FOR CEMENT CONCRETE PAVEMENT.
SECTION.1. PLANS: The detailed location of the work to be done,
together with grades, cross — sections and special construction,
is illustrated on the maps, profiles, cross — sections and plans
adopted therefor by the City Council, and on file in the office of
the City Engineer. These maps, plans, profiles and cross — sections
are to be considered a part of these specifications, and any
notations appearing the�reon shall be considered as though in-
corporated as a part df these specifications. All distances and
measurements given are in a horizontal plane. All work shall,
during its progress and on its completion, conform to the lines
and levels which may from time to time be given by the City Engineer.
SECTION 2. GENERAL REQUIREMENTS: The general requirements shall
conform to Standard Specifications No. 50 for : "General Requirements"
SECTION 3. WORK: The work to be done consists of the following:
(a) To excavate or fill in the area upon which the pave-
ment is to be constructed, to such an extent and in such a manner
as may be required by the maps, plans, profiles, cross— sections
and these specifications.
(b) To construct thereon the pavement as provided for on
the maps, plans, profiles, and cross— sections.
(c) To furnish all material and labor necessary to perform
said work and to complete same.
(d) Removing from the street and sidewalk adjacent to the
work, all surplus material or debris.
SECTION 4. GRADING:.
(a.) GRADING AREA: Unless otherwise specified by plan, reso-
lution or ordinance,.the street shall be graded from property line
to property line along portions of the street upon which pavement
is to be constructed, excepting no grading need be done between
curb and property line along such portion of the street where curb
and sidewalk have already been constructed. The roadway between
curb lines shall be brought to the subgrade required by the plans or
these specifications. The spaces between the curb lines and the
property lines.in cases where no aidowalks are to be constructed
shall be graded to a plane rising at a rate of one (1) inch in
four (4) foot from the established grade at the curb line.
Side slopes of cuts and fills shall be neatly and
accurately trimmed to true cross— section.
(b) ROUGH GRADING: Rough grading shall include all filling
and removal of excess earth, stone, trees, old pavements, curbs,
sidewalks, driveways, culverts, and any other structures or foreign
materials that may be encountered in preparing the street for the
improvements to be,made.• oy
t
Plowing or excavating sound material shall not be done
to a depth greater than six (6) inches below subgrade.
• On any street where the improvement of the roadway is
. specified, the rough grading in any block shall be completed and
the surface leveled up approximately to final subgrade or grade
before the construction of any cement work is begun in such block.
E:aeavated material not required for fills shall be removed from the
street as soon as excavated.
All material removed to facilitate construction shall
be replaced to grader
FILLS: The space over which fills are to be made shall
first be cleared of all brush, trees, stumps, timber, trash or
debris. All filling shall be done with good sound earth, sand or
gravel, and no oil cake or other lumpy material, or material of a
perishable, spongy or otherwise improper nature shall be used in
filling.
Fills shall be made as the Engineer may direct, either
by flooding or rolling.
For rolling, the material
exceeding one (1) foot in depth before
being leveled'offi shall be thoroughly
moist throughout, shall be rolled with
compression of at least four hundred
tire.
shall be placed in layers not
rolling. Each layer, after
dampened, and while still
a ower roller having a
&00; pounds per inch width of
When flooding is reqguired, the material shall be brought
up in layers not exceeding four (4) feet in depth and each layer
thoroughly flooded with water and barred.
No fills shall be widened by dumping loose material
over their slopes. When a fill is to be widened, the new material
shall be bonded to the old by cutting steps into the existing slope
and by bringing up the layers as specified above.
MUD AND SOFT MATERIAL: -When an area of mud, or other
soft or spongy material is encountered, it shall be removed and
the space filled with gravel or good earth, which shall be placed
in layers and rolled as hereinbefore set forth for fills until the
surface ceases to move or creep under the roller. The Contractor
will not be required in suah cases to excavate mud or other soft
or spongy material to a depth greater than two (2) feet below
grade.
Where such a soft spot is caused by a leak in water
main or pipe, the soft material shall be excavated down to the
pipe and after the pipe has been repaired, the excavation shall be
back — filled with good material properly tamped or rolled. When-
ever any area is too wet to permit of thorough rolling or tamping
the Contractor shall wait until the material has dried sufficiently
and then complete the rolling or tamping.
(c) SUBGRADE: After the rough grading has been completed,
the surface of the subgrade shall be brought to the required grade
and cross — section, and the subgrade prepared as follows:
After a block or section has been graded to approx-
imate grade, the surface of the roadway shall be thoroughly cult-
ivated to a depth of not less than ten (10) inches, 4nd all rocks
four (4) inches in diameter or.Larger, and all rubbish shall be
removed. During or after cultivation, water shall be applied until
the moisture has penetrated to the entire depth of cultivation.
—2—
i
The roadway shall then be thoroughly rolled with a
power roller weighing not less than twelve (12) tons, until the
. surface ceases to move or creep under the roller. All depressions
shall be filled with good earth.
After the first rolling, the subgrade shall be
thoroughly cultivated to a depth of not less than four (4) inches
and water applied during cultivation until a uniform dampness
of four (4) inches is secured. The Street Superintendent may re-
quire a disc cultivator for work in clay or adobe soils. While
.the subgrade is still moist, it shall be thoroughly rolled with a
power roller weighing not less than twelve (12) tons until the
surface is firm and unyielding and ceases to move or creep under
the roller, and until it is brought to true grade and cross — section.
After the final rolling, as specified above, the fill-
ing of low places will not be permitted. Portions of the roadway
which cannot be reached by roller shall be tamped solid. When a
grade has been prepared and checked and found to be low, it shall
be loosened up with a harrow or disc before any additional layer of
earth is placed thereon.
Subgrade which has been checked and approved must be
re— rolled, re— checked, and approved after a rain storm.
If the subgrade consists of sand, the rolling there-
of will not be required, but it shall be compacted by thoroughly
wetting down and smoothed to conform to cross — sections.
(d) CONDITION OF STREET DURING GRADING: During the grading
the surface of the street crossing shall be maintained in a
reasonably good condition for traffic. Proper drainage must be
maintained at.all times. Where there is a car line, suitable
landing places shall be left for passengers as long as possible.
(9) CITY ENGINEER TO CHECK GRADING! The Contractor shall
notify tho City Enginoor when a block or a section has.bo„n brought
to subgrado, whereupon the latter will chock the elevation and
condition of the same. If the work is found to be in accordance
with the specifications and grades givon, the contractor shall pro-
ceed as hereinafter montionod. .
SECTION 5. MATERIALS: Cement, sand, gravel and rock shall con-
form to Standard Specifications No. 51 for "Portland Cement ", "Sand ",
"Gravel" and "Rock" respectively.
WATER: Water shall be clean, free from oil, acid,
alkali or vegetable matter.
SECTION 6. CEMENT CONCRETE:
(a) PROPORTION: The concrete to be used in constructing
the pavement herein specified shall be composed of the following
materials, and in the following proportions, to —wit.
1. One sack of cement weighing ninety —four (94) pounds.
2.. 535 pounds of dry mixed aggregate, 15 per cent by
weight of which must be retained on a 1" screen having
square openings.
3. Not more than 6.0 gallons of water, which will in-
clude the water in the aggregate.
The percentage of rock and the percentage of sand con-
tained in the above mixed aggregate shall be determined by the
—3—
f p`S
i ".ollowing formulas; —
C (A- -K
A —B
D 100 — C
Where A is the fineness modulus of the rock.
B is the fineness modulus of the sand.
C is the po:ecentage by weight of the sand in the mixed
aggregate when dry.
D it the percentage by weight of the rock in the mixed
aggregate when dry.
K = 5.80 when 15 per cent or more by weight of the dry mixed
aggregate is retained on a 1 inch screen with square
openings.
K e 6.2 when 15 per cent or more by weight of the dry
mixed aggregate is retained on 'a 1j inch screen with
square openings.
K e 6.5 when 15 per cent or more by weight of the dry mixed
aggregate is retained on a 2 inch screen with square
openings, or when 25 per cent or more by weight of the
dry mixed aggregate is retained on a 12 inch screen
with square openings.
The fineness modulus of the rock and of the Sand shall
be determined in accordance with.5tdnda,rd Opodificatious NO. 51
v£ tho Eitq of HoTiporl Beach. 1ho.:weights of mixed aggregate above
specified are for dry material and the weight of the moisture con-
tained in said material must be deducted in order to obtain the
weights above specified for dry material. Determinations for
finangtis' modulus and moisture will be made by the City Engineer
and will be open to the contractor.
Each cubic yard of concrete in place shall contain not
less than six (6) sacks of cement.
(b) MEASURING MATERIALS: The sand and rock shall be kept
in separate bins, compartments or piles, and said materials shall
be carefully weighed in the proportion specified by means of mul-
tiple beam or dial scales.
The Contractor will not be permitted to deposit or store
any sand or rock on the sub— grade, but the concrete material, after
being weighed, must be discharged directly into a truck or wagon
and from there discharged directly into the skip of the concrete
mixer.
(c) MI$ING CONCRETE: Machine mixing of concrete shall be
done with mechanical batch mixers only, which shall be equipped
with an automatic timing device so constructed that it is put
into operation when the mixer skip is raised to its full height
and shall ring a bell and release the discharge lever after the
specified time of mixing in the drum has elapsed.
The water tank on the mixer shall be so arranged that
the amount os water required for each batch of concrete can be
positively and accurately measured and while the water tank is dis-
charging the inlet supply shall be automatically cut off.
—4—
N i
r
Mixers shall be of the boom and bucket type, in which
the concrete is conveyed from the mixer in a bottom dump bucket
and deposited upon the subgrade, No chuting of concrete will
be permitted.
• All pick —up and throw —over blades in the drum of the
mixer which are worn down three— r�uartern (3/4) of an inch or more
must be replaced by new blades.
The drum of the mixer shall revolve at a rate of speed
not to exceed the rated speed specified by the maker of the mixer
provided, however, that the drum shall make not less than ten (101
nor more thari eighteen (18) revolutions per minute.
The Contraoto=s shall mix in the mixer only such quan-
tity of material as will in the opinion of the Street Superin-
tendent be within the capacity of the mixer without spilling, based
on the water level capacity of the drum, but in no case shall the
amount mixed exceed the manufacturer's catalog rated capacity.
No splitting of sacks of cement will be allowed in
mixing concrete, and every batch of concrete shall be mixed in the
drum of the mixer not less than seventy (70) seconds before any
portion of the batch is discharged from the said drum. The drum
shall not be charged while mixer is discharging..
In mixing concrete, the materials shall be mixed with
sufficient water to produce concrete with a slump not to exceed
two (2). inches when tested by a truncated cone form. The test
cone to be used in making the slump test shall have an inside
diameter of eight (8) inches at the base and an inside diameter
of four (4) inches at the top, and a perpendicular height of
twelve (12) inches. Immediately after the concrete has been
mixed and deposited on the sub — grade, a sufficient quantity
thereof shall'be placed in four layers in the tapered test cone
until the concrete is flush with the top of the cone, each layer
shall be thoroughl, settled by working with a pointed iron rod.
Then the test cone shall be lifted, allowing the concrete to
settle or slump. After the pile of concrete has set one (1)
minute, its height shall be measured and subtracted from the
original height of twelve (12) inches, which difference in height
is the amount o the slump in inches.
No concrete shall be used which has paritally set and
no concrete shall be retempered or remixed.
SECTION 7. CONSTRUCTION OF PORTLAND CEMENT CONCRETE PAVEMENT• —
Portland cement concrete pavement shall consist of concrete pro-
portioned and mixed as hereinbefore set forth.
Where the area of pavement to be laid is more than one
thousand (1000) square feet, a concrete mixer must be used. The
thickness of finished pavement shall be as shown on the adopted
cross — section and as required by resolution or ordinance.
(a) FORMS: Before placing forms the earth beneath them
shall be excavated to the proper grade, and shall be hard and com-
pact. Forms shall have full bearing upon the earth throughout their
length. The top edges of all forms shall conform to the grades
and cross sections of the surface of the pavement.
Side forms of timber or steel must be used. They shall
be placed with exactness to the required grade and alignment of the
top edges of the finished pavement and be so supported during the
entire operation of placing, tamping and finishing the pavement
—5—
that they will not at any time deviate lat rally nor at any time
deviate vertically more than one— quarter (�) inch from the proper
line.
• When side forms are used more than once, only straight
forms shall be used and all warped forms and split timber forms
shall be discarded.
Before being placed, all forms shall be thoroughly
cleaned.
Timber side forms shall be I4o. 1 common Qregon pine or
white fir. They shall be not less than two (2) inches thick, and
at least sixteen (16) feet long, and their depth shall be at least
equal to the specified depth of the edge of the pavement. If the
Contractor so elects, he may have the timbers sized, but the depth
of such timbers, after sizing, shall be not less than the above
specified dimension, Their shall have square top edges, s quare butt
joints, and shall not contain enough knots or other imperfections to
impair their strength. They shall have no wane on the edge to
be placed uppermost, and shall be straight.
Timber side forms shall rest upon two (2) inch by three
(3) inch stakes, spaced not greater than four (4) feet apart,
driven with their tops to the line and grade for the bottom of the
side form. Stakes for nailing on the outside shall be placed not
more than four (4) feet apart at the intermediate points.
Timber side forms shall be secured by side stakes not
less than three (3) inches in width, one and one —half (1J) inches
in thickness, and not less than eighteen (18) inches i.n length.
The length of stakes shall be increased when the character of the
soil will not give sufficient bearing to an eighteen (18) inch
stake. Side forms shall be staked at intervals not greater than
four (4) feet.and the tops of the stakes shall be one (1) inch
below the top edge of the side forms. Side forms shall be spliced
with a section of timber two .(2) feet in length, one (1) inch
thick and six'(6) inches bride, which shall be nailed lengthwise,
lapping the joints. Side stakes shall be securely nailed to the
forms.
Metal side forms for this work shall be straight, flee
from warp, of heavy section, with sufficient rigidity to prevent
springing during the placing and tamping of the concrete. Their
depth shall be equal to the specified depth of the edge of the
pavement.
Metal side forms shall be supported at each end by a
two (2) inch by three (3) inch stake, driven with its top to the
line and grade for the bottom of the side form. Metal side forms
having a bottom flange less than six (6) inches in width shall
rest upon stakes, as above provided, spaced not greater than five
(5) feet apart.
Metal forms shall be staked firmly by means.of steel
stakes s, aced not greater than four (4) feet apart and shall be
so designed that stakes may be driven through the base of the form
and locked in position. Forms in which the stakes merely hold
down the edge of the form will not be approved. Form joints shall
be so designed that a perfect support is obtained and in case
joints c?0 not. furnish such support the Contractor shall be required
to either substitute acceptable forms or, with the approval of the
Street Superintendent, wedge the forms with wood and provide double
,gupporting stakes underneath the ends.
—6—
r �
'Ide forms must be trued up and maintain�;a to the re-
quired line aud. grade in advance of .lacing concrete for a dis-
tanco of one day's run of tho mixer, and the Contractor shall
provide expert side form men for this purpose. when side forms
do not conform to the correct line and grade, or have become
loose, this shall always be considered suficient cause to stop
the work, until the fault is corrected.
Timber forms shall be left in place as a part of the fin-
ished work except where the pavement terminates against a curb,
gutter, building, or another pavement, in which case the forms
shall be removed immediately after striking off and tamping the
surface of the pavement as hereinbefore specified and the spaces
left thereby immediately filled with concrete and finished with
a float smooth and true to grade and adopted cross — section.
Whenever the pavement does not terminate against a curb,
gutter, building, or other pavement, the Contractor shall pro-
vide and lay upon the line of said termination, a header of
sound plank two (2) inches in thickness, and of a width not loss
than the thickness of the pavement. The top edge of the plank
shall conform to the street cross — section when finished. Said
headers shall be considered a necessary part of the pavement and
shall remain in place until replaced by permanent improve-
ment', unless otherwise noted on the plans for the pavement.
Side forms, except the false forms set against curbs or
buildings, must remain in place for at least twelve (12) hours
after placing the concrete.
All forms shall be oiled or set immediately before con-
crete is deposited against them. .
(b) PLACING: The concrete shall be spread to the re-
quired depth upon a thoroughly dampened subgrade prepared as here-
inbefore specified.
On roadways twenty (20) feet or lees in width, the con-
crete shall be laid across the entire width of the roadway in one
operation unless otherwise specified on said plans.
On roadways more than twenty (20) feet and not exceed-
ing fifty (50) feet in width, the concrete shall be laid across one-
half (2) the width of the roadway in one operation, A joint being
made along the center line of said roadway by using an intermediate
form along said center line, unless otherwise specified on said plans.
On roadways more than fifty (50) feet wide, the width
of concrete to be laid in one operation shall be as particularly
designated upon said plans.
The subgrade shall be thoroughly dampened immediately
ahead of the placing of the concrete, but no pools of water or
chopped up subgrade will be permitted.
Whenever it is necessary to stop the mixing and placing
of concrete for a period of thirty (30) minutes, or longer, a
header shall be set at tight angles to the center line of the
street and extending across the full width of the pavement and
the concrete shall be brought to a square joint.
A steel shod wooden subgrade templet tmrV -.*C the true
crown and shape of the surface of the subgrade shall be used behind
the mixer and in front of the placing of the concrete. This templet
—7—
OW
s �
ohall ride upon the L3 de forms and a7.1 high portions of the subgrade
shall be mae.e to conform to it. The filling in of low apots in the
• ,- .bgrade with loose material will not be permitted except as here -
i..nbefore provided.
• Tine concrete shall be thoroughly spaded against the
forms and joint filler.
(c) FI14ISHING: By means of templets, belts, floats,
trowels and such other implements as may be necessary, the concrete
shall be brought to a solid; compact mass and to a true, uniform aria
dense surface covered with mortar and conforming to the required
grade and cross— section. This surface shall be free from any un-
evenness greater than one — fourth (4) inch measured from a straight
edge fifteen (15) feet in length placed on the surface of the pave-
ment parallel to the center line of the street, except at street or
alley intersections or other places not intended to be straight lines.
Finishing shall be done in the following manner, unless
oth0rrise erecifiea on said plans:—
1st. Immediately after placing the concrete upon the
subgrade and before the initial set has taken place, the concrete
shall be struck o--,'f and tamped until it has become a solid, compact
mass, by means of a templet or mechanical tamper used at right
angles to the center line of the street. In places where the
mechanical tamper or templet above specified cannot be used, such
devices and methods shall be used as are necessary to bring the
concrete to the required grade and cross — section and to insure a
solid, compact mass and a true and iniform surface. Excess con-
crete shall be removed and any.low places in the surface of the
concrete shall be filled with sufficient concrete to bring the
surface to the required grade.
The tamping templet shall consist of a heavy plank,
the length of which is not less than the width of the pavement to
be tamped, nor greater than the width of the pavement to be
tamped, plus one (2.) foot. The tamping surface of the templet
shall be shod with a heavy strip of metal and shall conform to
the cross — section of the pavement. It shall be constructed so as
to be rigid and prevent sag.
If a mechanical tamper is used, it shall be an approved
automatic tamping or kneading and finishing machine operated by
a man experienced in the handling of the particular make of
machine in use, and operated at a speed not to axeeed that recom-
mended by the manufacturer.. The subgrade templet, tamping templet,
and tamper boards of the mechanical tamper shall, at frequent in-
tervals of time be tested for shape. In making these tests the
templet and tamper boards shall be placed in the same relative
position that thee' occupy when in use, and in no case shall they be
tested when turned upside down. In case they deviate from the re-
quired cross— section, they shall be immediately corrected. If the
proper correction can not be made, they shall be discarded and new
• ones placed in service by the Contractor.
After tamping, as above specified, the surface of the
pavement shall be thoroughly floated with long handled wooden
floats and this operation shall be continued as the Street Super-
intendent may direct.
2nd. A straigght edge float not less than fifteen (15)
feet nor more than twenty (20) feet in length with a troweling or
smoothing surface not less than six (6) inches nor more than ten
(10) inches in width, shall then be used on the surface of the
concrete with its length parallel to the center line of the street
and operated from bridges, with a combined longitudinal and trans-
verse motion, planing off the high places and filling in the
depressions..

During the forward progression of the floating operation
,ae longitudiiiF.l float rm�st not be advanced over two -- thirds of
• it:, length, giving a lap of one -third the length of.the float.
Imo, after such -planing, low places are discovered in
• the surface o' the concrete, additional concrete shall be added to
fill in and bring said low places to grade.
The use of the longitudinal float will not be required
in street intersections or other inaccessible places.
3rd. The surface of the concrete shall be finally fin-
ished smooth and true to grade and adopted cross - section by two
applications of heavy four (4) ply canvas belt, not less than
eight (8) inches in width and not less than two (2) feet longer
than the width of the pavement to be belted. The belt shall be
applied with a combined crosswise and longitudinal motion. For
the first application, vigorous strokes at least twOlve (12)
inches long shall be used, and the longitudinal movement of the
belt along the pavement shall be very slight. The second appli-
cation of the belt shall be immediately after the water glaze
or sheen disappears from the concrete and it has become slightly
sticky, and the stroke shall he not more than four (4) inches
and the lingitudinal movement shall be much greater than for
the first belting. In places where belt finish of pavement as
specified above, can not be used, the surface of the pavement
shall be finished smooth and true to grade with a wooden float.
The finished pavement shall be such that when tested by
a ten (10) foot straight edge held longitudinally with the
pavement, variations in excess of one - quarter (k,) inch will
not show. This does not apply to crowned intersections or at
points where a change of grade occurs.
After mixing has stopped, the finishers Shall remain late
enough to finish the pavement when the concrete has hardened
sufficiently, as herein provided.
4th: All upper edges of the pavement, including the
edge adjacent to the curb or gutter shall be rounded off to a radius
of three - eighths (3/8) of an inch with an edging tool and the
tool marks broomed.
The Contractor shall stamp his name and the year.built
on the pavement at the beginning and end of each block. The
letters shall not be less than two (2) inches in height and im-
pressed to a depth of three- eighths (3/8) of an inch.
(d) EXPANSION AND CONTRACTION JOINTS: Expansion and
contraction joints skull be constructed in the pavement by in-
serting therein during construction and leaving in place the
joint filler hereinOfter specified.
(1) LONGITUDINAL JOINTS: The joint filler for long-
. itudinal joints shall be one - quarter (4) of an inch thick, Out to
the full depth: of the edge of the pavement and shall be placed
• longitudinally along the street between adjacent slabs of the
pavement as particularly indicated upon said plans. Placing of
joint filler between the curb and pavement will not be required.
(2) TRANSVERSE JOINTS: Unless otherwise shown on said
plans, transverse expansion joints or "through joints" shall be
constructed in the pavement at intervals of sixty (601 feet. The
joint filler for "through joints" shall be one -half ( -g) of an inch
thick and shall be cut to a depth of one- fourth(4) inch less than
the full depth of the section of pavement.
IM
01he thickness of the joint filler shall be as above
• p�c:.fiea uri, ^e, o'herwlse shown on '-he plans.
• ;'Through Joints" shall be constructed as follows:- The
position of the transverse joints shall be marked on the forms on
each side of the pavement at U-he locations called for on said
plans :.i:-these specifications. A metal holder 1/8 inch to 1/4
inch thick cut to the cross - section of the pavement shall be
securely staked in place normal to the center line of the pave-
ment and perpendicular to the 'finished surface of the pavement. The
Joint filler shall then be placed in the holder and held firmly
in place with stirrups, angles, pins, outstanding lugs, or any
other means that will not interfere with the removal of the holder
nor cause the expansion material to be pulled out of place, when
the holder is removed.
After the joint filler has been securely, staked in
place, the concrete shall be deposited on both sides of the section
and struck o:_'= with the templet, before the holder is removed. The
holder shall not be removed until after the tamping templet and
longitudinal float have passed over the section. The'holder shall
be removed by slowly lifting from one end and replacing with con-
crete as it is lifted so that the joint filler will be left with the
lower edge resting on the subgrade and the upper edge.1/4 inch be-
low the finish surface of the pavement. The pavement shall then
be finished over the joint as hereinbefore provided for in these
specifications.
After the pavement.has.been finally finished the con-
crete shall be cut through with a jointer or other took, leaving
the joint filler exposed for its total length and width. The joint
thus opened shall be straight and any stones encountered shall
be removed and new concrete mortar troweled into place leaving a
clean open joint. The slabs on both sides of an expansion
joint shall be finished with an edging tool to a radius of
three - eighths (3/8) of an inch. True surface alignment of concrete
on both sides of the joint must be maintained.
Transverse contraction joints or "dummy joints" shall
be constructed in the pavement at intervals of twenty (20) feet be-
tween transverse expansion joints, unless otherwise shown upon
said plans. The joint filler for "dumg joints" shall be one -
quarter (w) of an inch thick and two (2 inches in width.
"Dummy Joints" shall be constructed as follows:- The
position of the joints shall be marked on the forms.on each side
of the pavement at the locations called for on said plans or
these specifications. After the application of the first canvas
belt, as hereinbefore provided for, a groove approximately 21
inches deep shall be made in the pavement at the location of the
joint by means of a 3" x ail' x 3/8" T -bar equipped with plow
handles and properly supported to hold to the true shape of the
roadway section. The T -bar shall remain in the concrete until the
concrete has set sufficiently to remain open while the filler is
• being inserted. The strip of joint material shall be. inserted
2z inches deep into this groove and the concrete floated smooth
over the joint.
After the pavement has been finally finished., as herein -
before provided, the concrete shall be cut through with a jointer
leaving the joint material exposed. The joint thus opened shall
be straight, and any stones encountered shall be removed and new
concrete mortar troweled into place, leaving a clean, open joint.
-10-
O _
The slabs on both sides of a contraction joint shall be finished
• a1 .tb. an edgi__,; tout. to a radius o.f three— eighths ( 3/8) of an inch.
rue surface alignment of'the concrete un both sides of the joint
• mr,st be maintained.
(e) CURING: immediately after the pavement has been
finall- finished and edged it shall be entirely covered with one
thickness of seven (7) ounce burlap, previously dampened, proper
care being taken not to make ridges in the finished surface of
the pavement. The burlap shall not be dragged or pulled across
the fresh concrete. This burlap covering shall be sprinkled with
water by means of an adjustable garden hose nozzle, so adjusted
that it will spray- and the burlap shall be kept wet until removed.
The Contractor shall provide with each mixer on "the
work, sufficient burlap to cover the maximum amount of pavement
laid in one (1) days run. This burlap shall be used exclusively
for covering pavement, and shall be replaced by now burlap when
deteriorated..
After the concrete pavement has hardened sufficiently
so that the earth will not become incorporated in the surface of
the concrete, the burlap shall be removed and the curing of the
pavement shall -be continued by means of earth dykes, earth
blanket, or sprink'.ing in the following manner.
(1) Earth dykes shall be constructed along each side
of the pavement and across the pavement at intervals,governed by
the rate of grade.. In placing earth no teams or wheelbarrows shall
be allowed on the concrete..
The earth dykes shall be built sufficiently high so as
to hold at least two (2) inches of water over the crown of the
pavement:
The basins formed by the above dykes shall be flooded
with water immediately after they are built and shall be kept
flooded for a period of fourteen (14) days, to the depth above
specified.
(2) Earth Blanket. The whole surface of the pavement
shall be covered with earth or sand to a depth of not less than
two (2) inches. The covering of earth or sand shall be kept
thoroughly and constantly wet by sprinkling with water for a
period of fourteen (14) days after the earth blanket has been
placed on the pavement.
The earth blanket shall be sprinkled with water not less
than three (3) times daily during the fourteen (14) day period
above specified.
All dyking, covering and watering must be commenced
not later than the morning of the next day after the pavement is
laid and must be completed by noon of that day...
• Such intersections as the Street Superintendent may
direct shall be opened to traffic after forty —eight (48) hours after
laying.. The.intersection shall be protected by planking which
shall have at least four (4). inches of earth between it and the
pavement. The planks shill be securely fastened so asilot`tol,"
dangerous to traffic.
(3) A system of sprinklers may be installed, ' in such a
manner that all portions of the concrete that is being cured' ,I—
be kept wet at all times during the period of curing'.
Ic .t-ti
- ;r
(f) CLEANING: The Contractor shall thoroughly clean the
surface of the pavement by removing all earth, sweeping and washing
immediately after the expiration of the fourteen (14) day curing
• period above spedifled.
(g) TRAFFIC: No vehicular traffic shall be allowed on
the pavement until twent17- •eight (28) days after the placing of the
concrete used in constructing the pavement
(h) JOINT FILLER: The filler for all expansion and con-
traction joints shall consist of composition board made of two
layers of paper or felt and a *filler of asphalt or cfomposition board
made of fibre permeated.with asphalt. The thickness of the com-
position board shall be as hereinbefore specified or as 3..uwn
on plans. The quality of the asphalt shall be such that it will not
become soft in warm weather or brittle in cold weather. when it
is necessary to splice the joint filler it shall be laced or
clips•,' >d together in a workmanlike and effective mar.:,3r. when in
stora.: on the work, all joint material shall be laid flat on
plank.
