of work, and the increased work can fairly be classified under the specifications, such Increase shall be paid
according to the quantity actually done and at the unit price established for such work under this contract;

loss occasioned by such change, due to actual expenses incurred in preparation for the work as originally
planned.
24. EXTRA WORK

compensation to be paid to the Contractor for performing said extra work shall be determined by the following
methods:
Method (A) - By agreed unit prices; or

for the time actually employed or used on such extra work, plus actual transportation charges necessarily

(15%) of the actual field cost to be paid to Contractor shall cover and compensate him for his profit, overhead,

maintained primarily on account of such Extra Work, then the cost to maintain and operate the same shall be
Included in the "actual field cost."

any orders or Instructions appear to the Contractor to Involve extra work for which he should receive —
compensation or an adjustment in the construction time, he shall make written request to the Owners
Representative for a written order authorizing such extra work. Should a difference of opinion arise as to what
does or does not constitute extra work or as to the payment therefore, and the Owner's Representative insists
upon its performance, the Contractor shall proceed with the work after making written request for written order
and shall keep adequate and accurate account of the actual field cost thereof, as provided under Method (C).
The Contractor will thereby preserve the right to submit the matter of payment to arbitration as herein below
provided. ^

4. Apprentices and Trainees
a) Apprentices. Apprentices will be permitted to work at less than the predetermined rate
for the work they performed when they are employed pursuant to and individually
registered in a bonafide apprenticeship program registered with the U.S. Department of
Labor, Employment and Training Administration, Bureau of Apprenticeship and
Training, or with a state apprenticeship agency recognized by the Bureau, or if a person is
employed by his or her first 90 days of probationary employment as an apprentice in such
an apprenticeship program, who is not individually registered in the program, but who
has been certified by the Bureau of Apprenticeship and Training or a state apprenticeship
Page 4 of 7
City Transit Managemet,..ne; d.b.a. Citibus
FTA Requirements
►-07/03/97
agency (where appropriate) to be eligible for probationary employment as an apprentice.
The allowable ratios of apprentices to journeymen on the job site in any craft
classification shall not be greater than the ratio permitted to the contractor as to the entire
work force under the registered program. Any worker listed on a payroll at an apprentice
wage rate, who is not registered or otherwise employed as stated above, shall be paid not
less than the applicable wage rate on the wage determination for the classification of
work actually performed. In addition, any apprentice performing work on the job site in
excess of the ratio permitted under the registered program shall be paid not less than the
applicable wage rate on the wage determination for the work actually performed. Where
a contractor is performing construction on a project in a locality other than that in which
its program is registered, the ratios and wage rates (expressed in percentages of the
journeyman's hourly rate) specified in the contractor's or subcontractor's registered
program shall be observed. Every apprentice must be paid at not less than the rates
specified in the registered program for the apprentice's level of progress, expressed as a
percentage of the journeyman's hourly rate specified in the applicable wage
determination. Apprentices shall be paid fringe benefits in accordance with the
provisions of the apprenticeship program. If the apprenticeship program does not specify
fringe benefits, apprentices must be paid the full amount of fringe benefits listed on the
wage determination for the applicable classification. If the administrator determines that
the different practice prevails for the applicable apprentice classification, fringe benefits
sh& ba paid in accordance with that determination. In the event the Bureau of
Apprenticeship and Training, or a state apprenticeship agency recognized by the Bureau,
withdraws approval of an apprenticeship program, the contractor will no longer be
permitted to utilize apprentices at less than the applicable predetermined rate for the work
performed until an acceptable program is approved.
r"
b) Trainees. Except as provided in 29 CFR Section 5.16, trainees will not be permitted to
work at less than the predetermined rate for the work performed unless they are employed
pursuant to an individually registered in a program which has received prior approval,
evidenced by formal certification by the U.S. Department of Labor, Employment and
Training Administration. The ratio of trainees to journeyman on the site shall not be
greater than permitted under the plan approved by the Employment and Training
r
Administration. Every trainee must be paid at not less than the rate specified in the
approved program for the trainee's level of progress, expressed as a percentage of the
journeyman's hourly rate specified in the applicable wage determination. Trainees shall
�.,
be paid fringe benefits in accordance with the provisions of the trainee program. If the
trainee program does not mention fringe benefits, trainees shall be paid the full amount of
fringe benefits listed on the wage determination unless the Administrator of the Wage
and hour Division determines that there is an apprenticeship program associated with the
corresponding journeyman's wage rate on the wage determination for the classification of
work actually performed. In addition any trainee performing work on the job site in
excess of the ratio permitted under the registered program shall be paid not less than the
r
applicable wage rate on the wage determination for the work actually performed. In the
even the Employment and Training Administration withdraws approval of the training ..
program, the contractor will no longer be permitted to utilize apprentices at less than the
applicable predetermined rate for the work performed until an acceptable program is
approved.

5. Compliance with Copeland Act Requirements. The contractor shall comply with the
requirements of 18 U.S.C. 874 and 29 CFR Part 3, which are incorporated by reference. This
act provides that each contractor or subgrantee shall be prohibited from inducing, by any
means any person employed in the construction, completion, or repair of public work, to give
up any part of the compensation to which he is otherwise entitled.
6. Contract Termination: Debarment. A breach of the contract clauses in 29 CFR Section 5.5
may be grounds for termination of the contract, and for debarment as a contractor and a
subcontractor as provided in 29 CFR Section 5.12.
7. Compliance with Davis -Bacon and Related Act Requirements. All rulings and interpretations
of the Davis -Bacon and related acts contained in 29 CFR Parts 1, 3, and 5 are herein
incorporated by reference.
8. Disputes Concerning Labor Standards._ Disputes arising out of the general dispute clause of

for use on this work. Tests should be made approximately
20 days before beginning the concrete operation.
The contractor will submit in advance•of construction the
mix design and the result of compression tests made by a
commercial laboratory. These will be made on each type of
concrete mix design proposed for use on this project.
Tests shall be made on 6 cylinders for each mix, 3 tested
in 3 or 7 days, 3 tested at 7 or 28 days. Additional tests
shall be furnished if material source is changed or if
concrete used varies from the original design.
The Engineer shall approve the mix design after the pre -
construction tests have been completed.
Construction Tests
Tests of the aggregates and the concrete will be made by
the Engineer during construction to determine conformity
with the specifications. Test cylinders will be made in

costs of all such testing will be borne by the City but the
Contractor shall cooperate in securing and storing samples
and shall furnish all materials required for sampling.
A strength test shall consist of five standard test
cylinders made from a composite sample obtained in
accordance with the requirements of ASTM Designation C-172.
Two of the cylinders shall be tested at 3 or 7 days and at
7 or 28 days. The fifth cylinder shall be held available
for subsequent testing, if determined necessary by the
Engineer. The test result shall be the average of the two 7
or 28 day specimens, except that, if one specimen in the
test shows manifest evidence of improper sampling, molding,
or testing, it shall be discarded and the remaining two
strengths averaged. Should more than one specimen
representing a given test show definite defects, due to
improper sampling, molding or testing, the entire test
shall be discarded.
The result of the 7 or 28 day strength tests shall be used
as the basis for accepting or rejecting the concrete
represented.
The results of the 3 or 7 day strength tests will be
compared.with the 3 or 7 day strength of the
preconst,tuction test cylinders for the type and slump of
the concrete being produced. Should the 3 or 7 day
strengths indicate a deficiency in the 7 or 28 day
strengths, the Engineer may require a temporary change in
proportions to correct such deficiency. Such change shall
remain in effect until the 7 or 28 day strength of the
material in question is determined, at which time the
change shall become permanent or shall be rescinded,
depending upon the results of the 7 or 28 day test.

temperature is above 40° F and rising.
The engineer may use his discretion to require a cover over
the asphaltic mixture when being hauled from the plant to
�- the job site. The air temperature shall be taken in the
shade away from artificial heat or as reported by the
National Weather Service .on their hourly report (Telephone
No. 762-0141). It is further provided that the prime coat,
r tack coat or asphalt stabilized base shall be placed only
when the general weather conditions and temperature and
moisture conditions of the subbase or subgrade,in the
r` opinion of the Engineer, are suitable.
If, after being discharged from the mixer and prior to
placing, the temperature of the asphaltic mixture is 259 F
or more below the temperature approved by the Engineer, all
IV-23
or any part of the load may be rejected and payment will
not be made for the rejected material.
(2) Prime Coat
The prime coat shall consist of an application of 0.25
gallons per square yard of MC asphalt. The asphalt
stabilized base shall not be applied on a previously primed
course until the prime coat has completely cured to the
satisfaction of the Engineer.
(3) Tack Coat.
Before the asphaltic mixture is laid, the surface upon
which the tack coat is to be placed shall be cleaned
thoroughly to the satisfaction of the Engineer. The surface
shall be given a uniform application of tack coat using
asphaltic materials of this specification. This tack coat
shall be applied) as directed by the Engineer, with an
approved sprayer at a rate not to exceed 0.10 gallon per
square yard of surface. Where the mixture will adhere to
the surface on which it is to be placed without the use of
a tack coat, the tack coat may be eliminated by the
Engineer. All contact surfaces of curbs and structures and
all joints shall be painted with a thin uniform coat of the
asphaltic material meeting the requirements for tack coat.
The tack coat shall be rolled with a pneumatic tire roller
when directed by the Engineer.
(4) Transporting
The asphaltic mixture, prepared as specified above shall be
hauled to the work in tight vehicles previously cleaned of
all foreign material. -The dispatching of the vehicles shall
be arranged so that all material delivered may be placed,
and all rolling shall be completed during daylight hours.
The inside of the truck body may be given a light coat of
Oil,' lime slurry or other material satisfactory to the
Engineer, if necessary, to prevent mixture from adhering to
the body. In cool weather or for long hauls, canvas covers
and insulating of truck bodies may be required. Vehicles of
the semi -trailer type are prohibited.
(5) Placing
Generally, the asphaltic mixture shall be dumped and spread
on the approved prepared surface with the specified
spreading and finishing machine, in such a manner that when
properly compacted, the finished course
uniform density, and will conform with
shown on the plans and to the lines and
IV-24
will be smooth, of
the typical sections
grades established
I
by the Engineer. During the application of asphaltic
PM 7 -
material, care shall be taken to prevent splattering of
adjacent pavement, curb and gutter and structures.
The mixture shall be spread and compacted in layers or
lifts as specified on the plans or as directed by the
Engineer. The sequence of compacting shall be such that
undue displacement of the edge of the course does not
occur. On deep lifts, the edge of the course may be rolled
with a motor grader wheel or similar equipment or supported
by blading a roll of earth against the edge of the course
�^
prior to compacting the surface.
When the asphaltic mixture is placed in,a narrow strip
�.
along the edge of an existing pavement, or used to level up
small areas of an existing pavement or placed in small
i
irregular areas where the use of a finishing machine is not
practical, the finishing machine may be eliminated when
authorized by the Engineer, provided a satisfactory surface
can be obtained by other approved methods.
I. Compacting
(1) As directed by the Engineer, the asphalt stabilized
base shall be compacted thoroughly and uniformly with
the 'specified rollers. In lieu of the rolling equipment
specified, the Contractor may, upon written permission
from the Engineer, operate other compacting equipment
that will produce equivalent relative compaction as the
specified equipment. If the substituted compaction
equipment fails to produce the desired compaction as
would be expected of the specified equipment, as
determined by the Engineer, its use shall be
discontinued. When directed by the Engineer, the
initial compaction shall be accomplished with pneumatic
r tire rollers.
(2) When rolling with the three wheel, tandem, or vibratory
r'
rollers, rolling shall start longitudinally at the
sides and proceed toward the center of the pavement,
overlapping on successive trips by at least half the
�.
width of the rear wheel unless otherwise directed by
the Engineer. Alternate trips of the roller shall be
slightly different in length. On super -elevated
curves, rolling shall begin at the low side and
progress toward the high side unless otherwise directed
by the 'Engineer. When rolling with vibratory steel
wheel rollers, the manufacturer's recommendation shall
be followed unless directed otherwise by the Engineer.
Rolling with pneumatic -tire roller shall be done as -
directed by the Engineer. Rolling shall be continued
IV-25
r
f .
a
.until no further increase in density can be obtained
and all roller marks are eliminated. The motion of the
roller shall be slow enough at all times to avoid
displacement of the mixture. If any displacement
occurs, it shall be corrected at once by the use of a
rake, and of fresh mixtures where required. The roller
shall not be allowed to stand on any portion of the —
pavement mixture which has not been fully compacted.
To prevent adhesion of the mixture to the roller, the
wheels shall be kept thoroughly moistened with water, —
but an excess of water will not be permitted. All
rollers must be in good mechanical condition.
Necessary precautions shall be taken to prevent the
dropping of gasoline, oil, grease or other foreign -
matter on the roadway, either when the rollers are in
operation or when standing.
Hand Tampin
The edges of the pavement along curbs, headers and
similar structures, -and all places not accessible to
the roller, or in such positions as will not allow
thorough compaction with the rollers, shall be
thoroughly compacted.with lightly oiled tamps. —
J. Surface Finish
The compacted material shall conform to the typical cross
sections, lines and grades as shown on plans and directed
by the Engineer and shall have a smooth surface with a
reasonably uniform texture acceptable to the Engineer.
Unacceptable finished surfaces may be corrected by the
placement of additional mixture, all at the expense of the
Contractor.
K. Protection Of The Work And Opening To Traffic
The completed asphalt stabilized base course shall be
opened to traffic as provided by the plans and as directed
by the Engineer. All construction traffic allowed on the
base course shall comply with the State laws governing
traffic on highways unless otherwise authorized by the
Engineer. When another roadway surface is provided for the
traveling public and construction traffic through the
project, the Engineer may prohibit traffic on the completed
base course.
L. Surface Density Test
IV-26

City personnel will provide density test and results
r - throughout the construction process at no cost to the
E contractor.
Samples of the completed pavement shall be removed from
locations designated by the Engineer to enable him to
determine the composition, compaction, and density of the
pavement. Samples for each day or fraction thereof shall
be taken by City personnel. The contractor shall replace
the pavement removed from core holes at no cost to the
City. If the pavement is deficient in composition,
compaction, or thickness, satisfactory correction shall be

If the laboratory stability and/or field tests of the
mixture produced has'a value lower than that specified, and
in the opinion of the Engineer is not due to change in
source or quality of materials, production may proceed, and
the mix shall be changed until the laboratory/field tests
equals or exceeds the specified values. If there is, in the
opinion of the Engineer, an apparent change in any material
from that used in the design mixtures, production will be
discontinued until a new design mixture is determined by
trial mixes.
11. SILO STORAGE
A silo storage system may be used during the normal day's
operation. The mixture coming out of the silo storage must be
of equal quality and temperature to that coming out of the
mixing plant. Any operation that has tendency to segregate
the mixture or fails to maintain a thorough and uniform
mixture and temperature shall not be used. If any load of
mixture coming out of the silo storage system fails to meet
the asphalt specifications or gradation requirements, then
the total contents of the silo storage system shall be
condemned.
12. BARRICADES AND SIGNS
Barricades shall be constructed of clean, sound lumber, shall
be of first-class workmanship,' and all surfaces above ground
shall be painted with an approved brand of'white paint to
secure thorough coverage and a uniform white color. In no
case shall less than two coats be used. The paint for
barricade stripes shall be reflective orange and reflective
white. All dimensions, striping, lighting, painting, coloring

be removed immediately when those conditions cease to exist
IV-34`
r+
or the restrictions are witdrawn• Guide signs directing
traffic to and on temporary routes or detours shall be
removed when no longer applicable.
Standardization is important with respect to design and
placement, and uniformity of application is equally
important. Identical conditions should always be marked with
the same type of sign, irrespective of where those particular
conditions occur.
All signs that are to convey their message during hours of
darkness shall be reflectorized or illuminated. Signs for
daytime use only may be non-reflectorized but a fluorescent
background material will be used for increased daytime
visibility if requested by the Engineer.
Where there is serious interference from extraneous light
sources, and a reflectorized sign is not likely to be
effective, an illuminated sign will be used.
Construction warning signs shall have a black legend on an
orange background and shall conform to the standards as to
size, shape and color as outlined in the Texas Manual on
UNIFORM TRAFFIC CONTROL DEVICES mentioned above.
r' Barricades, flares, and signs are a necessity in the
construction involved in this contract. The provision of
these items by the Contractor should be considered in the bid
prices submitted, as no separate compensation will be made,
unless indicated otherwise. in the plans or the proposal.
No work will be permitted on any project prior to
installation of barricades or other warning devices at the
beginning and end of the construction area.

Details of Construction
1. CONCRETE
A. Curb and Gutter (Class A -Concrete)
Description
This item shall consist of Portland Cement 24" concrete
curb and gutter or 24" separate gutter as shown on the
plans or as directed by the engineer, and shall be
constructed of Class A concrete. Included in the curb and
gutter item is the subgrade preparation and the filling
and shaping of the area behind the curb.
1. Curb Openings
Separate gutter sections will be placed only across alleys
and driveways presently in use or where definitely planned
for future property improvements. It shall be the
responsibility of the contractor to contact the property
owner and determine the proper location of driveways
before curb and gutter is constructed. All gutters across
new or proposed driveways must meet therequirements set
forth-.ib the City Sidewalk and Driveway Regulations,
Ordinance Number 1466 and amendments thereto and gutters
across existing driveways will be required to conform to
said regulations if no hardship to the existing property
improvements is'involved. In any event, all curb and
gutter to be poured must have the engineer's approval as
to driveway widths and location, in addition to the
section, and line and grade approval before any pour is
started on any curb and gutter unit.
2. Excavation and Subarading (See Section V-2)
Excavation for the curb and gutter shall be made with the
excavation of the entire street. The excavation shall be
done to,the lines and grades set by the engineer and in
such a manner as to require a maximum /2" (inch) of fill
to bring the subgrade to the correct elevation. Subgrade
that is undercut 1" (one inch) or more shall be brought to
the correct elevation by scarifying, wetting, disking,
blading, rolling and compacting to 95% Standard Proctor
Density (A.S.T.M. D-698) with pneumatic rolling to correct
elevation prior to setting forms. Before completion of
curb and gutter, all traffic signs and street name markers
found in the way of paving will immediately be relocated
behind the proposed curb and gutter by the Contractor. *"
V-1
r
{
3._ Setting Forms
Forms for concrete and gutter shall be set to the lines
and grades established by the engineer after the subgrade
has been prepared. The forms shall be held together and in
place in such a manner that they will not move during the
placing and working of the concrete. The forms shall be
cleaned and oiled prior to pouring concrete. Face forms
and construction joints (removable metal plates) shall be
set to hold the concrete for the curb in place until it is
to be finished.
Forms for--radii'shill be set in'the same manner as the
straight -forms except that no face form will be required
if a true section is obtained by other methods. The radii
forms shall be set in such a manner that they -curve will be
true.
4. Placement (Including Making Joints)
Sufficient concrete shall be placed to allow for shrinkage
and extra material for finishing, and the :concrete shall
be floated and troweled to the approximate section, and
only after the concrete receives'a partial set shall the
face forms be removed. The section shall then be shaped to
the true cross-section by the use of a metal -screed which
is shaped to the true cross-section.
A "mule" screed shall be used only to shape to true cross-
section when topping material is provided and pushed along
on the front edge of the mule.
Curb and gutter shall be constructed with an expansion
joint at the tangent point of each return at intersections
and at intervals of no more than forty (40) feet between
the intersections. Forty feet intervals may be waived if
curb and gutter machine is used. Expansion joints shall be
of the material hereinbefore specified. Construction
;joints formed by removable metal plates (templates)
accurately shaped to the cross-section of the curb and
gutter shall be located at the mid -point of each section
between expansion joints or as directed by the engineer.
Contraction joints shall be placed at ten foot intervals.
All joints shall be perpendicular to the surface of the
concrete and to the axis of the section..
5. Finishing..
A ten (10) foot metal "straight -edge" shall be used to
"strike the flow line to grade, continuously along the flow
line of the, gutter. This operation shall be followed with
V-2
a four (4) foot spirit levelto.assure the continuous
grade down the flow -line the length of the gutter.
Curb and gutter shall be finished uniformly by wood
trowelling to an accurate cross-section. Extra water will
not be added for finishing. The final finish will be
accomplished with a brush, the last stroke being one from
the back of curb to the lip of gutter. Both sides of all
r joints, the lip of gutter, and the back edge of the curb
shall be finished with a 1/4" radius edging tool before
the final brushing. Curves at the top and bottom of the
section shall present a uniform appearance without "waves"
L in the face of the curb or "pockets" in the gutter.
Concrete shall not be poured during sand storms. Concrete
shall be protected to maintain temperature of not less
than 50 degrees F. for five days after placement. If
aggregate and water are heated, they shall not be heated
above 90 degrees F. Concrete shall not be placed when the
ambient temperature is less than 40 degrees F. It shall be
the responsibility of the Contractor to anticipate as
nearly as possible changes in weather conditions which
would affect the placement and protection of the concrete,
and be prepared to protect freshly placed concrete when
sudden changes in the weather make such protection
necessary.
6. Removing Forms
Special care is required of the Contractor in his removing
of pins and of forms. Pins shall be pulled from the ground
to free forms. If hammering is found to be necessary, a
light, one (1) pound hammer shall be used. The contractor
shall not place forms or pins on newly finished concrete.
Loading and unloading of forms from a truck shall be
executed by two workmen. It is the duty of the Contractor
to remove any warped forms found in any section of forms,
before it is poured. When forms are pointed out as
defective, those forms shall then be removed from the job
site and not returned until they have been inspected by
the Engineer.
7. Machine Laid Curb and Gutter
Class A concrete shall be used for machine laid curb and
�^ gutter. The slump of the concrete shall be as directed by
the Engineer. Reinforcing steel, if required, shall
conform to Section 3 under Materials of Construction.
The curb and gutter shall be laid by an extrusion machine
approved by the Engineer. Immediately prior to placing the
V-3
curb and gutter, the previously approved foundation- 'shall '^
be thoroughly cleaned.'
The line for top of curb shall be maintained from a
guideline set by the Contractor from survey marks
established by the Engineer. Curb outline shall strictly
conform to the details shown on the plans.
The approved mix shall be fed into the machine in such a
manner and at such consistency that the finished curb will
present a well compacted mass with a surface free from
voids and honeycombs and true to established shape, line,
and grade.
Additional surface finishing shall be performed
immediately after extrusion. Extra water -will not be added
for finishing Unless otherwise specified by the Engineer,
joints shall be constructed as follows; Expansion joints
shall be located at each end radius at intersections and
alley returns and at the beginning,of the pour, and dummy
grooved joints shall be spaced at 10 foot intervals --
between the expansion joints.
8. Curincr
All concrete work shall be covered with heavy water -proof
type paper to prevent loss of moisture and to prevent

contact with .the ,side.forms-.
vibrators shall be operated i
interfere with the transverse
Mechanically operated
n such a manner as to not
or longitudinal joints.
Separate vibratory units shall be operated at sufficiently
close intervals to provide uniform vibration and
consolidation to the entire width of the pavement. The
frequency in air of the internal spud type vibratory units
shall be not less, than 8,000 cycles per minute and not
less than 5,000 cycles per minute for tube types and the
method of operation shall be as directed by the Engineer.
The Contractor shall have -a satisfactory tachometer
available for checking the vibratory elements.
The pavement vibrators shall not be used to level or
spread the concrete but shall be used only for purposes of
consolidation. The vibrators will not be operated where
the surface of the concrete, as. spread, is below the
elevation of the finished surface of the pavement, except
for the first lift of concrete where the double strike off
method of placement is employed, and the vibrators shall
not be operated for more than 15 seconds while the machine
upon which they are installed is standing still.
Approved hand manipulated mechanical vibrators shall be
furnfAed in the number required for provision of proper
consolidation of the concrete along forms, at joints and
in areas not covered by mechanically controlled vibrators.
These vibrators shall be sufficiently rigid to insure
control of the operation position of the vibrating head.
Complete and satisfactory consolidation of the concrete
pavement is a most important requirement of this
specification. Cores taken shall be carefully examined for
voids, honeycombing or other evidence of. incomplete
consolidation. If such evidence is present, changes in the
consolidation procedures and/or equipment will be made to
insure satisfactory consolidation.
Finishin
Machine-Fininshing. All concrete pavement shall be
finished mechanically with approved power -driven machines,
except as herein provided. Hand -finishing will be
permitted on the transition from a crowned section to a
superelevated section without crown or curves, and on
straight line superelevation sections less than 300 feet
in length. Hand -finishing will also be permitted on that
portion of a widened pavement outside the normal pavement
width, on sections where the pavement width is not
V-14
uniform, or required monolithic widths are greater than
r - that of available finishing machines.
Machine -finishing of pavement shall include the use of
power -driven spreaders, power -driven vibrators, power -
driven transverse strike -off, and screed, or such
i4 alternate equipment as may be substituted and approved by
the Engineer.
All concrete shall be consolidated by a mechanical
vibrator. As soon as the concrete has been spread between
the forms, the approved mechanical vibrator shall be
operated to consolidate the concrete and remove all
voids. Hand -manipulated vibrators shall be used for areas
not covered by the mechanical vibratory unit.
The transverse finishing machine shall first be operated
to compact and finish the pavement to the required section
and grade, without surface voids. The machine. shall be
operated over each area as many times and at such
intervals as directed. At least two trips will be required
and the last trip over a given area shall be a continuous
run of not less than 40 feet. After completion of
i finishing with the transverse finishing machine a
transverse drag float may be used.
The consistency of the concrete as placed should allow the
completion of all finishing operations without the
addition of water to the surface. When field conditions
are such that additional moisture is needed for the final
concrete surface finishing operation, the required water
shall be applied to the surface by fog spray only and
shall be held to a minimum.
After finishing is complete and the concrete still
workable, the surface shall be tested for trueness with an
approved 10-foot steel straightedge. The straightedge
shall be operated from the side of the pavement, placed
parallel to the pavement centerline and passed across. the
slab to"reveal any high spots or depression. The
straightedge shall be advanced along the pavement in
successive stages of not more than one-half its length.
Practically perfect contact of the straightedge with the
surface will be required, and the pavement shall be
leveled to this condition, in order to insure conformity
with the surface test required below, after the pavement
has fully hardened. Any correction of the surface required
shall be accomplished by adding concrete if required and
by operating the longitudinal float over the area. The .
surface test with the straightedge shall then be repeated.
V-15
r
For one --lane pavement placement and uniform widening, the
equipment for machine -finishing of concrete pavement shall
be as directed by the Engineer but shall not exceed the
requirements of these specifications.
After completion of the straightedge operation, as soon as
construction operations permit, texture shall be applied
with 1/8-inch wide metal tines with clear spacing between
the tines being not less than 1/4 inch nor more than 1/2
inch. If approved by the Engineer, other equipment and
methods may be used, provided that a surface texture
meeting the specified requirements is obtained. The
texture shall be applied transversely. It is the intent
that the average texture depth resulting from the number
of tests directed by the Engineer be not less than 0.060
inch with a minimum texture depth of 0.050 inch for any
one test when tested in accordance with Test Method Tex-
436-A. Should the texture depth fall below that intended,
the finishing procedures shall be revised to -produce the
desired texture.
12.. Proportioning of concrete
Concrete shall be composed of Portland cement, fine
aggregate, coarse aggregate, mineral filler and/or
admixture if used and water, mixed in proportions as
approved by the Engineer in the mix design as submitted by
a commercial laboratory and in the manner set forth in
this specification. On the basis of job and laboratory
investigationsofthe proposed materials; the Engineer
will fix the proportions by weight of water, coarse
aggregate, fine aggregate, cement, -admixture and mineral
filler where required, in order to produce concrete of the
specified strength and workability.
13. Concrete Strength
The concrete mix will be designed with the intention of
producing a minimum average flexural strength (Modulus of
rupture)' of 600 pounds per square inch and compressive
strength of 3000 psi at 7 days and/or a 28 day compressive
strength of 3,600 pounds. per square inch. The coarse
aggregate factor (dry, loose volume of coarse aggregate
per unit volume of concrete) shall riot exceed 0.85. Unless
otherwise shown on plans the concrete shall contain not
less than six sacks of cement per cubic yard of concrete.
The water -cement ratio (net gallons of water per sack of
94 1 pound cement) shall not exceed 6.0 gallon/sack.
Concrete specimens shall be prepared, cured and tested as
outlined in THD Bulletin c-11.

14. Workability of Concrete
r =
` Concrete shall be uniformly plastic, cohesive and
` workable. Workable concrete is defined as concrete which
can be placed without honeycomb and without voids in the
surface of the pavement. Workability shall be obtained
l without producing a condition such that free water appears
on the surface of the slab when being finished as
specified. Where water appears on the surface of the
concrete after finishing and this condition cannot be
corrected by reasonable adjustment in the batch design,
the bleeding will be immediately corrected by one of the
following measures or a combination of two or more of the
` following listed measures:
a. Redesign of the batch
b. Addition of mineral filler to fine aggregate
C. Increase of cement content
In the event that the measures taken do not eliminate the
bleeding immediately, concrete placement operations will
be suspended, as directed by the Engineer, and will remain
suspended, until such time as additional trial mixes
T demonstVate that a non -bleeding batch design has been
1 achieved. Failing to achieve a satisfactory laboratory
batch design the Contractor will be required to use
different materials and to submit samples thereof for
additional trial mixes and pilot beams as specified in THD
Bulletin C-11.

Prior to the beginning of the concrete placement, and
thereafter before any change in source or characteristics
of any of the ingredients except mineral filler,
sufficient compression tests using various quantities'of
cement and aggregates proposed for use shall be supplied
the Engineer for consideration.
Mixes will be designed and made in sufficient number to
represent a wide range of water -cement ratios. These mixes
shall comply with the requirements herein prescribed for
workability. From these preliminary tests the water -cement
ratio required to produce concrete of the specified
V-17
r-
strength will be selected by -the Engineer. The Contractor
may at any time present in writing a suggested mix design
and the Engineer will make the tests necessary to
determine its acceptability under these specification
requirements.
For mixing the concrete to be used in making the
preliminary test specimens, the Contractor shall furnish
and operate the mixer approved for use on this project. A
minimum one cubic yard.batch shall be mixed or a batch of
sufficient size to afford proper mixing, whichever is the
greater. In lieu of the above mixer and procedure, the
Contractor may furnish a portable mixer of sufficient
rated capacity to mix a minimum three -sack batch; in which
case, the batch mixed for the preliminary test shall not
be less than the rated capacity of the mixer furnished.
No additional compensation will be allowed for equipment,
materials or labor involved in making preliminary test
specimens.
After the mix proportions and water -cement ratio required
to produce concrete of the specified strength have been
determined, placing of the concrete may be started.
Type I`cement shall have a specified surface area within a
range of 1,600 to 1,900 square centimeters per gram. A
change in the specific surface of the cement of more than
100 square centimeters per gram may require a new mix
design.
16. Subcgrade and Forms
Preparation of subgrade.
Rolling and sprinkling shall be performed when and to the
extent directed, and the roadbed shall be completed to or
above the plane of the typical sections shown on the plans
and the lines and grades established by the Engineer.
Drainage of the roadbed shall be maintained at all times.
Sealed or treated subgrade cut in the preparation of the
subgrade or_setting of pavement forms shall be .resealed or
the subgrade restored to the original conditions as
directed by the Engineer. See Section V-2.
The subgrade shall be maintained in a smooth, compacted
condition in conformity with the required section and
established grade until the pavement is placed and shall
be kept thoroughly wetted down sufficiently in advance of
placing any pavement to insure its being in a firm and
V-18'
moist condition for at least 2 inches below the prepared
_ surface. Sufficient subgrade shall always be prepared in
advance to insure satisfactory prosecution of the work. No
equipment or hauling shall be permitted on the prepared
subgrade, except by special permission of the Engineer,
rwhich will be granted only in exceptional cases and only
where suitable protection in the form of two-ply timber
mats or other approved material is provided.
r
17. Placing and Removing Forms
The subgrade under the forms shall be firm and cut true to
grade so that each form section when placed will be firmly
in contact for its whole length and base width, and
exactly at the established grade. Forms shall be staked
with at least three pins for each 10-foot section. A pin
shall be placed at each side of every joint. Form sections
shall be tightly joined and keyed to prevent relative
displacement. Forms shall be cleaned and oiled each time
they are.used.
Forms shall be set for a sufficient distance in advance of
the point where concrete is being placed to permit a
finished and approved subgrade length of not less than •300
feet ahead of the mixing. Conformity of the grade and
alignment of forms shall be checked immediately prior to
placing concrete, and all necessary corrections made by
the Contractor. Where any forms have been disturbed or any
subgrade becomes unstable, the forms shall be reset and
rechecked. In exceptional cases, the Engineer may require
stakes driven to the grade of the bottom of the forms.
Sufficient stability of the forms to support the equipment
operated thereon and to withstand its vibration without
springing or settlement shall be required. If forms settle
and/or deflect over 1/8 inch under finishing operations,
paving operations shall be stopped and the forms shall be
reset to line and grade.
r
Forms shall remain in place for not less than 12 hours
after the concrete has been placed. They shall be
carefully removed in such a manner that little or no
�.
damage will be done to the edge of the -pavement. Any
damage resulting from this operation shall be immediately
repaired. After the forms have been removed, the ends of
all joints shall be cleaned, and any honeycombed areas
r
pointed up with approved mortar. Immediately after
z
pointing is completed, the form trench, if used, shall be
filled with earth from the shoulders in such a manner as
r
to shed water from rainfall or curing away from the edge
of the pavement. On completion of the required curing, the
V-19
subgrade-or shoulders adjacent to the pavement shall be
graded in`a'condition to maintain drainage.
Allowable grade revisions shall in no way -affect the
governing finishing and surface requirements of the
completed pavement.
All grade revisions shall be established by the Engineer.
No additional payment over the contract unit price will be
made for any pavement of a thickness exceeding that
required on the plans as a result of adjustment of the
forms.
I. Concrete Mixing and Placing
1.Mixincr
The aggregates, mineral filler if required, cement and
.water shall -be measured separately, introduced into the
mixer, and mixed for a period of not less than 50 seconds
nor more than 90 seconds, measured from the time the.last "-
aggregate enters the drum to the time discharge of the
concrete begins. The required water shall be introduced
into the mixing drum during the first 15 seconds of mixing.... The entire contents of the drum shall be
discharged before any materials of the succeeding batch
are introduced.
The Engineer may increase the minimum mixing time to that
necessary to produce thoroughly mixed concrete based on
inspection or appropriate uniformity tests. The mixing
time may be varied at any time necessary to produce
acceptable concrete.
If Ready -Mix concrete is used, the concrete shall be
discharged into the specified hauling.equipment and
delivered to the road site: If truck agitators are used,
the concrete shall be continuously agitated at not less
than one nor more than six rpm as directed by the
Engineer.
The initial batch of concrete mixed after each time the
mixer is washed out shall be enriched by additional
mortar. The additional mortar shall be one sack of cement
and three parts of sand.
2. Placing
Any concrete not placed as herein prescribed within 30
minutes after mixing shall be rejected and disposed of as
directed except as provided otherwise herein. Except by
V-20
i
specific written authorization of the Engineer, concrete
shall not be placed when the temperature is below 400F,
the temperature being taken in the shade and away from
artificial heat.
1
When such permission is granted, the Contractor shall
furnish an approved enclosure, such as canvas -covered
framework, to enclose and protect all pavement so placed,
and shall maintain the temperature of the air surrounding
the concrete at not less' than 50OF for not less than 5
days. When concrete is being placed in cold weather, other
than under the conditions stated above, the Contractor
shall have available a sufficient supply of an approved
covering material to immediately protect concrete if the
air temperature falls to 320F, or below, before concrete
P"
has been placed 4 hours. Such protection shall remain in
place during the period the temperature continues below
320F or for a period of not more than 5 days. Neither salt
7
nor other chemical admixtures shall be added to the
concrete to prevent freezing. The Contractor shall be
responsible for the quality and strength of concrete under
r..
cold weather conditions and any concrete damage by
freezing shall be removed and replaced at his expense.
Concrete shall not be placed before sunrise and shall not
be placed later than will permit the finishing of the
pavement during sufficient natural light.
Concrete shall be placed only on approved subgrade or sub-
base, and unless otherwise indicated on plans, the full
width of the pavement shall be constructed monolithically.
The concrete shall be deposited on the subgrade or sub-
base in such manner as to require as little rehandling as
possible. Where hand spreading is necessary, concrete
shall be distributed to the required depth by use of
shovels. The use of rakes will not be permitted. Workmen
will not be permitted to walk in the concrete with any
s earth or foreign material an their boots or shoes. The
placing of concrete shall be rapid and continuous.
Concrete shall be distributed to such depth that when
consolidated and finished, the slab thickness required by
plans will be obtained at all points and the surface shall
not, at any point, be below the established grade. Special
care shall be exercised in placing and spreading concrete
against forms and at all joints to prevent the forming of
honeycombs and voids.
If in the opinion of the Engineer, the temperature, wind
�- and/or humidity conditions are such that the quality of
the concrete will not be adversely affected, the specified
placing time may be extended to a maximum of 45 minutes*.
V-21
3. Reinforcincx Stee
All reinforcing steel, including steel wire fabric
reinforcement, tie bars, and dowel bars shall be
accurately placed and secured in position in accordance
with details shown on plans. Reinforcing bars shall be
securely wired together at alternate intersections,.
following a pattern approved by the Engineer, and at all
splices, and shall be securely wired to each dowel
intersected. When wire fabric is used, it shall be
securely wired together at all splices and to each dowel "^
intersected. Tie bars shall be installed in the required
position by the method and device shown on plans or by
approved method and device equivalent thereto. ---
Tightly adhered scale or rust which resists removal by
vigorous wire brushing need not be removed except that _
excessive loss of section to the reinforcement due to rust
shall be cause for rejection. Excessive loss of section
shall be defined as loss of section to the extent that the
reinforcement will no longer meet the physical
requirements for the size and grade of steel specified.
Where plans require an assembly of parts at pavement
joints,, the assembly shall be completed, placed at
requiredl location and elevation, and all parts rigidly
secured in required position by the method and devices -
shown on plans. Dowel bars shall be accurately installed
in joint assemblies in accordance with plans, each
parallel to the pavement surface and to the center line of
the pavement, and shall.be rigidly secured in required -
position by such means (as shown on plans) that will
prevent their displacement during placing and finishing of
the concrete.
4. Joints
When the placing of concrete is stopped, a bulkhead of
sufficient cross sectional area to prevent deflection,
accurately notched to receive the load transmission
devices or dowels if required, and shaped accurately to
the cross section of the pavement shall be provided and
installed as a back-up for -the joint filler and rigidly
secured in required position to permit accurate finishing
of the concrete up to the joint. After concrete has been
finished to the joint, formation of the joint seal space
and finishing of the joint shall be executed. The back-up
bulkhead shall remain in place until immediately prior to
the time when concrete placing is resumed,.when it shall
be carefully removed in such manner that no element of the
V-22
r
joint assembly will be disturbed.- The exposed portion of
the joint assembly shall be free of adherent concrete,
` dirt or other material at the time placing of concrete is
resumed.
If necessary for proper installation of joint sealer,
excessive spalling of the joint groove shall be repaired
to the satisfaction of the Engineer in the manner which he
prescribes.
Careful workmanship shall be exercised in the construction
of all joints to insure that the concrete sections are
completely separated by an open joint or by the joint
materials and to insure that the joints will be true to
the outline indicated.
5. Weakened plane Joints
Weakened plane joints shall consist of transverse
contraction joints and longitudinal joints and.shall be
sawed as specified on the plans or as directed by the
Engineer. When the joints are sawed, the saw shall be
power driven, shall be manufactured especially for the
purpose of sawing concrete, and shall be capable of
performing the work. Saw blades shall be designed to make
a clean smooth cut having a width and depth of cut as
detailed on the plans. Tracks adequately anchored, chalk,
string line or other approved methods shall be used to
provide true alignment of the joints. The concrete saw
shall be maintained in good operating condition and the
Contractor shall keep a stand-by power saw on the project
at all times when concrete operations are under way.
If membrane curing is used, the portion of the seal which
has been disturbed by sawing operations shall be restored
by the Contractor by spraying the area with additional
curing seal.
6. Contraction Joints
Transverse contraction joints shall be formed or sawed
joints perpendicular to the centerline and surface of the
pavement. Where sawed joints are used, contraction joints
at approximately 10 to 15-foot intervals shall be sawed as
soon as sawing can be accomplished without damage to the
pavement and before 12 hours after the concrete has been
placed, the exact time to be approved by the Engineer. The
remaining contraction joints shall be sawed in a uniform
V-2 3
r
pattern as directed by the Engineer', and they shall be
- completed before uncontrolled cracking of the pavement
takes place. All joints shall be completed before
permitting traffic to use the pavement.
• 7. Longitudinal Joints
Longitudinal joints shall be sawed within two days after
construction of the pavement. Sawing shall not cause
damage to the pavement and the grooves shall be cut with a
minimum of spalling. No traffic (including construction -
traffic) shall be permitted on the pavement until the
longitudinal. joint, is- cut. '
8. Joint Sealers
After the joints in the hardened concrete have been
repaired (if necessary) and cleaned to the satisfaction of
the Engineer, the joints will be filled with the W.R.
Meadows SOF-SEAL. After the sealant is installed it will
effectively seal the joints against water, dirt and stones
throughout repeated cycles of expansion and contraction.
9. Asphalt Board
Premo-Ided materials,. wherever used, shall be anchored to
the,concrete on one side of the joint by means of copper
wire or nails not lighter than No. 12 B&S gage. Such -
anchorage shall be sufficient to overcome the tendency of
the material to fall out of the joint.
10. Spreading and Finishing
All concrete pavement shall -be consolidated by a
mechanical vibrator. As soon as the concrete has been
spread between the forms, the approved mechanical vibrator
shall be operated to consolidate the concrete and remove
all voids. Hand manipulated vibrators shall be used for -
areas not covered by the mechanical vibratory unit.
After finishing is completed and the concrete still
workable, the surface shall be tested for trueness with an
approved to -foot steel straightedge. 'The straightedge
shall. be operated from the side of the pavement, placed
parallel to the pavement centering and passed across the
slab to reveal any high spots or depressions. The
straightedge shall be advanced along the pavement in
successive stages of not more than one-half its length.
Practically perfect contact of the straightedge with the
surface will be required, and the pavement shall be
leveled to this condition, in order to insure conformity
V-24
r.. _ with the surface test required after the pavement has
fully hardened. Any correction of the surface required
shall be accomplished by adding concrete if required and
by operating the longitudinal float over the area. The
surface test with the straightedge shall then be repeated.
t Extra water will not be added for finishing.
After completion of the straightedge operation, the first
pass of the burlap drag shall be made as soon as
construction operations permit and before the water sheen
has disappeared from the surface. This shall be followed
by as many passes as required to produce the desired
texture depth. There shall be no unnecessary delays
between passes. The drag shall be wet during use and
maintained clean and free from encrusted mortar. It is the
intent that the average texture depth resulting from the
number of tests directed by the Engineer be not less than
0.025 inches with a minimum texture depth of 0.020 inches
for any one test. Should the texture depth fall below that
intended, the finishing procedures shall be revised to
produce the desired texture.
The Contractor shall have available at all times hand
brooms with stiff bristles for the purpose of providing
texturSs when the pavement surface is in such a condition
that the burlap drag or other methods being employed will
not provide the desired texture.
After completion of dragging and about the time the
concrete becomes hard; the edge of the slab and joints
shall be carefully finished as directed by the Engineer,
and the pavement shall be left smooth and true to line.
11. Protection of Pavement and Opening to Traffic
The Contractor shall erect and maintain the barricades
required by plans and such other standard and approved
devices as will exclude public traffic and traffic of his
employees and agents from the newly placed pavement for
the periods of time and at locations hereinafter
prescribed by the Engineer. Portions of the roadway, or
crossings of the roadbed required to be maintained open
for use by traffic, shall not be obstructed by the above
required barricades.
The pavement shall be closed to all traffic, including
vehicles of the Contractor, until the concrete is at least
7 days old. This period of closure to all traffic may be
extended if, in the opinion of the Engineer, weather or
other conditions make it advisable to provide an extension
of the time of protection.
V-25
At the end of the-7 day period and as long thereafter as
ordered by the Engineer; and if so desired by the
Contractor, the pavement may be opened for use by vehicles
of the Contractor provided,the gross weight (vehicle plus
load) of such vehicles does not exceed 14,000 pounds. Such
opening, however shall in no manner relieve the Contractor
from his responsibilities for the work. On those sections
of the pavement thus opened to traffic, all joints shall
first be sealed, the pavement cleaned and earth placed
against the pavement edges before permitting,vehicles
thereon.
After the concrete in any section is 14 days old, or as
long thereafter as ordered by the Engineer, such section
of pavement may be opened to all traffic as required by
plans or when so directed by the Engineer. On those
sections of the pavement thus opened to traffic, all
joints shall first be sealed, the pavement cleaned, earth
placed against the pavement edges and all other work
performed as required for the safety of traffic.
When High Early Strength Concrete, resulting from the use
of Type III cement as required by plans or special
provisions, is used, the pavement may be opened to all
traffiq after the concrete is 7 days old, or as long
thereafter as ordered by the Engineer, subject to the same
provisions governing the opening after 14 days as above
prescribed.
Where the Contractor desires to move any equipment not
licensed for operating on public streets, on or across any.
pavement opened to traffic, he shall protect the pavement
from all damage by means of two-ply timber mats of 2 inch
stock or runways of heavier material laid on a layer of
earth, all as approved by the Engineer.
The Engineer may require the opening.of pavement to
traffic prior to the minimum time specified above under
conditions of emergency which in his opinion require such
action in the interest of the public. In no case shall the
Engineer order opening of the pavement to traffic within
less than 72 hours after the last concrete in the section
is placed. The Contractor shall remove al`l obstructing'
materials, place earth against the pavement edges and
perform other work involved in providing for the safety of
traffic as required by the Engineer in ordering emergency
opening.. Orders for emergency opening of the pavement to
traffic will be issued by the Engineer.in writing.

Sub -grade preparation shall include the removal, haul and
disposal of all obstructions, including existing curbs,
gutters, paving materials;'base materials, concrete slabs
and other obstructions shown on the plans or as designated
by the Engineer and all scarifying, pulverizing, wetting,
disking, blading and rolling with compactors to a depth of
,.
at least 6" on residential streets and to a depth of 12"
on major thoroughfares and collector streets. Compactors
will be used from the bottom to the finished sub -grade
elevation to compact the subgrade to 95% Standard Proctor
r
Density (A.S.T.M. D-698) in conformity to the line, grade
and sections as shown on the plans or as established by
the Engineer.

After the obstructions have been removed, or in
conjunction with such removal, the street bed and/or alley
returnJoundation and/or sidewalk foundation shall be
excavated and shaped in conformity with the typical
section and to the line and grades as shown on the plans
or as established by the Engineer.
All unstable or otherwise objectionable material shall be
removed from the subgrade and replaced with approved
material. The excavation shall be done in such a manner as
to require a minimum of fill to bring .the subgrade to the
correct elevation. When the subgrade is too low as
initially excavated, the Contractor shall place additional
soil or caliche in layers not exceeding four (411) inches
and compact each layer by moistening and rolling.
1. Scraper Work
The utilization of a scraper for excavation and shaping of
subgrade and base is permitted with exceptions which are
determined by depths of utility lines. Unless otherwise
specified by the Engineer, the scraper shall not exceed 23
cubic yards capacity as rated loaded flush by the
manufacturer.
2. Compaction
Subgrade shall be compacted to 95% Standard Proctor
Density (A.S.T.M. D-698) for all improvements except

Abe compacted to.1001 Standard Proctor Density for
thoroughfare and collector street paving.
Density tests (A.S.T.M. D-2922) will be performed and test
rolling will be observed by City inspectors.
Swelling subgrade (soils with plasticity index of 20 or
more),shall be sprinkled as required to provide not less
than optimum moisture during compaction. Other subgrade
soils will be compacted at moisture content of plus or
minus 2% of 2% below optimum moisture or other moisture
content directed by the Engineer'.
Test rolling will be accomplished with a,25 ton pneumatic
tire roller or other pneumatic tire roller approved by the
Engineer. The Engineer may require up to six passes of
the roller in determing the condition of the subgrade.
Any soft or unstable areas found by test rolling will be
corrected by removing the soft or unstable material and "
replacing it with suitable compacted to specified density.
The areas so corrected shall be test rolled as specified
above.
3. Inters;ction
Special care shall be exercised in grading street
intersections where dips are located so that the cross
profiles present a smooth riding surface and so that the
compacted base thickness will not be less than six (611) or
nine (911). Crown section shall begin to decrease 60 feet
back of.end of radius for residential streets. Wider
street dips will be blue topped as shown on the detail
sheet.
4. Prosecution of the Work
The Contractor may proceed with subgrade preparation on
any schedule he may select except that, unless hindered by.
factors beyond his control, not more than seven (7)
calendar days shall elapse between the time subgrade
preparation ,is begun and the spreading and compacting of
the base has started. Measures shall betaken bythe
contractor not to leave driveways impassable during the
night hours.
5. Excess Materials
Materials excavated in excess of that needed in fill and
backfill behind curb shall be wasted by the Contractor.
V-28
t i
Care shall be taken by the Contractor to use only topsoil
in the backfill behind the curbs. The Contractor may
dispose of the surplus excavated material in any manner
not objectionable to the public, and it is his
responsibility to locate a suitable site for dumping the
waste excavation. In any event, the Contractor shall not
dispose of the surplus materials in any of the lake areas
either outside or within the city limits. Location of
disposal sites near any lake area must be approved by the
l Engineer.
6. Subarade for Alley Paving
The preparation of the subgrade for concrete alley paving
�.. shall be done in the same manner as other subgrade
excavation which requires scarifying, wetting, disking,
blading, rolling, and compacting. The Contractor will be
required to excavate around existing improvements such as
gas meter, water meters, poles, etc._.Each of these
obstructions shall be the responsibility of the
Contractor. Trees that conflict with the improvements
r- shall be removed by the Contractor upon approval of the
+ Engineer.
k
The Contractor shall shape to subgrade to the cross-
secti6r0 shown on the plans and to the lines and grades
established by the Engineer. After the forms are set and
before the reinforcing is placed, the.Contractor shall
finally shape the subgrade so that there will be a minimum
thickness of concrete of five (511) inches at the
centerline and seven and one-half inches (7-1/211) at the
outside edges. All areas where fill material is required
shall be compacted. The subgrade shall be wetted and
rolled to secure 90% Proctor Density in the upper six (611)
making a firm foundation for the alley paving.
The Contractor will be required to

hauled to any approved location.
B. Embankment
Description
Prior to placing any
Way" and/or "Clearing
been completed on the
which the embankment
small excavations in
shape the portion of
the concrete slab so
be to the invert of
materials shall be
embankment, all "Preparing Right -of -
and Grubbing" operations shall have
excavation sources and areas over,
is to be placed. Stump holes or other
the limits of the embankment shall be
V-29
backfilled with suitable material and thoroughly tamped by
approved methods before commencing embankment
construction. The surface of the ground, including plowed
loosened ground, or surface roughened by small washes or
otherwise, shall be restored to approximately its original
slope by blading or other methods and where indicated on
plans or required by the Engineer, the ground surface thus —
prepared shall be compacted by sprinkling and rolling.
Where embankments are to be placed adjacent to or over —
existing roadbeds, the roadbeds slopes shall be plowed or
scarified to a depth of not less than six (611) inches and
the embankment built up in successive layers, as
hereinafter specified, to the level of the old roadbed
before its height is increased. Then, if directed, the top
of the roadbed shall be scarified and recompacted with the
next layer of the new embankment. The total depth of the .-
scarified and added material shall not exceed the
permissible depth of layer.
Trees, stumps, roots, vegetation, or other unsuitable
materials shall not be placed in embankment.
Except as otherwise required by the plans, all embankment
shall._.be constructed in layers approximately parallel to
the finished grade of the roadbed and unless otherwise
specified each layer shall be so constructed as to provide
a uniform slope of 1/4" inch per foot from the center line
of the roadbed to the outside.
Embankments shall be constructed to the grade established•
by the Engineer and completed embankments shall correspond
to the general shape of the typical sections shown on the
plans and each section of the embankment shall correspond
to the detailed section or slopes established by the
Engineer. After completion of the roadway, it shall be
continuously maintained to its finished section and grade
until the project is accepted.
Except as otherwise specified, earth embankments shall be
constructed in successive layers for the full width of the
individual roadway cross section and in such lengths as
are best suited to the sprinkling and compaction methods
utilized.
Layers of embankment may be formed by utilizing equipment
which will spread the material as it is dumped, or they
may be formed by being spread by blading or other
acceptable methods from piles or windrows dumped from
excavating or hauling equipment in such amounts that
material is evenly distributed.
V-30
I ..
Minor quantities of rock encountered in constructing earth
embankment shall be incorporated in the specified
embankment layers, or may be placed in accordance with the
requirements for the construction of rock embankments in
r the deeper fills within the limits of haul shown on the
! plans, provided such placement of rock is not immediately
adjacent to structures. Also, rock may be placed in the
portions of embankments outside the limits of the
completed roadbed width where the size of the rock
prohibits their incorporation in the normal embankment
layers.
Each layer of embankment shall be uniform as to material,
density and moisture content before beginning compaction.
Where layers of unlike materials abut each other, each
layer shall be featheredged for at least 100 feet or the
material shall be so mixed as to prevent abrupt changes in
the soil. No material placed in the embankment by dumping
in a pile or windrow shall be incorporated in a layer in
that position, but all such piles or windrows shall be
moved by blading or similar methods. Clods or lumps of
material shall be broken and the embankment material mixed
by blading, disking, or similar methods to the end that a
uniform material or uniform density is secured in each
layer...Water required for sprinkling to bring the material
to the moisture content necessary for maximum compaction
shall be evenly applied and it shall be the responsibility
of the Contractor to secure a uniform moisture content
throughout the layer by such methods as may be necessary.
In order to facilitate uniform wetting of the embankment
material, the Contractor shall water at the material
source if the sequence and methods used are such as not to
cause an undue waste of water. Such procedure shall be
subject to the approval of the Engineer.
F1. Compaction
The compaction method shall require that each layer shall
be compacted to the required density by any method, type,
and size of equipment which will give the required
compaction. The depth of layers, prior to compaction,
�- shall depend upon the type of'sprinkling and compaction
equipment used. Prior to and in conjunction with the
rolling operation, each layer shall be brought to the
�. moisture content necessary to obtain the required density
and shall be kept leveled with suitable equipment to
insure uniform compaction over the entire layer.
T" For each layer of earth embankment and select material, it
is the intent of this specification to provide the density
as required herein, unless otherwise shown on the plans.
r
R
r•
V-31
r
The required compaction shall be'95% Standard Proctor
Density A.S.T.M. D-698.
After each section of earth embankment or select material
is complete, tests as necessary will be made by the
Engineer. If the material fails to meet the density
specified, the course shall be reworked as necessary to
obtain the specified compaction,' and the compaction method
may be altered on subsequent work,to obtain specified
- density. Such procedure shall be determined by, and
subject to, the approval of the Engineer.
At any time, the Engineer may order proof rolling to test
the uniformity of compaction of the embankment subgrade.
All irregularities, depressions, weak or soft -areas which
develop shall be corrected immediately by the Contractor.
Should the subgrade, due to any reason or cause, lose
required stability, density, or finish before the pavement
structure is placed, it shall be recompacted and
refinished at the sole expense of the Contractor.
Excessive loss of moisture in the subgrade shall be
prevented by sprinkling, sealing, or covering with a
subsequent layer of granular material. Excessive loss of
moisture shall be construed to exist when the subgrade
soil moisture content is more than 4 percent below the
optimum for compaction to Standard Proctor Density. (Also ,
see Section V, Item 2 [A] Compaction.)
At Culverts
Embankments adjacent to culverts which cannot be compacted
by use of the blading and rolling equipment -used in
compacting the adjoining sections of embankment shall be
compacted in the manner prescribed below.
The following requirements shall apply to the backfilling
of pipe culverts in addition to the pertinent portions of
the general requirements,given in the preceding section.
After the bedding has been prepared and the pipe installed
as required by the pertinent specifications, selected
materials from excavation or borrow shall be placed along
both sides of -the pipe equally, in uniform layers not to
exceed six (611) inches in depth (loose measurement),
wetted and thoroughly compacted so that on each side of
the pipethere shall be a berm of thoroughly compacted
materials at least as wide as the external diameter of the
pipe, except insofar as undisturbed material obtrudes into
this area. The method and degree of compaction shall be
same as specified above.
V-32
r•
r-
C
Filling and/or backfilling shall be continued in this
manner to the elevation of the.top of the pipe. Special
care shall be taken to secure thorough compaction of the
material placed under the haunches of the pipe. All fill
or backfill below the top of the pipe shall be compacted
mechanically in the same manner and to the density
prescribed above, regardless of whether or not such
material is placed within the limits of the embankment or
roadbed.In the case of embankments, the remainder of the
fill above the top of pipe shall be placed in accordance
with the provisions for placing roadway embankment as
prescribed in the pertinent specification included in the
contract. No construction traffic will'be permitted to
cross any pipe culvert until the minimum depth of fill
above the pipe as determined by the Engineer has been
placed and consolidated.
3. BASE COURSE
The base course shall consist of a minimum of six (611) or
nine (911) inches of compacted approved caliche, black base
or combination of caliche and black base material shaped
in accordance with the typical cross -sections provided in
the plans and to the grades established by the Engineer.
A. Haulina�and Placing
Approved base material shall be hauled in vehicles of
uniform capacity to the site and dumped evenly so that an
adequate quantity of material will be placed to provide a
minimum of six (611) inches of compacted base material on
all units except major thoroughfares streets. On these
streets the Contractor will construct nine (911) inches of
compacted base material.
B. Processing
Processing of caliche base shall be accomplished in
mulitiple lifts of three (311) inches in compacted depth.
Each lift or layer shall be thoroughly moistened and
rolled as it is cut from the windrow. After all of the
material is cut from the windrow to the sides, it shall be
cut back to the center in lifts of three (311) inches and
thoroughly moistened and rolled again. Succeeding layers
shall then be placed similarly until the caliche base
course is completed.
Caliche'base shall be compacted

rolling for base will be observed by City inspectors.
Caliche base shall be compacted at a moisture content of
plus or minus 2% of 2% below optimum moisture or other
moisture content directed by the Engineer.
The finished caliche base shall be test rolled with a 25
ton pneumatic tire or other approved roller. The Engineer
may require up to six passes of the roller in determining
the condition of the base. -
All nine-(9") inch compacted caliche base shall be
accomplished in three (311) inch lifts. The caliche course --
shall then be sprinkled as required and rolled with
compactors.as directed until a uniform compaction of
specified "Standard Proctor Density" is secured. _
Throughout this entire operation, the shape of the course
shall be maintained by blading; and the surface upon
completion shall be smooth and in conformity with the
typical sections shown on plans and to the established
lines and grade.
Traffic may be allowed to travel on the caliche base, as
directed by the Engineer, during construction. During
this period, the caliche base shall be satisfactorily
maintained by the use of water trucks, blades, drags and
such other equipment as may be required. The base course
shall be so maintained until the wearing surface is placed
thereon. The surface shall not be placed on base course
that exceeds optimum mixture by two percent (2$).
Processing of asphaltic base shall be as directed by the
Engineer and similar to that described under Not Mix
Asphaltic Concrete Surface. Lift thickness will be
indicated by the Engineer or as shown on the paving plans:
Electronic screed controls will be required for placing
black base on grade. The density required will be
determined by the Engineer after material to be used has
been approved. All areas and "nests" of segregated coarse
or fine material shall be corrected or removed and
replaced with well graded material as directed by the
Engineer.
Each layer of black base may be test rolled, as directed
by the Engineer, with a 25 ton pneumatic tire or other
approvedrollerrequiring up to six passes before
succeeding layers are placed. A delay in construction of
a black base mat or surface will require test rolling and
approval prior to construction of the next layer.

C. Finishincx
Description
The compacted base shall be finished and shaped
immediately preceding the application of the surface
treatment. All loose or unconsolidated material shall be
removed and the surface moistened and rolled with a steel
f" wheel roller.
1. Failed Density or Weak Spots in Base
The finished caliche base shall be checked for density
`
requirements and by test rolling. Materials that fails
the density requirement shall be reworked as necessary
r
until passing. The full depth of caliche base shall be
1
compacted to the extent necessary to remain firm and
stable under test rolling. All irregularities,
!�
depressions or weak spots which develop shall be corrected
immediately by scarifying the areas affectd, adding
suitable material as required, reshaping and recompacting
r.
by sprinkling and rolling. If the Contractor chooses, he
may repair the weak spot by removing the material involved
and replacing it with type "C" hot mix or asphalt
stabilized base. In this case, the surface may be applied
as soon1as the hot mix patch has been compacted and cooled
(
to ambient temperature.
2. Allowable Deviation in Finish
Immediatelv_rrior_to Dlacina of surfacing, the base shall
be -checked -and any deviation in excess of three -eights
_
(3/8) inch from the established grade or true cross
section shall be corrected as ►provided above for defects._
Longitudinally a straightedge 10 feet long shall be used
to detect any deviation which shall be corrected as
defects.
4. HOT MIX ASPHALTIC CONCRETE SURFACE
A. Description
This item shall consist of 1-1/2" compacted C.O.L. Type
"C" or Type "D" hot mix asphaltic concrete surface, using
approved crushed stone aggregate, constructed over a
compacted base. The base shall be primed and a tack coat
applied as required.
1. Sampling and Testing Hot Mix Asphaltic concrete for
Compaction
V-35
r-�
Hot mix asphaltic concrete will be accepted on'a lot
basis. A lot will consist of 1000 tons or each days
production and will be divided into three (3) equal
sublots. Pavement density will be determined by taking
the average density for each lot, from the three sublots,
the average Maximum Theoretical Density, taken from trucks
delivering hot mix asphaltic concrete to the site. The
samples will be tested in accordance with ASTM D-2041.
Each lot of compacted pavement will be accepted, with
respect to density, when the average field density is
within the below, listed specifications. Four field
density determinations will be made for each lot. Cores
taken from the pavement will be used to test the field
density. The density of the cored samples will be
determined in accordance with ASTM D-2726.
Density Specifications
Based on Maximum Theoretical Density
Minimum = 92.5%
Optimum 96.0%
Maximum 97.5%
If the mixture produced does not have the specified
qualities; it shall be adjusted until it does. The
pavement shall be constructed on the previously completed
and approved subgrade, base, existing pavement, bituminous
surface or in the case of a bridge, on the prepared floor
slab, as herein specified and in accordance with the
details shown on the plans.
2. Temperature Requirements
A. November 1 until April 1
1. The asphaltic mixture shall not be placed when the air
temperature is below 55 degrees F and falling.
2. The asphaltic mixture may be placed when the air
temperature is above 50 degrees F and rising.
B. April 1 till November 1
1. The asphaltic mixture shall not be placed when the air
temperature.is-below 50 degrees F and falling.
2. The asphaltic mixture may be placed when the air
temperature is -above 45 degrees F and rising.
V-36
The air temperature shall be taken in the shade away from
artificial heat or as reported by the National Weather
Service on their hourly report.(Telephone No. 762-0141).
�- The Engineer may use his discretion to require a cover
over the asphaltic mixture when being hauled from the
plant to the job site.
If the temperature of a load of asphaltic concrete
measured while passing through the lay -down machine is 25
degrees F less than the mixing temperature, the load may
be rejected by the Engineer and payment will not be made
for the rejected material.
3. Preparation of Base and Areas Bordering
The compacted base upon which the hot mix asphaltic
concrete surface is to be placed shall be prepared and
cleaned, as required by the Engineer, before the prime
coat is applied.
4. Prime Coat
The prime coat shall consist of an application of .25
gallons. per square yard _of MC asphalt.
5. Tack Coat
Before the asphaltic mixture is laid, the surface upon
which the tack coat is to be placed shall be cleaned
thoroughly to the satisfaction of the engineer. The
surface shall be given'a uniform application of tack coat
using asphaltic materials of this specification. This tack
coat shall be applied, as directed by the. engineer, with
approved sprayer. Where the mixture will adhere to the
surface on which it is to be placed without the use of a
tack coat, the tack coat may be eliminated by the
Engineer. All contact surfaces of curbs and structures and
all joints shall be painted with a thin uniform coat -of
the asphaltic material meeting the requirements for tack
coat. The tack coat shall be rolled with a pneumatic tire
roller as directed by the Engineer.
6. Transporting Asphaltic Concrete
The asphaltic mixture, prepared as specified above shall
be hauled to the work site in tight vehicles previously
cleaned of all foreign material. The dispatching of the
vehicles shall be arranged so that all material delivered .
may be placed, and all rolling shall be completed during
day -light hours. The inside of the truck body may be
V-37
given a light -coat of oil,'lime slurry or other material
- -satisfactory to the Engineer, if necessary, to prevent
-mixture from adhering to the body. In cool weather or for _
long hauls, canvas covers and insulating of truck bodies
may be required. Vehicles of the semi -trailer type are
prohibited.
7. Placing
Generally the asphaltic mixture shall be dumped and spread on the approved prepared surface with the specified
spreading and finishing machine in such manner that when
properly compacted the finished pavement will be smooth, _
of uniform density and will meet,the requirements of the
typical cross sections and the surface tests. During the
application of asphaltic material, care shall be taken to
prevent splattering of adjacent pavement, curb and gutter, and structures.
The surface course shall be laid in a compacted layer with
a minimum compacted thickness of one and one-half inches
A level up course, 1/2" or more in thickness, shall -
require the use of black base or a coarse grade of hot mix
approved by the Engineer. It shall be spread and
compacted to lines and grades as established by the
Engineer.
When the asphaltic mixture is placed in a narrow.strip
along the edge of an existing pavement, or used to level .
up small areas of an existing pavement or placed in small
irregular areas where the use of a finishing machine is
not practical, the finishing machine may be eliminated
when authorized by the Engineer, provided a satisfactory
surface can be obtained by other approved.methods.
Adjacent to flush curbs, gutters, liners and structures,
the surface shall be finished uniformly high so that when
compacted it will be slightly above the edge of the curb
and flush structure.
All joints shall present the same texture density, and
smoothness as other sections of the course. The joints
between old and new pavements or between successive days
work shall be carefully made to insure a continuous bond
between-`old°and new sections of the course.
The transverse edges of old pavement and, if required by -
the Engineer, the successive days pavement shall be sawed
with an approved concrete saw to expose an even vertical
V-38
f r
surface for the full thickness of the course. All contact
r` surfaces of previously constructed pavement shall be
painted with a thin uniform coat of hot bituminous
material before the fresh mixture is placed.
8. Comnactincr
As directed by the Engineer, the pavement shall be
compacted thoroughly and uniformly to the required
density. The specified rollers shall be used, except as
provided in paragraph (3) below.
Rolling with the three wheel and tandem rollers.shall
start longitudinally at the sides and proceed toward the
center of the pavement, overlapping on successive trips by
at least half the width of the rear wheels unless
otherwise directed by the Engineer. Alternate trips of
the roller shall be slightly different in length. On
super -elevated curves, rolling shall begin at the low side
and progress toward the high side unless otherwise
directed by the Engineer. Rolling with pneumatic roller
shall be done as directed by the Engineer. Rolling shall
be continued until required compaction is obtained and all
roller marks are eliminated. one tandem roller, two
pneumatic rollers and at least one three wheel roller, as
speci,fled above,.shall be provided for each job.
Additional rollers shall be provided if needed.The motion
of the roller shall be slow enough at all times to avoid
displacement of the mixture. If any displacement occurs,it
shall be corrected at once by the use of rakes and of
fresh mixture where required. The roller shall not be
allowed to stand on pavement which has not been fully
compacted. To prevent adhesion of the surface to the
roller, the wheels shall be kept thoroughly moistened with
water, but an excess of water will not be permitted. All
rollers must be in good mechanical condition. Necessary
precautions shall be taken to prevent the droppings of
gasoline, oil, grease or other foreign matter on the
pavement, either when the rollers are in operation or when
standing.
When indicated on the plans or permitted by the Engineer
in writing, the pavement may be compacted to the required
density by the use of compacting equipment other than that
specified herein.
Hand tamping. The edges of the pavement along curbs,
headers and similar structures, and all places not
accessible to the roller, or in such positions as will --not
allow thorough compaction with the roller, shall be
thoroughly compacted with lightly oiled tamps.
V-39
Rolling.with the trench type roller will be required on
widening areas in trenches and other limited areas where
satisfactory compaction cannot be obtained with the three
wheel and tandem rollers.
9. Surface Tests
The surface of the pavement, after compaction , shall be
smooth and true to the established line, grade and cross
section, and when tested with a 10 foot straight edge
placed parallel to the centerline of the roadway or tested
by other equivalent and acceptable means, except as
provided herein, the maximum deviation shall not exceed
1/8 inch in 10 feet, and any point in the surface not —
meeting this requirement shall be corrected as directed by
the Engineer. When placed on existing surfaces, the 1/8
inch deviation in 10 feet requirement may be waived by the
Engineer.

Dumping of the asphaltic mixture in a windrow and then
placing the mixture in the finishing machine with loading
equipment will be approved by the Engineer,provided that
the loading equipment is constructed and operated in such
a manner that substantially all of the mixture deposited
on the roadbed is picked up and placed in the finishing
machine without contamination by foreign material of the
mixture. The loading equipment will be.so designed and
operated that the finishing machine being loaded will
obtain the required line, grade and surface without
resorting to hand finishing. Any operation of the loading
equipment resulting in the accumulation and subsequent
shedding of this accumulated material into the asphaltic
mixture will not be permitted.
Forms. The use of forms will not be required except where
necessary to support the edges of the pavement during
rolling. If the pavement will stand rolling without undue
movement, binder twine or small rope may be used to align
the edges.

finished grade after the base has been finished to grade.
The Contractor shall allow the City Forces at least 3 days
to do this work after finishing the base and before
application of asphalt. It shall be the responsibility of
the Contractor to notify the Water and Sewer Department 48
hours after curb and gutter has been completed so that the
City Forces can properly schedule their work. In all
alleys the City Forces will set the valve boxes and
manholes to grade after the forms are in place. Any
variation in this procedure that causes expense to the
City shall have the approval of the Engineer, and such
expense shall be borne by the Contractor.
The plans show only approximate locations of utilities as
obtained from the various utility companies and shall not
relieve the. Contractor from. familiarizing himself -with all
underground utilities. It is not implied that all existing
utilities are shown on the plans. The City of Lubbock does
not assume any responsibility for any utility lines which
are not shown on the plans.
The utility companies will attempt to move all utilities
that can be reasonably removed prior to beginning of
construction; however, this does not relieve the
Contractor from any damage that he might do to any utility
property. In case of any damage, the Contractor shall
r immediately notify the utility company.

Sequence: The sequence of utility adjustments has been
mutually agreed upon by the utility companies in the City
-of Lubbock and will attempt to follow the following
schedule:
Plans for contract project will be delivered to all,
utility companies two weeks prior to opening bids. As a
general rule, these projects will have been staked.
The utility companies will relocate all items necessary,
locate and flag all meters, valves, manholes, underground
cables, etc., prior to the date the Contractor is to begin
construction.
After the subgrade is completed on alley paving projects,
and after the base is completed on all street paving
projects, all manholes, -valve boxes , etc., will be set to
finished grade by the utility companies.'The site shall be
left in a clean condition.
On all projects, including private contracts, the
Contractor shall exercise care not to damage any sanitary
sewer pipe -or manholes, storm sewer pipe or manholes, or
telephone cable or manholes, water or gas lines, valve
boxes , meter boxes, nor any other pipe or utility. If -
necessary, the Contractorshall call the department or. -
company concerned and make arrangements for adjusting the
manhole, valve box, meter box,or other utility to grade.
On all projects for which he is awarded a contract, the
Contractor will be responsible during the construction
period for any damages to manholes, valve boxes, meter
boxes, and other utilities.
Should any item be damaged during the process of
construction, the Contractor is to notify the affected
utility company and the City inspector. The utility
company will immediately repair the damaged item. Any
bills for damage will be sent through the Department of
Engineering: The Department of Engineering will process
all bills and fix responsibility for damage and govern the
extent of repair.
V-44
�- -
Private contracts do not have plans, but utility companies
r -
will be furnished cut sheets and notified of impending
'
construction by letter. Other items such as adjustments,
damages, etc. will be handled the same as for bid let
r
projects.
The utility companies will schedule their work with the
Contractor. When utility adjustments commence before the
contract is awarded, it will be the responsibility of the
utility company to barricade the project.
Unless otherwise agreed upon by the City and the utility
companies involved, the sequence of installation of
underground utilities shall be as follows:

material at points where underground utilities cross or
propose to cross until such utilities have been adjusted
or installed.
7. SALVAGING AND REPLACING BASE
A. Description
"Salvaging and Replacing Base" shall consist of removing
the existing base material where shown on plans, such
temporary storage as is necessary, and the replacement of
this material on the prepared roadbed as herein specified
V-45
r
i
C
and in conformity with the typical sections shown on plans ^
and to the lines and grades as established by the engineer.
B. Construction Methods
1. Salvaainct Existing_ Base
The existing base, including any bituminous mat not shown
on plans to be salvaged, shall first be cleaned of all dirt
or other objectionable material by blading, brooming or
other approved methods, then scarified to the width and
depth as may be required to provide'the estimated amount of
salvaged material per station as shown on the plans.
Subgrade shall be reworked, if necessary, as directed by
the Engineer. Any bituminous mat encountered shall be
broken into particles not more than two inches in size, and
incorporated uniformly with the existing base. The material
thus salvaged shall be placed in stockpiles or windrows
until sufficient subgrade has been prepared to receive the
salvaged material; then, if the Contractor so elects, the
remaining old base material as salvaged may be placed
directly upon the prepared subgrade as directed by the
Engineer, thus eliminating the necessity of stockpiling. It
shall be the responsibility of the Contractor that all the
available material shall be salvaged and replaced and shall
be kept reasonably free of soil from the subgrade or
roadbed during the salvaging and replacing operations. When
material is windrowed or stockpiled, it shall be so placed
not to interfere with traffic, proper drainage or the
general progress of the work.
2. Preparation of Subgrade
Preparation of subgrade shall be in accordance with Section
V, Item 2 Earth Work of these specifications.
3. Replacement of -Salvage Material
The salvage material shall be in accordance with Section V,
Item 2 Earth Work of these specifications.
8. SALVAGING AND STOCKPILING BASE MATERIAL

or directed by the Engineer.
B. Construction Methods
V-46
Trash, wood, brush, stumps and other objectionable material
at the storage site shall be removed and disposed of as
directed by the Engineer prior to the beginning of work
required by this item. The base material, including any
asphalt mat, which may not be shown on the plans, shall be
cleaned of all dirt or other objectionable material.
Asphaltic materials shall be broken into pieces not more
than two inches in size and incorporated uniformly with the
salvaged base material. Material to be salvaged shall be
worked into stockpiles or windows and loaded by approved
equipment into approved equipment for hauling to the
stockpile site. It shall be the responsibility of the
Contractor that all the available material shall be
salvaged and kept reasonably free of soil from subgrade or
r
road bed during the salvaging operations. The operation
shall be conducted in such manner as not to interfere with
traffic, drainage or the general requirements of the work.
r
After the material is deposited in the stockpile area, it'
shall be worked into a neat compact stockpile.
9. TOLERANCE IN PAVEMENT THICKNESS
The thickness of the pavement shall be determined by average
caliper measurement of cores tested in accordance with ASTM
C-174.
Pavement thickness shall be not less than the specified
minimum thickness.
When the measurement of any core is less than the specified
minimum thickness,. the actual thickness of the pavement in
this area shall be detemined by taking additional cores at
not -less than 10-foot intervals parallel to the centerline in
each direction from the affected location until each
direction from the affected location until in each direction
a core is found which is not deficient. Areas found
deficient in thickness shall be removed and replaced with
