within the City of Evanston to be designated by the Engineer.
PREPARATION OF SUBGRADE: The subgrade shall be constructed so as
to have as nearly as practicable, a uniform density throughout its en-
tire width. Compression of the subgrade material shall be accomplished
by successive operations of a self-propelled tandem roller, weighing not
less than three (3) nor more than five (5) tons. Portions of the sub -
grade inaccessible to the roller shall be wetted and tamped solidly with
a hand tamp weighing not less than fifty (50) pounds and not to exceed
one hundred (100) square inches in area. All soft, spongy or yielding

0 .' 1
Rolling shall continue until the subgrade is uniformly compacted,
brought to a true shape and to an elevation uniformly eight (8) inches
. below the established grade and cross sectional contour of the top of
the pavement. Where the soil in the alley consists of sand or sandy
soil incapable of compaction by rolling or tamping, said compaction
shall be accomplished by thoroughly flooding the subgrade. After
being prepared in the above manner the subgrade shall be so maintained
until the pavement has been placed thereon.
CHECKING AND ACCEPTANCE: Immediately before the pavement is laid,
the subgrade shall be checked by means of an approved template, shaped
on the under side to conform to the lower surface of the finished pave-
ment, or by a method of testing approved by the Board of Local Improve-
ments. All high places shall be removed to true grade and any low places
filled with sandy soil and rolled or hand tamped until smooth and firm.
The subgrade shall be checked and completed in accordance with these re-
quirements for a distance of not less than one hundred (100) feet in
advance of the pavement. If hauling over the subgrade after it has been
finished and checked as specified results in ruts or other such ob-
jectionable irregularities, the contractor shall reroll or hand tamp
the subgrade and place it in smooth and satisfactory condition before
the pavement is deposited upon it. If the condition of the subgrade is
such that it cannot be placed in satisfactory condition to receive the
pavement, paving shall be stopped by the Engineer unless the contractor
provides and hauls over suitable trackways or uses other means for the
protection and maintenance of the subgrade. The cost of subgrade prepara-
tion and all excavation and replacement required by these specifications
shall be included in the unit price bid for Special Excavation.
SEWER CONNECTIONS: All existing connections to the present sewer
• shall be protected against damage during the construction of this proposed
improvement. Any connections damaged shall be repaired immediately by
the Contractor at his own expense.
TRENCH BACKFILL: This item shall consist of furnishing sand or
stone screenings from beyond the limits of this improvement, placing it
where directed by the Engineer and puddling same with water until settle-
ment is complete. It shall be used for backfilling trenches, between
new retaining walls and existing foundation walls, building foundations,
water main excavations and any other cavity which may occur in the area
of this improvement or where the inner edge of a trench is within two
feet of the edge of this improvement.

ment cross section with an eight (8) inch uniform thickness. Contract
unit price for PORTLAND CEMENT CONCRETE PAVEMENT shall include payment
for all material, labor and equipment necessary for the construction of
this pavement.
LONGITUDINAL CENTER JOINTS: The concrete pavement shall be built
so as to have a longitudinal center joint. Said longitudinal joint shall
extend along the center line of the pavement the entire length of the im-
provement. The joint shall be made by installing a specially built metal
strip which will separate the concrete. The said strip shall be made of
No. 18 gauge sheet steel seven and one-half (72) inches in width, and
shall be delivered on the work in ten (10) foot lengths. Said strip shall
have a trapezoidal corrugation along the center therof, two and one-half
(22) inches in vertical dimension and one (1) inch in horizontal dimension.

• by means of metal clips. Said strip shall extend vertically from the base
of the concrete pavement to one-half (2) inch below the top of the finished
surface of the pavement and shall be held securely in vertical position to
straight alignment, by means of steel pins, left in place, driven vertically
through holes punched through said strip and not to exceed two and one-half
(22) feet centers. The pins used shall be three -eights (3/8) inch in dia-
meter and not less than fifteen (15) inches in length. Deformed steel tie
bars one-half (2) inch in diameter and two and one-half (22) feet in length
shall be placed through the longitudinal joint in openings punched for
that purpose, which openings shall be along the center line of said strip
so spaced as not to exceed two and one-half (22) feet centers. Each bar
shall be held rigidly in horizontal position during the placing of the
concrete by the use of two (2) metal bar chairs driven into the subgrade.
A template shall be used to install the strip vertically to straight
alignment prior to the deposition of the concrete and the joints shall
not be displaced during the finishing operation. Furnishing all material,
labor and equipment for installing of said longitudinal joint and tie
bars shall not be paid for directly, but shall be considered incidental
to the construction of the Portland Cement Concrete Pavement.

TRANSVERSE EXPANSION JOINTS: Transverse expansion joints shall be
• placed throughout the entire improvement across the concrete pavement
at right angles to the center thereof and at intervals of one hundred
(100) feet measured along said center line. The expansion joints shall
be made by placing and leaving in place prior to laying the concrete
mixture for the pavement, a bituminous premoulded joint filler con-
forming to the requirements of Article 129.4 or 129.5 of the "Standard
Specifications.t4 Said joint filler shall be three fourths (3/4) inch
in thickness and shall extend vertically from a point one (1) inch
below the top of the subgrade to a point one half (1) inch below the
finished grade of the pavement. The intervening space between the
top of said joint filler and the finished grade of the pavement shall
be filled with Asphalt P.A.F.-3.
Load transfer across said expansion joints shall be accomplished
by installation of three -fourths (3/4) inch round smooth steel bars
eighteen (18) inches long at fifteen (15) inch centers through said
joint filler, or by other load transfer device approved by thb Engi-
neer. One end of each of said steel bars shall be furnished with a
metal or fibre cap to provide one (1) inch of expansion space. Said
steel bars shall be maintained rigidly in proper alignment by approved
means.
All manhole frames and other fixed objects, with the exception of
frames otherwise mentioned in those specifications, shall be separated
from the concrete pavement by a joint filler of the same thickness and
character as hereinbefore specified for expansion joints, which joint
filler shall extend through the entire thickness of the pavement.
Said joint filler shall be placed in such a manner as to form a square
• whose sides will be fifteen (15) inches from the upper outside edges
of the frames.
Furnishing all labor, equipment, and materials for installation
of said expansion joints. Load transfer devices and reinforcing steel
shall not be paid for directly, but will be considered incidental to
the construction of the Portland Cement Concrete Pavement.
CONTRACTION JOINTS: Sawed contraction joints or other type of
contraction joints which may be approved by the Engineer, shall be
placed throughout the entire improvement across the concrete pavement
at right angles to the center thereof at intervals of twenty-five (25)
feet between expansion joints and in accordance with the detail shown
on plans.
Furnishing all labor, equipment, and materials for the installa-
tion of said contraction joints including dowel bar assembly shall not
be paid for directly, but will be considered incidental to the con-
struction of the Portland Cement Concrete Pavement.

o�_,J
MIXING AND PLACING CONCRETE: Concrete shall be mixed and placed
• in accordance with the requirements of Section 48 of the tiStandard Speci-
ficationstt, insofar as the same may apply. While being placed the con-
crete shall be vigorously sliced and spaded to eliminate voids or honey-
comb pockets. The concrete shall be especially well spaded and tamped
against forms and bulkheads. The concrete shall be struck off, so that
the upper surface shall conform to and be sufficiently higher than the
contour.herein specified for the upper surface of the finished pavement,
to give the specified thickness of pavement herein required. The strike
board shall be moved forward with a combined longitudinal and transverse
motion, and so manipulated as to tamp the concrete thoroughly. A slight
excess of material shall be kept in front of the cutting edge at all times.
The entire area of the pavement shall be struck off and tamped, so executed
as to insure maximum compaction.
FINISHED CONCRETE: After the tamping has been completed, the pavement
shall be rubbed smooth of all ridges and depressions and brought to a true
and even surface by the use of wooden floats. A split float, shaped on
the under side to conform to the contour of the pavement, shall be used
for finishing the concrete on both sides of the longitudinal joints, here-
inbefore specified. The edges adjoining the transverse expansion joint
and the form, shall be tooled with an edging tool, having a radius of one -
quarter () inch.
After the floating has been completed, the surface of the pavement
shall be tested with a notched straight edge, ten (10) feet in length.
This straight edge shall be placed over the transverse joints and between
the same at frequent intervals, parallel to the center line of the pavement
and moved across from side to side. Any variation in excess of one -eighth
• (1/8) inch above or below the general established contour of the pavement
shall be rubbed with a long handled float and the irregularities corrected
until the straight edge shall show a bearing for its entire length.
Workmen shall not walk on freshly laid concrete and no one shall be
allowed on the concrete after it has been worked into form and shape until
it has entirely hardened. The entire surfacing of the concrete pavement
shall be done from a bridge, not less than one (1) foot in width which
shall not come in contact with the concrete pavement at any point. Two
(2) of said bridges shall be provided for each concrete mixing gang. Two
bridges shall be maintained in constant readiness to be immediately moved
into position, to provide access for finishing, tooling and edging joints,
adjusting filler and refinishing damaged portions of the finished surface.
PROTECTION AND CURING: Protection and curing shall comply with the
requirements of Section 48 of the "Standard Specificationstt.

• sewer pipe or concrete sewer pipe shall be laid as hereinafter specified.
Said sewers shall be laid in open trenches in the ground in such
manner as to conform to the elevations, lines and grades hereinafter
specified in accordance with the requirements of Section 66 of the
19Standard Specificati.ons,99 and shall be designated as Storm Sewers Type-2.
The pipe used in the construction of said sewers shall be of the
type known as "Bell and Spigot" having an internal diameter of 8 & 10
inches. Where required for connections from catch basins or manhole -
catch basins, 844 94Y" branch shall be furnished and set in said sewer..
The material excavated shall be kept compactly along the sides of
the trenches and shall be backfilled as soon as practicable in order to
occasion the least possible inconvenience to the public in the use of
the street or alley as the case may be, but prior to said backfilling
and immediately after the laying of the pipes, bank sand shall be
carefully packed under, around and over the pipes in such manner as to
compactly fill the trenches to a depth of twelve (12) inches above the
top of the pipes. Where material excavated is not such as can be readily
compacted in said trenches, same shall be replaced with bank sand, as
directed by the Engineer.
The open and unconnected ends of said sewers shall each be securely
closed with a salt glazed, vitrified tile disc and sealed in the manner
specified for joints between pipes.
BASIS OF PAYMENT: This work will be paid for at the contract unit
price per lineal foot for Storm Sewer Type-2, of the diameters specified,
measured in place, which prices will be payment in full for all trench
excavation, backfilling with excavated material or bank sand, and for
all labor, materials and equipment, including 44V' branches, to complete
