on the bedding sand, manually installed pavers often touch each other, or their spacer bars if present. Joint widths and lines (bond lines) are straightened and aligned to specifications with rubber hammers and pry bars as paving proceeds.

B. Lay pavers in pattern(s) shown on drawings. Place units hand tight without using hammers. Make horizontal adjustments to placement of laid pavers with rubber hammers as required.

Contact manufacturer of interlocking concrete paver units for recommended joint widths.

C. Provide joints between pavers between [1/16 in. and 3/16 in. (2 and 5 mm)] wide. No more than 5% of the joints shall exceed [1/4 in. (6 mm)] wide to achieve straight bond lines.

D. Joint (bond) lines shall not deviate more than ±1/2 in. (±15 mm) over 50 ft. (15 m) from string lines.

E. Fill gaps at the edges of the paved area with cut pavers or edge units.

Unit Pavers 02780 - 6

F. Cut pavers to be placed along the edge with a masonry saw. Specify requirements for edge treatment in paragraph below.

G. Adjust bond pattern at pavement edges such that cutting of edge pavers is minimized. All cut pavers exposed to maintenance vehicle tires shall be no smaller than one-third of a whole paver. Cut pavers at edges as indicated on the drawings.

H. Keep skid steer and forklift equipment off newly laid pavers that have not received initial compaction and joint sand.

I. Use a low-amplitude plate compactor capable of at least minimum of 4,000 lbf (18 kN) at a frequency of 75 to 100 Hz to vibrate the pavers into the sand. Remove any cracked or damaged pavers and replace with new units.

J. Simultaneously spread, sweep and compact dry joint sand into joints continuously until full. This will require at least 4 to 6 passes with a plate compactor. Do not compact within 6 ft (2 m) of unrestrained edges of paving units.

K. All work within 6 ft. (2 m) of the laying face must shall be left fully compacted with sandfilled joints at the end of each day or compacted upon acceptance of the work. Cover the laying face or any incomplete areas with plastic sheets overnight if not closed with cut and compacted pavers with joint sand to prevent exposed bedding sand from becoming saturated from rainfall.

L. Remove excess sand from surface when installation is complete. Excess joint sand can remain on surface of pavers to aid in protecting their surface especially when additional construction occurs after their installation. If this is the case, delete the article above and use the article below. Designate person responsible for directing timing of removal of excess joint sand.

M. Allow excess joint sand to remain on surface to protect pavers from damage from other trades. Remove excess sand when directed by the City representative.

N. Surface shall be broom clean after removal of excess joint sand.

3.05 FIELD QUALITY CONTROL

Surface tolerances on flat slopes should be measured with a rigid straightedge. Tolerances on complex contoured slopes should be measured with a flexible straightedge capable of conforming to the complex curves on the pavement surface.

A. The final surface tolerance from grade elevations shall not deviate more than ±3/8 in.

(±10 mm) under a 10 ft (3 m) straightedge.

B. Check final surface elevations for conformance to drawings.

Note: For installations on a compacted aggregate base and soil subgrade, the top surface of the pavers may be 1/8 to 1/4 in. (3 to 6 mm) above the final elevations after compaction.

This helps compensate for possible minor settling normal to pavements.

Unit Pavers 02780 - 7

C. The surface elevation of pavers shall be 1/8 in. to 1/4 in. (3 to 6 mm) above adjacent drainage inlets, concrete collars or channels.

D. Lippage: No greater than 1/8 in. (3 mm) difference in height between adjacent pavers.

Cleaning and sealing may be required for some applications. See ICPI Tech Spec 5,

Cleaning and Sealing Interlocking Concrete Pavements for guidance on when to clean and seal the paver surface, and when to stabilize joint sand. Delete article below if cleaners, sealers, and or joint sand stabilizers are not applied.

3.06 JOINT SAND STABILIZATION

A. Apply joint sand stabilization materials between] concrete pavers in accordance with the manufacturer’s written recommendations.

3.07 PROTECTION

A. After work in this section is complete, the General Contractor shall be responsible for protecting work from damage due to subsequent construction activity on the site.
