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
placed 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 of 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, alkalies,
organic materials or other deleterious
substances.
B. Welded Steel Wire Fabric - Where required for
concrete reinforcement shall conform to ASTM A185.
C. Premoulded Joint Filler - Shall be of non
- extruding type meeting ASTM D -544 except that
premoulded 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 8% of 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 AASHO T -99. Water shall be
prevented from standing on the compacted subgrade.
D. 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.
E. 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 immediately before
concreting.

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 702.10 of
the Indiana Department of Transportation
Specifications latest revision shall be
followed.
F. Concrete Curb
1. Expansion Joints - Shall be 1/2 inch thick
premoulded between storm structures & curb.
2. Contraction /Control Joints - Unless otherwise
provided, contraction joints shall be sawed
or scored joints spaced 10 feet on center, except for
intersection radii where joints shall be placed 5' o.c.
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 comers to radii shown.
G. 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 48 feet between expansion joints.
H. Curing Concrete - Except as otherwise specified,
cure all concrete by one of the methods described
in Section 501.17 of the Indiana Department of
Transportation Specifications, latest revision.
1. Bituminous Pavement - Hot asphalt concrete
pavement shall be as specified in Section 403 of
the Indiana Department of Transportation
Specifications latest revisions. Paving will not
be permitted during unfavorable weather or when
the temperature is 40 degrees F. and falling.
J. 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 90%
compaction using Standard Testing Procedures.
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.
