with concrete. Each layer shall not exceed 61, in depth and shall be rolled
with a roller acceptable to the Engineer, preferably sheeps foot type of
roller. The outside of the embankment shall be kept lower than the inside
during all stages of the work., and the surfaces maintained in condition for
adequate drainage. The use of mucky or spongy material which will not
consolidate under the roller will not be permitted.
The street shall be graded from gutter line.to gutter line to the proper
subgrade to permit the specified thickness of paving material being laid to
bring the finished surface of the paving to the lines and grades shown on the
plans. A templet cut to the cross sections shown in the plans shall be used
for finishing the subgrade. An approved mechanical device for cutting the
subgrade will be preferred to hand work. After the device for cutting the
subgrade has passed over the subgrade, all loose earth and rock shall be
removed frown the subgrade. If the subgrade is loose, it shall be consolidated
with hand tamps.
The subgrade shall be compacted in the same manner as earth embankments.
The compaction of earthwork shall be accomplished by any satisfactory
method or methods that will obtain the density hereinafter specified unless
a specific method is provided on the plans or in special provisions.
The density of the compacted material in each layer of earthwork, as
determined by A.A.S.H.O. Designation T- 147, shall be not less than ninety-
five per cent (95 %) of the maximum density obtained by the Standard r?ethod of
Test for the Compaction and Density of Soils, A.A.S.H.O. Designation T -991,
modified to use material passing a No. 4 Sieve. The moisture content of the
material being compacted throughout each entire layer shall be substantially
that of optimum moisture for the particular soil type. It shall be the
responsibility of the contractor to bring the moisture content throughout
each layer of earthwork to be compacted to substantially that of optimum
moisture by the addition of water or by aeration as it may be necessary to
increase or decrease moisture under the conditions encountered.
All compaction operations shall be under the direct supervision of the
Engineer, and these operations shall proceed in such sequence as he may direct.
Embankment material containing excess moisture shall be permitted to dry to
the proper consistency before being compacted. The contractor shall be
responsible for correctly applying the water to the soil, for correctly mixing

the water with the soil, manipulating the soil and the water to the proper
uniform mpisture content before beginning compaction, and finally compacting
the properly moistened embankment.material uniformly to the degree of com-
paction required in these specifications.
The contractor shall be responsible for the stability of all embankments
made under the contract until final acceptance of the work and shall bear the
expense of replacing any portions which may become displaced due to carelessness
or negligent work on the part of the contractor. If it is necessary to replace
embankment which, in the opinion of the Engineer, has been destroyed or damaged
because of inadequate design, payment for replacement shall be made at the unit
prices bid for various items involved.
1,7here trenches are excavated across or within the paved area for storm
sewers and utilities, they shall be backfilled and compacted in eight (8)
layers to the density outlined above from bottom to top.
No concrete or other material for pavement or for base of pavement shall
be deposited upon the subgrade until it is checked aid approved by the Engineer.
8. Storm Sewers - The contractor shall make the necessary excavations
for the construction of the storm sewers and drop inlets, and he shall perform
all the auxiliary work that may be required thereby.
He shall inform himself regarding the location of all water pipe, private
sewers, main sewers, drains, or other property located beneath the surface of
the ground, in advance of the work, and shall use every precaution to protect
same. In case any of the above mentioned-property is disturbed or damaged,
the contractor shall immediately repair same-at his own expense. In the event
it is necessary to move water mains or sewers, the contractor, if ordered to
make the change, will be paid force account.
All excavation shall be in open cut unless the Engineer gives permission
to tunnel and the depth of the trench will be taken as the "cut" given by the
Engineer and which shall represent the vertical distance from the invert of
the sewer to the top of the stake and the contractor shall dig the bell hole
and shape the bottom of the trench to properly receive the pipe. All earth
in trench shall be excavated to a width of one (1) foot greater than the out-
side diameter of the pipe to be laid therein though no trench shall be less
than two feet in width. All excavated material shall be placed upon the bank
so as to interfere with traffic and the adjoining business as little as
possible.
The grade of the sewer shall be obtained by the use of batter boards and
a top line, and the contractor will be required at an times where pipe laying
is in progress to maintain the top line for a distance covering at least three
stakes. The elevation of the top line shall be determined from the depth of
.cutting as given by the Engineer, and the contractor shall keep with each gang
r
i
SECTION IV
Page 4 -5
a man whose duty is to see that the top line is in place at all times. It
is not intended that this requirement shall make it necessary for the contractor
to keep a man especially for this purpose, but to provide a competent man to
be with each gang at all times, whose duty it shall be to attend to the placing
of the top line and the giving of the grades to the pipe layer.
Before each pipe is lowered into the trench, the bottom of the trench
shall be brought to a true subgrade, in order to give an even bearing through-
out the length of the pipe and the bell hole dug. In the event that the
subgrade is too low it shall be brought to the proper grade by filling in
with earth which shall be well tamped. It will not be permissible to raise
the pipe to grade by blocking under the bell.
Successive pieces of pipe shall be fitted on top of the bank in order
that no joints already made shall be disturbed or broken in tryin to fit the
pipe in the ditch. Any slight imperfections in the pipe that may have been
passed by the Engineer shall be turned to the top.
Before each joint of pipe is laid, a coat of mortar shall be placed in
the bottom and quarters of the socket of the preceding joint of such thickness
that will fill the annular space and make the inverts of the pipe flush. In
Joining the pipe, the spigot end shall be slipped into the top of the socket,
and when home allowed to settle into place.
The space between the spigot and the hub end of the pipe shall be entirely
filled with mortar. The mortar shall be applied with the hands protected with
rubber mittens if desired, and shall be thoroughly pressed in all around so as
to make a joint as nearly watertight as possible. The finished joint shall be
pointed with a neat and generous bevel made with the hands. The interior of
each joint shall be wiped clean of all projecting mortar. No lengths of pipe
shall be laid until the one preceding it shall have sufficient fine earth
filled and tamped around it to hold it securely in place. -If, after laying,
any joint is moved or disturbed as to cause any danger of leakage, the joint
shall be uncovered and repaired.
Each length of pipe shall be thoroughly cleaned with a swab or "rat"
after the joint is made so as to insure that no mortar is left in the sewer
after the work is completed. The swab or rat shall be pulled out frequently
to remove the accumulated mortar. 'Then work is discontinued on any line at
night, or for other reason, the end of the pipe shall be closed with a wooden
plug, which shall f it in the hub end of pipe,
The trench shall not be backfilled until the work contained therein has
been examined and approved by the Engineer.
The earth shall be filled in and tamed very carefully around each piece
of sewer pipe to prevent the joints from becoming loosened or broken and at
least eight (8) inches of hand filling shall be placed over all pipe. No loose
w
I y
SECTION IV
Page i4 -6
rock shall be thrown into the trench until two feet of earth,has been filled
over the pipe. The remainder of the trench may be filled with bulldozer or
scraper or such other method as the contractor may prefer, except where the

concrete surface and shall be filled with fresh concrete equal in specifications
to the initial pour.
All exposed concrete surfaces which have been in contact with
forms shall be robbed smooth with carborundum brick and water immediately after
removal of the forms. The walls shall be washed clean after rubbing. All
form marks of any kind shall be removed before the work is acceptable.
The exposed tops of all walls, floors, and other concrete
surfaces not deposited against forms, shall have, unless otherwise specified,
a top finish of sufficient thickness to obtain a smooth surface and not to
exceed one -half inch in thickness, of mortar mixed in the proportions of one
part by volume of cement and two parts by volume of screened sand. No more
water shall be used in mixing the mortar than is necessary to make a plastic
material. In no case shall water appear on the surface of the mortar after
screening or floating. The surface shall be screened to a true surface and
finished with a wood float and troweled smooth unless otherwise specified.
Excess water shall be drained away or otherwise removed. The final finish
with a steel trowel shall not be made until the cement has acquired its initial
set.. No more troweling shall be done than is necessary to obtain a smooth
surface. At the option of the Engineer, the top surface of walls and walks
may be finished with a wire brush and an edging tool, instead of a trowel.
Not more than thirty minutes shall elapse after placing concrete at any point
prior to applying the mortar finish.
(4) Curing - Concrete not protected by farm work shall be

and labor required except reinforcing steel which shall be paid for in
accordance with the price bid per pound in the proposal.
8. Pavement - The pavement to be placed shall be plain concrete
pavement of uniform thickness of eight inches except where noted. The cross -
section of the pavement shall be as shown on the detailed plans. Steel
reinforcing bars and expansion joints shall be installed as shown on plans.
(1) Forms - For the concrete slab or curb, commercial steel
forms shall be provided, which shall have a flat surface on top of at least
1 -3/4" wide. Steel plates in forms shall have a thickness of at least No. 10
gauge. The forms must be free from warp and have sufficient strength to hold
the line and grade. Iron pins or stakes shall be provided every five (5)
feet or oftener and the forms held exactly to the established line or grade.
Forms varying from a straight line, (drawn from end to end) more than 1/411 in
line and 1/8" grade shall be plainly marked and removed from the work by the
contractor. The centerline form shall have a steel keyway permanently attached
to the form. TTood keyways frill not be permitted.
The metal forms shall have a depth equal to the side thickness
of the pavement or integral curb. On street returns or curves, flexible steel
forms shall be furnished.
For limited amount of pavement or special work, it will be
permissible to use wood forms of 2 inch stock and depth equal to the pavement.
All forms shall be cleaned of dirt and concrete and oiled before being used
each time. Wood f orms shall not be used except by written permission of the
Engineer.
Forms shall be set at a sufficient distance in advance of the
point where concrete is being deposited. Forms in place gill be subject to
check and correction of line or grade at any time.
(2) Expansion Joints - Expansion joints shall be located where,
and as indicated on the plans. The average spacing shall be 300 feet between
joints. The joints shall be constructed in accordance with details as shown
on the plans. The dowel and sleeve or the lug type of joint will be used.

SECTION IV
Page 4 -11
width of the slab and are at right angles to the centerline of the pavement .
and perpendicular to the pavement surface. No finished joint shall deviate
more than one -half inch either way from a straight line. Unless prescribed
joints occur at the same place transverse construction joints shall be made
at the end of each days run or when an interruption of more than thirty
minutes occurs in the concrete operation. These joints shall be constructed
in accordance with details shown on the plans.
(3) Contraction Joints- The contractor shall construct
contraction joints at 18 foot intervals if gravel is used or at 25 foot
intervals if crushed rock is used as coarse aggregate. The contraction
joints may be of either the sawed or dummy groove type. The contractor
shall include all labor, materials and necessary incidentals required to
construct the joints into the unit price for the concrete pavement as
stipulated in the proposal.
(4) Placing of Concrete - Upon the approved subgrade, the
concrete shall be placed after having been mixed as specified. Trucks used
shall be equipped with oversize tires on the rear wheels with a minimum width
of four (4) inches. If a mixer with a traction drive is used, and the wheels
or caterpillar tread cut up the subgrade, it must be carried on timbers. All
hauling or traffic shall be distributed aver full width of subgrade so far as
practicable in order to maintain a uniformly compacted condition.
Before any concrete is placed, the subgrade if dry, shall be
thoroughly wet down the night before and lightly sprinkled with water so long
as it will be absorbed, in advance of placing of concrete. No pools shall be
left on the subgrade.
After mixing, the concrete shall be rapidly deposited on the
subgrade, to the required depth and for the entire width of the pavement in
successive batches and in a continuous operation without the use of intermediate
forms or bulkheads between expansion joints. The concrete shall be placed in
one course. The concrete shall not be piled up and shoveled to place but
shall be dumped as near as possible to its final position, and shall be
thoroughly worked and tamped while being shaped up.
Care shall be taken in placing the concrete against bulkheads
at expansion joints and curbs and gutters not to rake coarse aggregate only
into such places. It shall be preferred that concrete shall be carefully
deposited at the edges by shovels. As soon as the concrete has been brought
to the proper thickness, the concrete along the edges shall be carefully
spaded and tamped. The use of interval vibrators may be used if approved by
the Engineer. The vibrator shall have 3200 pulsations per minute.
In case of a breakdown of the mixer, it will be permissible to
mix sufficient concrete by hand to complete the section or an intermediate
transverse joint as may be indicated by the Engineer, placed as hereinbefore
3 •
SECTION IV
Page 4 -12
specified at the point of stopping work. The maximum batch mixed by hand
shall not exceed one -half cubic yard. Any concrete in excess of that needed
to complete a section at the stopping of work shall not be used in the work.
Concreting shall cease when the descending air temperature
falls below 40 degrees F. It may be resumed when the ascending air temperature
rises to 35 degrees F. and will keep rising to a level above 40 degrees F.
In no case shall concrete be deposited on a frozen.subgrade nor shall frozen
materials be used in concrete.
(5) Finishing - The pavement shall be struck off and consolidated
with a mechanical finishing machine. The concrete shall be struck off at such
a height that after consolidation and final finishing it shall be at the exact
elevation and have the exact crown as shown on the plans. A depth of at least
2 inches of concrete shall be carried in front of the strike -off screed for
the full width of the slab, whenever the screed is being used to strike off
the pavement. The finishing machine shall be provided with a screed which
will consolidate the concrete by pressure. The concrete shall, through the
use of this machine, be brought to a true and even surface, free from rock
pockets, with the fewest possible number of passages of the machine. Hand
finishing tools shall be kept available for use in case the finishing machine
breaks down.
If hand finishing is used, the concrete shall be struck off and
consolidated, by means of a metal shod screed, to the crown and cross - section
shown on the plans and to such an elevation above grade that when consolidated
and finished, the surface of the pavement will be at the required elevation.
The screed shall be moved forward with a combined longitudinal and transverse
motion moving always in the direction in which work is progressing and so
manipulated that neither end is raised from the side forms during the strike -
off process.
(6) Floating - After the concrete has been struck off and
consolidated it shall be floated with a hand operated longitudinal float not
less than twelve feet in length and six inches in width, properly stiffened
to prevent flexibility and warping. In this operation, the longitudinal float,
operated from foot bridges resting on the side forms and spanning but not
touching the concrete, shall be worked with a sawing motion while held in a
floating position parallel to the road centerline and passing gradual from
one side of the pavement to the other. Iovement ahead along the centerline
of the pavement shall be in successive advances of not more than two - thirds the
length of the float. Any excess water or soupy material shall be L,rasted over
the sides of the forms in each pass. In the event that the cross - section is
not to grade after the longitudinal floating work shall be screeded again to
obtain the true section.
SECTION IV
Page 4 -1,3
(7) Straightedging - rester the longitudinal floating has been
completed and the excess water removed the surface shall be tested for trueness
with a straightedge not less than ten feet in length. Any depressions found
shall be immediately filled with fresh concrete, struck off, and refinished.
High areas shall be cut down and refinished.
(8) Belting - After the straightedging and after most of the
water sheen has disappeared.and just before the concrete becomes non - plastic,
the surface shall be belted with a 2 -ply canvas belt having a width of not
less than six inches and a length at least two feet greater than the width
of the pavement. The belt shall be operated with short strokes transverse
to the road centerline and with a rapid advance parallel to the road centerline.
(9) Curing - The pavement may be cured by the burlap, waterproof
paper, or wetted earth method at the choice of the contractor. As soon after
the final finishing operations as the concrete has set sufficiently, in the
judgment of the Engineer, to prevent marring of the surface, the top surface
of the pavement shall be covered by thoroughly wetted burlap. The strips of
burlap must be laid of overlap not less than six inches. The burlap shall be
kept thoroughly wet and shall remain in place until after the final set, or
in any case, not less than twenty -four hours after placement of the concrete.
The burlap shall be kept wet until just before placement of the final curing
agent. The use of worn burlap, burlap with holes, or burlap salvaged from
arq other use than concrete curing shall not be permitted. 'Jeight shall be
not less than one ounce per square foot.
(a). �rzetted Earth Method - As soon as the burlap has been
removed, the concrete shall be covered with not less than two inches of wetted
earth or sand, and shall be maintained at this thickness throughout the
process of curing. It shall be kept thoroughly saturated with water for three
days and thoroughly wetted down on the morning of the fourth day and shall
thereafter remain in place until permission has been given to open the pavement
to traffic. The period of curing shall be normally seven days (7), after which
the covering shall be removed and the pavement swept clean.
(b) Waterproofed Paper Method - After the burlap covering
has been removed, the concrete shall be wetted thoroughly and the entire
surface of the pavement slab shall be covered with paper of a type and quality
approved by the Engineer. It shall be strong and sufficiently tough to permit
its use under the conditions existing on highway ?,rork without being torn or
otherwise rendered unfit for the purpose during the curing operation. The
paper as prepared for use shall have such dimensions that a single unit will
extend from one bottom corner of the slab to the opposite bottom corner of a
slab of normal width with. allowance for shrinkage of the paper, and shall cover
a longitudinal distance on the slab of not less than'twenty feet. Paper not
manufactured in sizes which provide the dimensions specified above shall
be securely sewed or cemented together, the joints being securely sealed in
such manner that they do not open up or separate during the curing period.

and type of compound.
The curing compound shall be applied at the rate as
recommended by the manufacturer, and approved by the Engineer and in no case
more than 200 square feet per jallon. The compound shall be applied as soon
as possible after the concrete has been finished. The compound shall be
sprayed on in a manner that will produce a firm, continuous uniform moisture
impermeable film free from pinholes and shall adhere to the damp concrete
surface. The pavement after the compound has been applied shall be kept free
from any debris or pedestrian traffic for 24 hours or until the concrete has
completely set and become firm.
After the curing compound has been on the pavement for
24 hours or until, in the opinion of the Engineer, the concrete has a firm
set, it shall be covered with waterproof paper or wet burlap mats for 72 hours
or more, if, in the opinion of the Engineer, the concrete needs the protection
for a longer period of tine. The pavement shall be wetted down before the
placing of the paper or mats. The burlap mats shall be kept wet for,24 hours,
after they are laid in place. The paper or the burlap mats shall be lapped
sufficiently to prevent any area from becoming unprotected.
(10) Removal of Forms - Forms shall not be removed from
freshly placed concrete until it has set for at least twelve hours. They
shall be removed carefully, and in a manner to prevent damage to the edge
of the pavement.
(11) Payment - The price stipulated in the proposal per square
yard of concrete pavement shall include full compensation for furnishing all
labor, materials, tools, and equipment and doing: all the work involved in
constructing the pavement complete in place as specified, including the
joints and dowels and all appurtenances.
CA Curb - The curb shall be an integral curb of the cross - section
and dimensions as shown on detailed plans, and shall be constructed immediately
after the concrete pavement slab has been poured and finished. It shall be
applied before the concrete in the slab has taken its initial set so that a
firm bonding therewith may be obtained.
Ig
SECTION IV

The curb shall be formed to the exact dimensions shown on the plans
by use of steel templates made of 1/2 inch square steel bars and conforming
to the cross - section of the curb. After the slab has been finished, the
templates shall be firmly attached to the curb form at intervals not to
exceed 6 feet. They shall be removable. The concrete for the curb shall
be topped with cement grout and struck off by means of a longitudinal
straight -edge or screed working against the curb templates.
The back edge of curb shall be rounded with an edging tool having a
1/4 inch radiuse lifter forming and finishing the curb, templates shall be
removed and the curb shall be hand trowelled, where necessary, but care shall
be taken not to change the desired cross - section and shape of the curb by
over handling. Brush finish to conform T-ri.th the slab finish will be required.
Expansion and contraction joints shall be constructed in the curb
to coincide with the joints in the concrete slab. Three quarter inch redwood
or cypress wood filler shall be installed in the expansion joints. The edges
along the expansion joint shall be rounded with an edger of 1/4 inch radius.
One quarter inch joint material shall be placed in the curb above each
contraction joint in the pavement.
The concrete curb shall be depressed slightly at private driveways
and entrances. The amount of depression shall be dependent upon the location
and grades of the private driveways and entrances. The Enai.neer shall indicate
on the grade stakes the height of the curb at the driveways and entrances.

machinery and plant used must be maintained in satisfactory working condition.
(a) Sweeping and Cleaning - Immediately preceding the
tack coat application, the surface -to be treated shall be swept free of dust,
dirt and loose or foreign material. Such sweeping operations shall be
performed by mechanical methods, unless otherwise directed by special provi-
sions requiring hand labor. If deemed necessary by the Engineer, the surface
shall be sprinkled with water and given an additional sweeping with hand
brooms, it being the intent of these specifications that the surface to be
treated be as free as practical from dust, dust pockets, and layers or pockets
of other loose materials. The sweeping and cleaning operation shall be carried
only far enough in advance of the application of the bituminous material to
insure the surface being properly prepared at the time of the application.
(b) Application of Bituminous Material - After the surface
to be treated has been properly prepared in accordance with the specifications
outlined above, the bituminous material for the tack coat shall be sprayed

Any surplus of bituminous material forming in surface
depressions of the existing pavement shall be removed by hand sweeping; no
cover material shall be applied.
Following the application of the tack coat the street
shall be closed to allow the proper curing and penetration of the bituminous
material. -No bitumen shall be applied upon a surface containing surface
moisture or weather condition detrimental to the proper application of the
prime coat without specific authority of the Engineer. Special precautions
shall be observed to insure a uniform distribution of the bituminous material,
and the distributing machine shall be so adjusted and operated to evenly
distribute, at all times, the class of material being applied. Deposits of
the bituminous material upon the street surface in excess of the quantity
specified, caused by stopping or starting the distributing machine, by over-
flow, leakage, or otherwise, will not be permitted. The machine used for
distributing the bituminous material shall be required to maintain an operating
pressure of not less than 20 or more than 60 pounds per square inch, as directed
by the Engineer.
If the bituminous material shall break or be removed-from
any part of the surface prior to the application of the wearing course, such
areas shall be thoroughly cleaned and retreated with the prime coat material
before the wearing course is placed at the expense of the contractor.
(c) Checking Materials - Before the final estimate is
allowed, the contractor shall file with the Engineer, freight bills or other
documentary evidence as to quantity and origin of material used in the prime
coat.
(4) Method of Measurement - Bituminous material actually placed
at the direction -of the Engineer will be measured by the gallon and the number
of gallons will be determined by measurements of the distributor tank.

Total passing '200 sieve 75%
Fine sand shall not be accepted as mineral filler.
(4) Construction Methods - The methods employed in performing
the work and all equipment, tools, and plant machinery used in executing any
part of the work shall be subject to the approval of the Engineer before the
work is started. Whenever they are found unsatisfactory, they shall be changed
and improved as required by the Engineer. All equipment, tools, and plant
machinery must be maintained in a satisfactory working condition. The plant
used in the preparation of the mixture shall be approved by the Engineer.
(a) Preparation of Asphalt Cement - The asphalt cement
shall be heated at the paving plant to a temperature not exceeding-3000 F.
The penetration of the asphalt cement shall be maintained within the limits
of penetration specified throughout the period of use.
(b) Preparation of Mineral Aggregate - The coarse and
fine aggregate shall be dried and heated at the paving plant so that when
delivered to the mixer they shall be at as low a temperature as is consistent
with proper mixing and laying, and in no case to exceed 3500 F. Both may be
fed simultaneously into the same drier but in all cases, immediately after
heating, they shall be screened into three or more fractions and conveyed
into separate bins ready for batching and mixing with asphalt cement.
(c) Preparation of Plixture - Each size of hot aggregate
and the asphalt cement shall be measured separately and accurately in the
proportions in which they are to be mixed. The volume of mixture shall not
be so great as to extend above the tips of the miner blades when these blades
are in a vertical position. In batch mixing after the hot aggregate has been
charged into the mixer and thoroughly mixed the asphalt cement shall be
introduced in such manner as to spread evenly over the mixer, and the mixing
continued for a period of at least thirty (30) seconds, or longer if necessary
(l

to produce a homogeneous mixture, in which all particles of the mineral
aggregate are coated uniformly. In continuous mixing, the mixing period
shall not be less than thirty (30) seconds as determined by the formula
given in this Section, or longer if necessary, to produce a homogeneous
mixture.
The temperature of the mixture when discharged from the
mixer shall not be less than 2500 F. nor more than 3250 F.
(d) Transporting - The mixture shall be transported
from the paving plant to the work in tight vehicles previously cleaned of all
foreign materials and when directed by the Engineer, each load shall be
covered with canvas or other suitable material of sufficient size to protect
it from the weather conditions. No loads shall be sent out so late in the
day as to interfere with spreading and compacting the mixture during daylight
unless artificial light satisfactory to the Engineer is provided.
The mixture shall be delivered at a temperature of 2500 F.
to 3250 F. It shall be placed only upon a base which shows no evidence of
free moisture and only when weather conditions are suitable. The Engineer
may permit, however, work of this character to continue when overtaken by
sudden rains, to utilize materials which may be in transit from the plant at
that time, provided the mixture is within the temperature limits specified.
(e) Preparation of Base Prior to the arrival of the
mixture on the work the prepared base primed as specified shall be cleaned of
all loose and foreign materials.
Contact surfaces of curbing, gutters, manholes, and other
structures shall be painted -with a thin uniform coating of hot asphaltic
cement or asphaltic cement dissolved in. naphtha, just before the mixture is
placed against.them.
(f) Spreading and Finishing Unless otherwise permitted
by the Engineer the mixture shall be spread by means of a mechanical spreader
meeting the requirements given in Section 4, Paragraph D -2 and be spread in
courses and thicknesses as shown on the plans. Each course laid shall be
covered by the successive course not later than the following work day.
14hen hand spreading is permitted the work shall be done
in the following manner:
Upon arrival on the work, each load shall be unloaded
outside of the area on which it is to be spread upon suitable dumping platforms
and shall then be immediately distributed into place by means of hot shovels
and thoroughly combed with hot rakes into a uniformly loose layer of correct
depth. Care shall be exercised that workmen do not tread the mixture after
placing and before rolling.
SECTION IV
Page 4 -22
The process of uniformly distributing the surface course
mixture with rakes shall be so conducted that the prongs of the rakes shall
thoroughly and completely destroy any compaction which may have occurred in
transporting and placing the material. During the initial raking the prongs
of the rakes shall extend entirely through the surface course mixture to the
surface of the base, but care should be exercised not to destroy or loosen
the base material.
Immediately after the course is screened or raked and
before roller compaction is started the surface shall be checked, any
irregularities adjusted, all fat spots removed and replaced with satisfactory
material. Irregularities in alignment and grade along the outside edge shall
be corrected by the addition or removal of mixture before the edge is rolled.
The contractor shall provide and have on hand at all times
competent workmen who are capable of performing the work incidental to the
correction of all pavement irregularities or defects.
(g) Rolling — The mixture shall be compressed while in
a plastic condition and as soon after being spread as it will bear the weight
of the rollers without undue displacement.
Two types of rollers shall be used for obtaining compaction.
One shall be a seven to ten ton, self — propelled three wheeled roller and the
other shall be an eight to ten ton tandem roller. No roller will be permitted
on the work which is not in first class mechanical condition, free from backlash,
loose link motion, faulty steering mechanism or worn king bolts, and that
cannot be reversed smoothly. Each roller shall be in charge of a competent,
experienced roller operator, and must be kept in continuous operation as
nearly as practical. Ashes or drippings from the roller must not be allowed
to fall upon the bituminous surface. Rolling shall start longitudinally at
the sides and proceed toward the center of the roadway overlapping on
successive trips by at least one —half the width of the rear roller wheel.
The mixture shall then be subjected to diagonal rolling in two directions,
the second diagonal rolling crossing the lines of the first. The mixture
shall be continuously rolled until all roller marks are eliminated. The
motion of the roller shall at all times be slow enough to avoid displacement
of the mixture and any displacement occurring as a result of reversing the
direction of the roller or from any other cause shall be at once corrected
by the use of rakes and of fresh material where required. Rolling shall
proceed at an average rate of not to exceed two hundred square yards per
roller per hour, and shall continue until no further compression is possible.
To prevent adhesion of the mixture to the roller, the wheels shall be kept
properly moistened with a mixture of crater and oil, but an excess of such
moisture will not be permitted.

SECTION TO
Page 4 -23
Along curbs, headers, and similar structures.and all
places not accessible to the roller the mixture shall be thoroughly compacted
with hot tamers to produce sealed joints.
(h) Joints - The intent of this specification is to
secure a smooth tight and well sealed joint at the center, if mixture is laid
in one -half widths, and at any and all other places *There joints are required.
Placing of the surface course shall be as nearly continuous
as possible, and the full width of surfacing for each course completed at the
end of each day. 74hen the course is laid.in two or more layers the center
joint of successive layer shall be offset six inches.
The roller shall pass over the unprotected end of the
freshly.la.id mixture only when the laying of the course is discontinued for
such length of time'as to permit the mixture to become chilled. In all cases
provisions shall be made for proper bond with new surface course mixture by
cutting or trimming back the joint so as to expose an unsealed or granular
surface for the full specified depth of the course. At the end of each days
work,, joints shall be formed by laying and rolling against boards of 'the
thickness of the compacted mixture, placed across the entire -width of the.
surface course, or by other methods as may be approved by the Engineer. When
the laying of the surface course: mixture is resumed, the exposed edge of the
joint shall be painted with a thin coat of hot asphalt,cement or asphalt
cement thinned with naphtha, and the fresh mixture shall be raked against the
joint thoroughly tamped with hot tampers and rolled. Hot smoothing irons may
be used for sealing joints but in such cases extreme care shall be exercised
to avoid burning the surface.
(i) Surface Test - The finished surface shall show no
deviation of more than one- quarter inch from a template conforming to the
cross - section shown on the plans..-or more -than one - sixteenth inch per foot
deviation in the general surface as measured in the following manner.
A ten foot straightedge shall be placed parallel to the
centerline of the roadway so as to bridge any depressions . and -touch all high
spots. Ordinates measured from the face of the .straightedge to the surface
of the.pavement shall not exceed one - sixteenth inch for each foot in distance
from the nearer point of contact, with the further provision that the maximum
variation in ten feet shall not exceed one - quarter inch.
Such -portions of the finished surface course as are
defective in finish, density or composition, -or that do not comply in all
respects with the requirements of these specifications, shall be taken up,
removed and replaced with suitable material, properly mixed and laid in
accordance with these specifications and at the expense of the contractor.

except by permission of the Engineer, with the further provision that mixing
and placing operations shall be suspended when a descending air temperature
reaches 100 F. and held in abeyance until an ascending air temperature
reaches 350 F.
(5) Method of measurement - ?Fork completed and accepted will
be measured by the square yard, one and one -half (1 -1/2) inches thick complete
in place, and the measurements will include the amount actually placed and
accepted within the lines shown on the plans and typical cross- section, or as
