exists, remove all topsoil and unsuitable material. Tamp or
lacing granular fill. Fill shall be placed in six inch layers
elevation. Side slopes of fill material shall not exceed one
feet horizontal. Where a cut condition exists, remove all top
soil and unsuitable material and remove subgrade to the proper elevation allowing
sufficient width to accommodate the forms.
D -1 Granular Base
Place a granular base of five inch minimum thickness on the prepared subgrade. The
base shall extend the full width of the sidewalk.
E. Forms
Side forms shall be of lumber of not less than two inches nominal thickness or steel of
equal rigidity. No 2 x 4 lumber forms will be permitted. Forms shall be held sec-
urely in place by stakes or braces with the top edge true to line and grade. The forms
for the sidewalk shall be set so that the slab will have a fall of one inch vertical to
four feet horizontal from the edge nearest the property line toward the edge farthest
from the property line, except as may be otherwise directed by the Village Engineer or
his representative.
F. Reinforcing
Reinforcing bars shall be embedded in the concrete at mid -depth in a longitudinal dir -,..
ection over all existing water or sewer services or other utilities buried beneath the
sidewalk. Three 3/4" diameter bars, each with a minimum length of ten feet shall be
installed over each utility. The bars shall be equally spaced across the width of the
sidewalk.
G. Expansion ..Joints =Page 4
Expansion'joints of the thickness speci:fied'below shall consist of a premoulded filler

thick shall be placed between the sidewalk and all structures
such as light standards, traffic light standards, and traffic
poles, which extend through the sidewalk.
2. Three- Fourth Inch Thick Expansion Joints. Expansion joints 3/4
inch thick shall be placed at intervals of 50 feet in the side-
walk and where specified by the Village Engineer. Where the
sidewalk is constructed adjacent to pavement or curb having ex-
pansion joints, the expansion joints in the sidewalk shall be
placed opposite the existing expansion joints.as nearly as prac-
ticable. Expansion joints shall also be placed where the side-
.walk abuts existing sidewalks, between driveway pavement and
sidewalk, and between sidewalk and curbs where the sidewalk
abuts a curb.
H. Placing and Finishing Concrete
1. Notify the Village when the subgrade has been finished with a minimum of 24
hours notice prior to placing concrete. No concrete shall be placed until
the subgrade has been inspected and approved by the Village.
2. The subgrade shall be moistened just before the concrete is placed. The
concrete shall be placed in successive batches for the entire width of the
slab, struck off from 1/2 to 3/4 inch higher than the finished slab, tamped .
until all voids are removed and free mortar appears on the surface,' thoroughly'
spaded along the edges, struck off to the true grade, and finished to a true
and even surface with floats and trowels. The final troweling shall be done
with a steel trowel, leaving a smooth, even surface. After the water sheen
has disappeared, the surface shall be given a final finish by brushing with a

the edges of the walk, with adjacent strokes slightly overlapping, producing a
uniform, slightly roughened surface with parallel marks.
3. Control joints shall be constructed at right angles to the center line of the
sidewalk (and shall extend to 1/4 the depth of the sidewalk) They shall not be
less than 1/8 inch nor more than 1/4 inch in width, and shall be edged with an
edging tool having a 1/4 inch radius. All slabs shall be five feet long on any
one side, unless otherwise ordered by the Village Engineer or his representative.
I. Protecting From Low Temperatures
After the first seasonal frost, protect concrete from,freezing for not less than 48 hours
after placing. The Contractor shall be responsible for all concrete damaged by low tem-
peratures and any concrete so damaged shall be removed and replaced by him at his expense.
J. Curing:
Sidewalks must be cured by one of the following methods:
A. Place burlap on the finished surface, saturate with water and cover with an
impermeable covering.
B. Place polyethylene sheeting as soon as the concrete has hardened sufficiently
to prevent marring of the surface. Wet the surface of the concrete immed-
iately before the sheeting is placed. The edges of the sheeting shall be
weighted securely with a continous windrow of earth or any other means-satis-
factory to the Village to provide an air tight cover.
C. Apply specified curing compound with brush, roller or spray at the rate of (1)
one gallon for every 250 square feet of sidewalk.
Any of the above curing methods must remain in place for not less than 6 days.
K. Backfill
After the concrete has been cured, forms shall be removed and the space near the edges
•IE. Back fiII : ( cont'd) Page 6
of the "sidewalk shall be backfilled to the required elevation with material approved by
the Village. The Material shall then be compacted until firm and the surface evenly
graded.

disposed of by the Contractor.
M. Control of Materials
The Contractor shall,,at his expense, have a Commercial Testing Laboratory prepare and
test samples of delivered concrete. One set of tests shall be taken for the first 25
cubic yards and one set of tests shall be taken for each 50 cubic yards. A set of tests
shall consist of 4 standard cylinders (two shall be broken at 7 days and two shall be
broken at 28 days) , one slump test and one air content test. The laboratory shall per-
form tests in accordance with recognized ASTM standards and shall submit written reports
of such tests to the Village for review.
