STREETS AND PAVING
1. SCOPE OF WORK
A. The work required under this section includes all
concrete and bituminous paving and related items
necessary to complete the work indicated on drawings
and described in the specifications, including but not
limited to:
All streets, parking areas in contract limits
Curbs and gutters.
Sidewalks and concrete slabs, exterior steps.
2. MATERIALS
A. Concrete - Concrete shall be ready-mixed concrete
and shall be a mix of proportioned fine and coarse
aggregates with Portland cement and water.
Minimum cement content shall be 6 bags per cubic
yard of concrete and maximum water content shall
be 5.5 U.S. gallons per sack of cement, including
moisture in the aggregate. Slump for normal weight
concrete shall be a maximum of 4 inches and a
minimum of 2 inches. The slump of machine place
concrete shall be no less than 1-1/4 inches nor
more than 3 inches. Standard test ASTM C-143
shall be used to measure slump. Compressive
strength of concrete at 28 days shall be 4000 psi.
All exterior concrete shall have air entrainment of
5% to 8% by volume per ASTM C-260. Retempering
delivered concrete will not be allowed. Concrete shall
be composed of:
1. Portland cement - Conforming to ASTM C-150,
Type IA or Type IIIA.
2. Aggregates: Conforming to ASTM C-33
3. Water - Shall be clear and free from
injurious amounts of oils, acids, alkalis,
organic materials or other deleterious
substances.
B. Welded Steel Wire Fabric - Where required for
concrete reinforcement shall conform to ASTM A185.
C. Premolded Joint Filler - Shall be of non
-extruding type meeting ASTM D-544 except that
premolded joint filler used in concrete walk
construction may be either non-extruding or
resilient.
D. Bituminous Pavement Materials - All materials
proposed for the construction of bituminous
pavements shall comply with the Indiana Department
of Transportation specifications, per latest
revision.
E. Compacted Aggregate Subbase: Shall be crushed
stone or gravel. Crushed gravel shall be a
minimum of 35% crushed material. Chert shall be
limited to a maximum of 8f the total. Material
shall be free from an excess of flat, elongated,
thinly laminated, soft or disintegrated pieces;
and shall be free from fragments coated with dirt.
Compacted aggregate shall be graded as follows:
SIEVE SIZE % PASSING
1-1/2" 100
1" 80-100
3/4" 70-90
1/2" 55-80
#4 35-60
#8 25-50
#30 12-30
#200 5-10
3. APPLICATION
A. Grading - Do any necessary grading in addition to
that performed in accordance with Earthwork
Section, to bring subgrades, after final
compaction, to the required grades and sections
for site improvement.
B. Preparation of Subgrade - Remove spongy and
otherwise unsuitable material and replace with
stable material. No traffic will be allowed on
prepared subgrade prior to paving.
C. Compaction of Subgrade - The first 6 inches below
the subgrade shall be compacted to at least 100%
of the maximum dry density as determined by the
provisions of AASHTO T-99. Water shall be
prevented from standing on the compacted subgrade.
F. Utility Structures - Check for correct elevation
of all manhole covers, valve boxes and similar
structures located within areas to be paved, and
make, or have made, any necessary adjustments in
such structures.
G. Placing Concrete
1. Subgrade - Place concrete only on a moist,
compacted subgrade or base free from loose
material. Place no concrete on a muddy or
frozen subgrade.
2. Forms - All forms shall be free from warp,
tight enough to prevent leakage and substantial
enough to maintain their shape and position without
springing or settling, when concrete is placed.
Forms shall be clean and smooth and coated with
form release before placement of concrete.
3. Placing Concrete - Concrete shall be
deposited so as to require as little
rehandling as practicable. When concrete is
to be placed at an atmospheric temperature of
35 degrees F. or less, paragraph 702.11 of
the Indiana Department of Transportation
Specifications latest revision shall be
followed.
H. Concrete Curb
1. Expansion Joints - Shall be 1/2 inch thick
premolded at ends of all returns and at a
maximum spacing of 100 feet.
2. Contraction Joints - Unless otherwise
provided, contraction joints shall be sawed
joints spaced 20 feet on center.
3. Finish - Tamp and screed concrete as soon as
placed, and fill any honey combed places.
Finish square corners to 1/4" radius and
other corners to radii shown.
I. Concrete Walks and Exterior Steps
1. Slopes - Provide 1/4 inch per foot cross
slope. Make adjustments in slopes at walk
intersections as necessary to provide proper
drainage.
2. Dimensions - Walks and steps shall be one
course construction and of widths and details
shown on the drawings.
3. Finish - Screed concrete and trowel with a
steel trowel to a hard dense surface after
surface water has disappeared. Apply medium
broom finish and scribe control joints at 5
foot spacing. Provide 1/2" expansion joints
where sidewalks intersect, and at a maximum
spacing of 40 feet between expansion joints.
J. Curing Concrete - Except as otherwise specified,
cure all concrete by one of the methods described
in Section 504.04 of the Indiana Department of
Transportation Specifications, latest revision.
E. Bituminous Pavement - Hot asphalt concrete
pavement shall be as specified in Section 400-410
of the Indiana Department of Transportation
Specifications latest revisions. Paving will not
be permitted during unfavorable weather or when
the temperature is not in compliance with section
D. Compacted Aggregate Subbase - the thickness shown
on the drawings is the minimum thickness of the
fully compacted subbase. Compaction shall be
accomplished by rolling with a smooth wheeled
roller weighing 8 to 10 tons. Compact to 95%
standard proctor density (ASTM D698)
Along curbs, headers and walls and at all placed
not accessible to the roller, the aggregate
material shall be tamped with mechanical tampers
or with approved hand tampers.
