to support
paving and imposed loads, free of frost, smooth and
properly compacted.
B. Verify gradients and elevations of base
are correct, and proper drainage has been
provided so that
water does not stand in the area to receive paving.
C.
Beginning of installation means acceptance of existing conditions.
3.2
PREPARATION
A. If no vapor retarding membrane is placed,
moisten base to minimize absorption of
water from fresh
concrete.
B. Notify Architect and testing laboratory, minimum
24 hours prior to commencement
of concreting operations.
3.3
FORMING
A. Construct and remove forms in accordance with ACI
347.
B Place and secure forms to correct location, dimension,
and profile. Adequately brace
to withstand loads applied
during concrete placement.
C. Assemble formwork to permit easy
stripping and dismantling without damaging
concrete.
D.
Place joint fillers vertical in position, in straight lines. Secure to
formwork during
concrete placement.

3.4
INSERTS AND ACCESSORIES
A. Make provisions for installation of
inserts, accessories, anchors, and sleeves.
******************************************************************************
Vapor
retarders are useful in exterior paving applications, especially where
slip resistance is
important (as in tennis courts) and where
surface condensation during certain climatic conditions
are
undesirable.
******************************************************************************
B.
[Place vapor retarder continuously over subgrade. Overlap joints a
minimum of 12
inches and seal with a joint tape of same
permeance as sheeting material.]
3.5 REINFORCEMENT
A.
Accurately place reinforcement in middle of slabs-on-grade.
B.
Discontinue every other bar of reinforcement at control and expansion
joints.
C. Place reinforcement to achieve slab and curb
alignment as detailed.
D. Steel shall be free of rust, mill
scale, dirt and oil.
E. Provide doweled joints at
interruptions of concrete with one end of dowel set in
capped
sleeve to allow longitudinal movement. Provide support at both ends of
dowels.
F.
Support reinforcing on bar chairs. Securely saddle tie at
intersections. Rigidly
secure in place to minimize
displacement during concrete pour.
3.6 JOINTS
A.
Intentional stoppage of concrete placing shall be at planned location
of either an
expansion joint or contraction joint.
B.
When stoppage occurs at an expansion joint, install joint assembly with
a bulkhead
of sufficient section drilled to accommodate
required dowels. Provide expansion
joints at maximum 40'-0"
[_______] o.c.e.w. in parking lots, 40'-0" [______] o.c. for
curbs
and maximum 20'-0" o.c.e.w. at pedestrian paving.
C. When
stoppage occurs at a contraction joint, install sheet metal joint
assembly of
sufficient section to prevent deflection, shaped
to concrete section. Drill bulkhead to
permit continuation of
longitudinal reinforcing steel through construction joint.
D.
Stoppage at Unintentional Location
1. Immediately upon
unintended stoppage of concrete placing, place available
concrete
to a line and install bulkhead perpendicular to surface of pavement and
at
required elevation. Place and finish concrete to this bulkhead. Remove
and
dispose of concrete remaining on subgrade ahead of
bulkhead.
2. When placing of concrete is resumed before
concrete has set to extent that
concrete will stand on removal
of bulkhead, new concrete shall be rodded with
the first;
otherwise, carefully preserve joint face.
3. Provide a joint
seal space at edges created by a construction joint of this type
shall
have a joint seal space as detailed on Drawings.
E. Provide
sawed contraction joints in vehicular paving and curbs spaced as
detailed on
Drawings, but in no case greater than 20 [____]
foot o.c. spacing.
4. Saw joints after completion of finishing
operations as soon as concrete has
hardened to extent
necessary to prevent revealing of joint or damage to adjacent
concrete
surfaces.
7
5. Saw joints same day that concrete is
placed except that sawing of joints in
concrete placed late in
day may be delayed until morning of following day.
6. In any
event, saw joints within 18 hours after placing concrete.
7.
Use a power-driven concrete saw made especially for sawing concrete and
maintain
in good operating condition.
8. Saw blades shall make a clean,
smooth cut, producing a groove 1/8" to 3/16"
wide and a depth
equal to 1/4 of slab thickness, minimum one inch (1") depth.
9.
Align joints in vehicular paving with joints in adjacent pedestrian
paving.
10. Cut joints through curbs at right angles to back
of curb.
F. Place joint filler between paving components and
building or other appurtenances.
[Recess top of filler 1 inch
for backing rod and sealant placement.]
G. Provide scored
joints in sidewalks and plazas to a depth of 1/4 the slab thickness, and
at
intervals as indicated, but in no case spaced greater than width of
walk.
3.7 PLACING CONCRETE
A. Place concrete in
accordance with ACI 301, 302, and 304. Deposit concrete so that
specified
slab thickness will be obtained after vibrating and finishing
operations.
Minimize handling to prevent segregation.
Consolidate concrete by suitable means
to prevent formation of
voids or honeycombs. Exercise care to prevent disturbance
of
forms and reinforcing and damage to vapor retarder. Place concrete to
lines and
levels shown, properly sloped to drain [into
adjacent] [yard areas] [drainage
structures].
B. Hot
Weather Placement: ACI 305.
C. Cold Weather Placement: ACI 306.
D.
Ensure reinforcement, inserts, embedded parts, and formed joints are
not disturbed
during concrete placement.
E. Place
concrete continuously between predetermined construction joints. Do not
break
or interrupt successive pours such that cold joints occur.
F.
While concrete is still in its plastic state, apply the tool/texture
pattern to the surface
of the concrete. Properly tamp tools
into the surface to achieve the required texture,
with
uniformity of pattern and depth of stamping. Utilize bond breaker to
keep tools
from sticking to fresh concrete.]
G. After
consolidating and screeding, float concrete to gradients indicated. Use
a
straight edge to level and test surface in longitudinal
direction to required grade.
Finish edges to provide a smooth
dense surface with 1/8" radius.
H. Place curing compound on
exposed concrete surfaces immediately after finishing.
Apply
in accordance with manufacturer's instructions.

THINK GREEN. We use
recycled concrete in lieu of gravel as aggregate in our
concrete. It doesn't cost us any extra; thus, it doesn't cost
you any extra. As far as structure, the recycled concrete is
just as strong as the gravel. We do what we can to save the
limited resources we have on earth.
