Add reinforcing fibers into concrete mixture in accordance with
manufacturer's instructions and ASTM C94.
| |

|
Add reinforcing fibers at a dosage rate of 4 pounds/cubic yard
of concrete directly into concrete mixer at beginning of batch cycle.
The reinforcing fibers shall be mixed at the concrete plant.
| |
C.
|
Allow a minimum of 4 minutes at mixing speed in concrete mixer
for full reinforcing fiber dispersion.
| |
D.
|
Concrete shall be as specified in Section NJDOT Class B.
| |
3.2
|
FIELD QUALITY CONTROL
| |
A.
|
Confirm uniform fiber dispersion throughout concrete in accordance
with manufacturer's instructions.
| |
B.
|
The concrete shall be intergrally dyed, "Smokey Blue" (Brickform
color 650) or approved equal. The dry intergral concrete color (i.e.
Powdered Color) shall be in compliance with ASTM C 979 and the application
rate shall be 12.5 lbs. per cubic yard. When the concrete has reached
the plastic stage desirable for imprinting, Brickform Liquid Release
or approved equal shall be used between the texture maps and concrete
to prevent sticking and concrete buildup. The location of the concrete
to be stamped is depicted on the plans. Apply in temperatures between
55 degrees and 80 degrees F. Do not trowel or mix colorless bond breaker
into plastic concrete surface. Press stamping mats in accordance with
manufacturer's instructions into concrete that has reached plastic
stage desirable for imprinting. Use the stamping mats to create patterns
in concrete as indicated on the drawings. Once the concrete is stamped,
the concrete shall be detailed to address all stamp imperfections
and repair and minor cracks caused by the mats.
| |
The integrally dyed concrete not stamped shall be scored at
the control joints creating a "Tooled Joint Look" using an ultra-early
entry concrete cutting saw and beveled blade. The 10'x10' pattern
shall be "picture framed" using 3/8' "v" profile blade by Soft-Cut
International, Inc. or approved equal. All control joints shall be
between 2 and 2.66 deep (D/4 and D/3).
| ||
The scored concrete shall have a finish texture of "extra small
veronica" texture as produced by Brickform or approved equal for the
concrete located on the outside of the pedestrian crosswalk (Main
and South sides of the crosswalks). The texture of scored concrete
located on the inside of the crosswalks shall be coquina produced
by Proline or approved equal. The concrete finished with the custom
stamp shall have a finish texture of "extra small blue stone" as produced
by Brickform or approved equal.
| ||
Upon completion of the stamp concrete detailing, the concrete
shall be cleaned and all efflorescence, oil, dirt, wax, sealers and
curing compounds shall be removed. The concrete shall be cleaned with
a pressure washer and soaps and detergents shall not be used for cleaning.
Dried residue on the surface will prevent the sealer from bonding.
Acid washing shall not be performed. Once the surface is cleaned and
dry for at least twenty-four (24) hours the concrete shall be sealed
with Brickform Gem Cure & Seal 1315-350 VOC or approved equal.
Gem Cure and Seal 1315-350 VOC shall be applied when the air temperature
is within 45 and 85 degrees F., apply with a pump sprayer uniformly
at a rate of 250-300 square feet per gallon, avoid heavy spray, puddling
and over saturation. A second coat shall be applied after the first
coat is tack free. Gem cure should be applied within 24-30 hours of
concrete stamping but it is imperative to wait until all the water
has evaporated from the concrete surface, even if it delays the curing
for a short time. Applying the cure and seal over integrally colored
concrete with excessive moisture at the surface may create discoloration,
splotchy areas, blushing and uneven color- if this occurs it shall
be the contractors responsibility to repair the concrete at no additional
cost. The second coat shall be applied a minimum of seventeen (17)
days after the first coat. If the sealer is applied seventy-two (72)
hours or greater after concrete stamping, the second coat of sealer
can be applied directly after the first coat has dried.
| ||
Prior to applying the sealer the Gem Cure & Seal the sealer
shall be modified by the addition of Brickform Traction Grip (second
coat only) and Brickform Matte-Magic (both the initial and second
coat). Add the contents of the Traction Grip to each five-gallon of
Brickform Gem Seal. The traction grip is an anti-slip micronized powder
that adds texture to sealers. The Brickform Matte-Magic is a liquid,
field added, flattening agent addition for the sealer. The original
topcoat gloss is reduced based on the amount of additive used. A satin
finish is desired, therefore, three to four 8 ounce units shall be
added to each 5 gallon of sealer. A concrete mock up shall be performed
to demonstrate that the concrete repair will match the color and finish
of the surrounding concrete surface. The actual amount will be determined
based upon the concrete mock up approved by the Borough.
| ||
Prior to sealing the concrete the concrete finish shall be enhanced
with dark grey highlites color hardener as produced by Brickform or
approved equal.
