Contractor of good material, and of his performing good work as herein described, and in full accordance
with the plans and specifications. No failure or omission of the Engineer to discover, object to or
condemn any defective work or material shall release the Contractor from the obligations to fully and
properly perform the contract, including without limitations, the obligation to at once tear out, remove
and properly replace the same at any time prior to final acceptance upon the discovery of said defective
work or material; provided, however, that the Engineer shall, upon request of the Contractor, inspect
and accept or reject any material furnished, and in event the material has been once accepted by the
Engineer, such acceptance shall be binding on the Owner, unless it can be clearly shown that such
material furnished does not meet the specifications for this work.
Any questioned work may be ordered taken up or removed for re- examination, by the Engineer, prior to
final acceptance, and if found not in accordance with the plans and /or specifications for said work, ali
expense of removing, re -examination and replacement shall be borne by the Contractor, otherwise the
expense thus incurred shall be allowed as Extra Work, and shall be paid for by the Owner: provided
that. where inspection or approval is specifically required by the specifications prior to performance of
certain work, should the Contractor proceed with such work without requesting prior inspection or
approval he shall bear all expense of taking up, removing, and replacing this work if so directed by the
Engineer.
2.14 Defects and Their Remedies
It is further agreed that if the work or any part thereof, or any material brought on the site of the work
for use in the work or selected for the same, shall be deemed by the Engineer as unsuitable or not in
conformity with the plans, specifications, or the intent thereof, the Contractor shall, after receipt of
written notice thereof from the Engineer, forthwith remove such material and rebuild or otherwise
remedy such work so that it shall be in hill accordance with this contract.

any part thereof, either before or after the beginning of the construction, without affecting the validity
of this contract and the accompanying Performance and Payment Bonds.
If such changes or alterations diminish the quantity of the work to be done, they shall not constitute the
basis for a claim for damages, or anticipated profits on the work that may be dispensed with, except as
provided for unit price items under Section 5 "Measurement and Payment." If the amount of work is
increased, and the work can fairly be classified under the specifications, such increase shall be paid for
according to the quantity actually done and at the unit price, if any, established for such work under
this contract, except as provided for unit price items under Section 5 "Measurement and Payment ";
otherwise, such additional work shall be paid for as provided under Extra Work. In case the Owner shall
make such changes or alterations as shall make useless any work already done or material already
furnished or used in said work, then the Owner shall recompense the Contractor for any material or labor
so used. and for any actual loss occasioned by such change, due to actual expenses incurred i[. prepara-
tion for the work as originally planned.

inspectors may also communicate between Engineer and Contrator their respective reports, opinions,
questions, answers and clarifications concerning the plans, specifications and work but shall be deemed
the agent of the Contractor for all purposes in communicating such matters.
Such inspector may confer with the Contractor or Contractor's superintendent concerning the prosecu-
tion of the work and its conformity with the plans and specifications but shall never be, in whole or part,
responsible for, charged with, nor shall he assume, any authority or responsibility for the means,
methods or manner of completing the work or of the superintendence of the work or of the Contractor's
employees. It is expressly understood and agreed that any such inspector is not authorized by the Engi-
neer or Owner to independently act for either or answer on behalf of either, any inquiries of the Con-
tractor concerning the plans, specifications or work. No inspector's opinion; advice; interpretation of the
plans or specifications of this contract; apparent or express approval of the means, methods or manner
of Contractor's performance of work in progress or completed; or discovery or failure to discover or
object to defective work of materials shall release Contractor from his duty to complete all work in strict

fi Prosecution and Progress -
4.01 Time and Order of Completion
It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Con-
tractor shall be allowed to prosecute his work at such times and seasons, in such order of precedence.
and in such manner as shall be most conducive to economy of construction; provided, however, that the
order and the time of prosecution shall be such that the work shall be substantially completed as a whole
and in part, in accordance with this contract, the plans and specifications, and within the time of -com-
pletion designated in the Proposal; provided, also, that when the Owner is having other work done,
either by contract or by his own force, the Engineer may direct the time and manner of constructing the
work done under this contract, so that conflict will be avoided and the construction of the various works
being done for the Owner shall be harmonized.
The Contractor shall submit, at such times as may reasonably be requested by the Engineer, schedules
which shall show the order in which the Contractor proposes to carry on the work, with dates at which
the Contractor will start the several parts of the work, and estimated dates of completion of the several
parts.
4.02 Extension of Time
Should the Contractor be delayed in the completion of the work by any act or neglect of the Owner or
Engineer, or of any employee of either, or by other contractors employed by the Owner, or by changes
ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoid•
able cause or causes beyond the Contractor's control, or by any cause which the Engineer shall decide
justifies the delay, then an extension of time shall be allowed for completing the work, sufficient to com-
pensate for the delay, the amount of the extension to be determined by the Engineer, provided, however,
that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay.
4.03 Hindrances and Delays
No claims shall be made by the Contractor for damages resulting from hindrances or delays from any
cause (except where the work is stopped by order of and for the convenience of the Owner) during the
progress of any portion of the work embraced in this contract. In case said work shall be stopped by the
act of the Owner, then such expense as in the judgment of the Engineer is caused by such stoppage of
said work shall be paid by the Owner to the Contractor.
5. Measurement: and Payment
5.01 Quantities and Measurements
No extra or customary measurements of any kind will be allowed, but the actual measured and /or com-
puted length, area, solid contents, number and weight only shall be considered, unless otherwise spe-
cifically providea.
5.02 Estimated Quantities
This agreement, including the specifications, plans and estimate, is intended to show clearly all work to
be done and material to be furnished hereunder. Where the estimated quantities are shown for the
various classes of work to be done and material to be furnished under this contract, they are approxi.
mate and are to be used only as a basis for estimating the probable cost of the work and for comparing
the proposals offered for the work. It is understood and agreed that the actual amount of wort: to be
done and material to be furnished under this contract may differ somewhat from these estimates. and
that where the basis for payment under this contract is the unit price method, payment shall be for the
actual amount of such work done and the material furnished.
GC-13
Where payment is based on the unit price method, the Contractor agrees that he will make no claim for
damages, anticipated profits or otherwise on account of any differences which may he found between the
quantities of work actually done, the material actually furnished under this contract and the estimated
quantities contemplated and contained in the proposal; provided, however, that in case the actual quan-
tity of any major item should become as much as 20% more than, or 20% less than the estimated or con-
templated quantity for such items, then either party to this Agreement, upon demand, shall be entitled
to a revised consideration upon the portion of the work above or below 20% of the estimated quantity.
A "Major Item" shall be construed to be any individual bid item incurred in the proposal that has a
total cost equal to or greater than five (5) per cent of the total contract cost, computed on the basis of
the proposal quantities and the contract unit prices.
Any revised consideration is to be determined by agreement between the parties, otherwise by the terms
of this Agreement, as provided under "Extra Work."
5.03 Price of Work
In consideration of the furnishing of all the necessary labor, equipment and material, and the completion
of all work by the Contractor, and on the completion of all work and on the delivery of all material ern-
braced in this Contract in full conformity with the specifications and stipulations herein contained, the
Owner agrees to pay the Contractor the prices set forth in the Proposal hereto attached, which has been
made a part of this contract. The Contractor hereby agrees to receive such prices in full for furnishing all
material and all labor required for the aforesaid work, also for all expense incurred by him, and for well
and truly performing the same and the whole thereof in the manner and according to this Agreement.
5.04 Partial Payments
On or before the 1st day of each month, the Contractor shall submit to the Engineer a statement sho•,ving
the total value of the work performed up to and including the 25th day of the preceding month. The state-
ment shall also include the value of all sound materials delivered on the job site and to be included in the
work all partially completed work whether bid as a lump sum or a unit item which in the opinion of the
Engineer is acceptable. The Engineer shall examine and approve or modify and approve such statement.
The Owner shall then pay the Contractor on or before the 10th day of the current month the total
amount of the approved statement, less 10 per cent of the amount thereof, which 10 per cent shall he
retained until final payment, and further less all previous payments and all further sums that may be
retained by the Owner under the terms of this Agreement. It is understood, however, that in case the
whole work be near to completion and some unexpected and unusual delay occurs due to no fault or
neglect on the part of the Contractor. the Owner may —upon written recommendation of the Engineer —
pay a reasonable and equitable portion of the retained percentage to the Contractor: or the Contractor al
the Owner's option, may be relieved of the obligation to fully complete the work and, thereupon, the
Contractor shall receive payment of the balance due him under the contract subject only to the condi-
tions stated under "Final Payment."
5.05 Use of Completed Portions
The Owner shall have the right to take possession of and use any completed or partially completed por-
tions of the work, notwithstanding the time for completing the entire work or such portions may not
have expired but such taking possession and use shall not be deemed an acceptance of any work not
completed in accordance with the Contract Documents. If such prior use increases the cost of or delays
the work, the Contractor shall be entitled to such extra compensation, or extension of lime, or both, as
the Engineer may determine.
The Contractor shall notify the Engineer when, in the Contractor's opinion. the contract is "substan-
tially completed" and when so notifying the Engineer, the Contractor shall furnish to the Engineer in
writing a detailed list of unfinished work. The Engineer Kill review the Contractor's list of u.^ ..ished
cork and will add thereto such items as the Contractor has failed to include. The "substantial comple-
tion" of the structure or facility shall not excuse the Contractor from performing all of the work under-
taken, whether of a minor or major nature. and thereby completing the structure or facility in act�r-
dance with the Contract Documents.

5.06 Final Completion and Acceptance
Within ten (10) days after the Contractor has given the Engineer written notice that the work has been
completed, or substantially completed, the Engineer and the Owner shall inspect the work and within
said time, if the work be found to be completed in accordance with the Contract Documents, the Engi-
neer shall issue to the Owner and the Contractor his Certificate of Completion, and thereupon it shall be
the duty of the Owner within ten (10) days to issue a Certificate of Acceptance of the work to the Con •
tractor or to advise the Contractor in writing of the reason for non - acceptance.
5.07 Final Payment
Upon the issuance of the Certificate of Completion, the Engineer shall proceed to make final measure-
ments and prepare final statement for the value of all work performed and materials furnished under the
terms of the Agreement and shall certify same to the Owner, who shall pay to the Contractor an or
before the 30th day, and before the 35th day, after the date of the Certificate of Completion, the balance
due the Contractor under the terms of this contract; and said payment shall become due in any event
upon said performance by the Contractor. Neither the Certificate of Acceptance nor the final payment,
nor any provision in the Contract Documents, shall relieve the Contractor of the obligation for fulfill-
ment of any warranty which may be required.
5.08 Payments Withheld
The Owner may, on account of subsequently discovered evidence, withhold or nullify the whole or part
of any certificate to such extent as may be necessary to protect himself from loss on account of:
(a) Defective work not remedied or other obligations hereunder not done.
(b) Claims filed or reasonable evidence indicating probable filing of claims.
1e) Failure of the Contractor to make payments properly to subcontractors or for material or labor.
(d) Damage to another contractor.
(e) Reasonable doubt that the work can be completed for the unpaid balance of the contract amount.
(f) Reasonable indication that the work will not be completed within the contract time.
When the above grounds are removed or the Contractor provides a Surety Bond satisfactory to the
Owner, which will protect the Owner in the amount withheld, payment shall be made for amounts
withheld because of them.
5.09 rlelayed Payments
Should the Owner fail to matte payment to the Contractor of the sum named in any partial or final state-
ment, when payment is due, then the Owner shall pay to the Contractor, in addition to the sum sho as
due by such statement, interest thereon at the rate of 6% per annum, unless otherwise specified, from dace
due as provided under 'partial payments' and 'final payments; until fully paid, which shall fully liquidate
any injury to the contractor growing out of such delay in payment. It is expressly agreed that delay by the
Owner in making payment to the Contractor of the sum named in any partial or final statement shall not
constitute a breach of this contract on the part of the Owner nor an abandonment thereof nor shall it to
any extent or for any time relieve the Contractor of his obligations to fully and completely perform here•
under.

set forth for Extra Work, and any change :n contract
G C•15
In the event. the Contractor shall refuse to execute a Change Order which has been prepared by the
Engineer and executed by the Owner, the Engineer may in writing instruct the Contractor to proceed
with the work as set forth in the Change Order and the Contractor may make claim against the Owner
for Extra Work involved therein, as hereinafter provided.
6.02 Minor Changes
The Engineer may authorize minor changes in the work not inconsistent with the overall intent of the
Contract Documents and not involving an increase in Contract Price. If the Contractor believes that any
minor change or alteration authorized by the Engineer involves Extra Work and entitles him to an in.
crease in the Contract Price, the Contractor shall make written request to the Engineer for a written
Field Order.
In such case, the Contractor by copy of his communication to the Engineer or otherwise in writing shall
advise the Owner of his request to the Engineer for a written Field Order and that work involved may
result in an increase in the Contract Price.
Any request by the Contractor for a change in Contract Price shall be made prior to beginning the work
covered by the proposed change.
6.03 Extra Work
It is agreed that the basis of compensation to the Contractor for work either added or deleted by a
Change Order or for which a claim for Extra Work is made shall be determined by the unit prices upon
which this contract was bid to the extent such work can be fairly classified within the various work item
descriptions and for work items that cannot be so classified by one or more of the following methods:
Method (A)
By agreed unit prices; or
Method (3)
By agreed lump sum; or
Method (C)
If neither Method (A) nor Method (B) be agreed upon before the Extra Work is commenced,
then the Contractor shall be paid the "actual field cost" of the work, plus fifteen (15) percent.
In the event said Extra Work be performed and paid for under Method (C), then the provisions of this
pLragraph shall apply and the "actual field cost" is hereby defined to include the cost to the Contractor
of all workmen, such as foreman, timekeepers, mechanics and laborers, and materials, supplies, trucks,
rentals on machinery and equipment, for the time actually employed or used on such Extra 5Vork, plus
actual equipment, for the time actually employed or used on such Extra Work, plus actual transporta-
tion charges necessarily incurred, together with all power, fuel, lubricants, water and similar operating
expenses, also all necessary incidental expenses incurred directly on account of such Extra Work,
including Social Security, Old Age Benefits and other payroll taxes, and, a rateable proportion of
premiums on Performance and Payment Bonds and Maintenance Bonds, Public Liability and Property
Damage and Workmen's Compensation, and all other insurance as may be required by any law or
ordinance, or directed by the Owner, or by them agreed to. The Engineer may direct the form in which
accounts of the "actual field cost" shall be kept and the records of these accounts shall be made avail-
able to the Engineer. The Engineer or Owner may also specify in writing, before the work commences,
the method of doing the work and the type and kind of machinery and equipment to be used otherwise
these matters shall be determined by the Contractor. Unless otherwise agreed upon, the prices for the
use of machinery and equipment shall be determined by using 100 per cent, unless otherwise specified, of
the latest schedule of Equipment Ownership Expense adopted by the Associated General Contractors of
America Where practicable the terms and prices for the use of machinery and equipment shall be incor-
porated in the Written Extra Work Order. The fifteen (15 t( per cent of the "actual field cost" to be paid
the Contractor shall cover and compensate him for his profit, overhead, general supermtende nce and
field office expense, and all other elements of cost and expense not embraced the "actual field
cost" as herein defined, save that where the Contractor's Camp or Field Office must be maintained pri-

marily on account of such Extra Work; then the cost to maintain and operate the same shall be included
in the "actual field cost."
No claim for Extra Work of any kind will be allowed unless ordered in writing by the Engineer. In case
any orders or instructions, either oral or written, 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 Engineer for 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 therefor, and the
Engineer insists upon its performance, the Contractor shall proceed with the work after making written
request for written order and shall keep an accurate account of the "actual field cost" thereof, as pro-
vided under Method (C). The Contractor will thereby preserve the right to submit the matter of
payment to arbitration, as hereinbelow provided.
6.04 Time of Filing Claims
It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the
Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has
given any directions, order or instruction to which the Contractor desires to take exception. The
Engineer shall reply within thirty (30) days to such written exceptions by the Contractor and render his
final decision in writing. In case the Contractor should appeal from the Engineer's decision, any demand
for arbitration shall be filed with the Engineer and the Owner in writing within ten (10) days after the
date of delivery to Contractor of the Engineer's final decision. It is further agreed that final acceptance
of the work by the Owner and the acceptance by the Contractor of the final payment shall be a bar to
any claims by either party, except claims by Owner for defective work or enforcement of warranties and
except as noted otherwise in the contract documents.
6.05 Arbitration
All questions of dispute under this Agreement shall be submitted to arbitration at the request of either
party to the dispute. The parties may agree upon one arbiter, otherwise, there shall be three, one named
in writing by each party, and the third chosen by the two arbiters so selected; or if the arbiters fail to
select a third within ten (10) days. he shall be chosen by a District Judge serving the County in which
the major portion of the protect is located, unless otherwise specified. Should the party demanding
arbitration fail to name an arbiter within ten (10) days of the demand, his right to arbitrate shall lapse,
and the decision of the Engineer shall be final and binding on him Should the other party fail to choose
an arbiter within ten (10) days, the Engineer shall appoint such arbiter. Should either party refuse or
neglect to supply the arbiters with any papers or information demanded in writing, the arbiters are
empowered by both parties to take ex parte proceedings.
The arbiters shall act with promptness. The decision of any two shall be binding on both parties to the
contract. The decision of the arbiters upon any questions submitted to arbitration under this contract
shall be a condition precedent to any right of legal action. The decision of the arbiter or arbiters may be
filed in court to carry it into effect.
The arbiters, if they deem the case demands it, are authorized to award the party whose contention is
sustained, such sums as they deem proper for the time, expense and trouble incident to the appeal, and
if the appeal was taken without reasonable cause, they may award damages for any delay occasioned
thereby. The arbiters shall fix their own compensation unless otherwise provided 1)y agreement, and
shall assess the cost and charges of the arbitration upon either or both parties. The award of the arbiters
must be made in writing.
7. Abandonment ofi Contract
7.01 Abandonment by Contractor
In case the Contractor should abandon and fail or refuse to resume work within ten (101 days after writ-
ten notification from the Owner, or the Engineer, or if the Contractor fails to comply with the orders of
GC -17
the Engineer, when such orders are onsistent with the Contract Documents, then, and in that case,
where performance and payment bonds exist, the Sureties on these bonds shall be notified in writing and
directed to complete the work, and a copy of said notice shall be delivered to the Contractor.
After receiving said notice of abandonment the Contractor shall not remove from the work any machin-
ery, equipment, tools. materials or supplies then on the job, but the same, together with any materials
and equipment under contract for the work. may be held for use on the work by the Owner or the Surety
on the performance bond. or another contractor us completion of the work: and the Contractor shall not
receive any rental or credit therefor 'except when used in connection with Extra Work, where credit shall
be allowed as provided for under Section 6, Extra Work and Claims) • it being understood that the use of
such equipment and materials will ultimately reduce the cost to complete the work and be reflected in
the final settlement.
Where there is no performance bond provided or in case the Surety should fail to commence compliance
with the notice for completion hereinbefore provided for, within ten (10) days after service of such notice,
then the Owner may provide for completion of the work in either of the following elective manners:
(1) The Owner may thereupon employ such force of men and use such machinery, equipment, tools,
materials and supplies as said Owner may deem necessary to complete the work and charge
the expense of such labor, machinery. equipment. tools. materials and supplies to said Con-
tractor, and expense so charged shall be deducted and paid by the Owner out of such moneys
as may be due, or that may thereafter at any time become due to the Contractor under and
by virtue of this Agreement. Incase such expense is less than the sum which would have
been payable under this contract, if the same had been completed by the Contractor, then
said Contractor shall receive the difference In case such expense is greater than the sum
which would have been payable under this contract, if the same had been completed by said
Contractor, then the Contractor and /or his Surety shall pay the amount of such excess to the
Owner, or
(2) The Owner under competitive bids, taken after notice published as required by law, may let the
• contract for the completion of the work under substantially the same terms and conditions
which are provided in this contract. In case there is any increase in cost to the Owner under
the new contract as compared to what would have been the cost under this contract, such
increase shall be charged to the Contractor and the Surety shall be and remain bound there-
for. However, should the cost to complete any such contract prove to be less than would
have been the cost to complete under this contract, the Contractor and /or his Surety shall
be credited therewith. •
When the work shall have been substantially completed the Contractor and his Surety shall be _so noti-
fied and Certificates of Completion and Acceptance. as provided in Paragraph 5.06 hereinabove, shall be -
issued. A complete itemized statement of the contract accounts, certified to by the Engineer as being
correct. shall then be prepared and delivered to the Contractor and his Surety. whereupon the Con-
tractor and /or his Surety, or the Owner as the case may be. shall pay the balance due as reflected by
said statement, within fifteen (151 days after the date of such Certificate of Completion.
In the event the statement of accounts shows that the cost to complete the is less than that which
would have been the cost to the Owner had the work been completed by the Contractor under the terms
of this contract; or when'the Contractor and!or his Surety shall pay the balance shown to be due by
them to the owner. then all machinery. equipment. tools. materials or supplies left on the site of the
work shall be turned over to the Contractor and: or his Surety. Should the cost to complete the work
exceed the contract price. and the Contractor and or his-Surety fail to pay the amount due the Owner

After mailing, or other giving of such notice, such property shall be held at the risk of the Contractor
and his Surety subject only to the duty of the Owner to exercise ordinary care'to protect such property.
After fifteen 1151 days from the date of said notice the Owner mac sell such machinery. equipment.

Owner may elect. The Owner shall release any machinery, equipment, tools, materials. or supplies, which
remain on the work, and belong to persons other than the Contractor or his Surety, to their proper
owners. The books on all operations provided herein shall be opened to the Contractor and his Surety.
7.02 Abandonment by Owner
In case the Owner shall fail to comply with the terms of this contract, and should fail to comply with
said terms within ten (10) days after written notification by the Contractor, then the Contractor may
suspend or wholly abandon the work. and may remove therefrom all machinery, tools and equipment.
and all materials on the site of work that have not been included in payments to the Contractor and
have not been wrought into the work. And thereupon the Engineer shall make an estimate of the total
amount earned by the Contractor, which estimate shall include the -value of all work actually completed
by said Contractor (at the prices stated in the attached proposal where unit prices are used), the value of
all partially completed work at a fair and equitable price, and the amount of all Extra Work performed
at the prices agreed upon, or provided for by the terms of this contract, and a reasonable sum to cover
the cost of any provisions made by the Contractor to carry the whole work to completion and which
cannot be utilized. The Engineer shall then make a final statement of the balance due the Contractor by
deducting from the above estimate all previous payments by the Owner and all other sums that may be
retained by the Owner under the terms of this Agreement and shall certify same to the Owner who shall
pay to the Contractor on or before thirty (30) days after the date of the notification by the Contractor
the balance shown by said final statement as due the Contractor, under the terms of this Agreement.

340.8 Construction Methods
It shall be the responsibility of the Contractor to produce, transport, place and compact the specified paving mixture in accor-
dance with these specifications and provide a safe environment to enable inspection forces to take samples and check the ptent.
Prior to placing HMAC, the base shall be proof rolled and any soft spots repaired and the area proof rolled again.
The asphaltic mixture, when placed with a motor grader for leveling, shall not be placed when air temperature is below 50 F and
falling. The air temperature shall be taken in the shade away from artificial heat. Mat thickness of 11/2 inches and less shall not be
placed when the temperature of the surface on which the mat is to be placed is below 50 F.
All asphaltic mixture, except that described above for leveling, shall be placed with a spreading and finishing machine. If, after
being discharged from the mixer and prior to placing, the temperature of the asphaltic mixture is 50 F or more below the tempera-
ture established, all or any part of the load may be rejected and payment will not be made for the rejected material. Any material
placed which is too cool to compact properly shall be removed and replaced with material which meets the specifications.
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. The compacted thickness of the asphaltic concrete courses shall be as
indicated. Where the thickness of the surface course is specified to be more than 2 inches, the work shall be accomplished in
equal lifts, unless otherwise indicated. When the surface is to be constructed in stages and traffic is permitted on the initial layer,
each layer shall be not less than 1 inch.
The final lift of HMAC shall not be placed adjacent to an existing cured rounded edge asphalt surface until the existing surface

provided as required by the Engineer.
340.5 Stockpiling Aggregates
•
Prior to stockpiling of aggregates, the area shall be cleaned of trash, weeds and grass and be relatively smooth. Aggregates shall
be stockpiled in such a manner as to prevent mixing of one aggregate with another. Coarse aggregates for Type B and Type C
shall be separated into at least two stockpiles of different gradation, such as a large coarse aggregate and a small coarse aeare-
gate stockpile and such that the grading requirements of the specified type will be met when the piles are combined in the
asphaltic mixture. Suitable equipment of acceptable size shall be furnished by the Contractor to load out the stockpiles such that
segregation of the aggregates does not occur.

If a prime coat is indicated, it shall be applied conforming to Item No. 306, "Prime Coat ", except the acpiicat,en
temperature shall be as provided above. The asphaltic concrete shall not be applied on a previously primed flexicle
base until the primed base has cured to the satisfaction of the Engineer.
(2) Tack Coat
If a tack coat is indicated, it shall be applied conforming to Item No. 307, "Tack Coat" Before the aspha'tio m•xtore 0
placed, the surface upon which the tack coat is to be placed shall be cleaned thoroughly to the sa:,stact.cn of the
Engineer. The surface shall be given a uniform application of tack coat using asphaltic matena s of tnis spec:,:catan.
This tack coat shall be applied, as directed by the Engineer. Where the mixture w.11 adhere to the surface cf which n
is to be placed without the use of a tack coat, the lack coat may be eliminated by the Eng:neer. 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 light pneumatic tire roller when directed by the
Engineer.
(3) Compacting
The mix shall be compressed thoroughly and uniformly compacted immediately after placing to the required ders,ty.
All compaction rolling shall be complete before the mat cools below 175 F. Minor polishing roling may De .rrcertaken
on the mat below the above temperature.
All rollers must be in good mechanical condition. Necessary precautions shall be taken to prevert tra cropoi 'rg of
gasoline, ail, grease or other foreign matter on the pavement, either when the rollers are in operat.on cr who
standing.
It is the intent of this specification that the material be placed and compacted to a minimum of 92.5 percent of the
maximum theoretical density as determined by SDHPT Tex - 227 -F. The Engineer will secure 6 inch core samples cr
sections of completed asphaltic pavement lifts for approximately every 2,000 scuare yards or part :hereof, CT
asphaltic concrete pavement placed. The in place density at the sampled locations shall be determ nod by t`e
lowing equation:
340 04/17,86 Page 6
Percent in place Density = GA x 100
T
Where GA = Bulk soec:fic gravity of core when tested in accordance with Tex -207 -F
GT = Maximum theoretical specific gravity of combined cores when tested in accordance with Tex -227 -F
The Contractor shall patch the surface where specimens are taken with no extra payment being made for this wort.
The Engineer will remove the asphaltic concrete pavement specimen on the day following placement or as soon as
practicable thereafter. Cther methods of determining in place density which correlate satisfactorily with those results
obtained by cores or sections may be used.
The initial sampling and testing of in place asphalt concrete will be at no cost to the Contractor, except for the cost 0;
material and restoration of damage by testing. Retesting expense will conform to Section, 00344, •Test.ng Laccra-
tory Services ".
(4) Surface Tests
The surface of the pavement, after compaction, shall be smooth and true to the established line, grade and ur0_s
section, and when tested with a 10 foot straightedge placed parallel to the centerl,ne of the roadxay or tested by
other equivalent and acceptable means, except as provided herein, the maximum deviation shall not exceed / incn
in 10 feet and any point in the surface not meeting this requirement shall be corrected. The completed surface shall
meet the approval of the Engineer for riding surface, finish and appearance.
(5) Opening to Traffic
The pavement shall be opened to traffic as soon as possible after temporary pavement markings cr perma^.e1f
pavement markings are in place as indicated and the Engineer concurs to the opening. The Contractor's attention is
directed to the fact that all construction traffic allowed on pavement open to the public will be seolect ;o tre C::y
Ordinances and State Laws governing traffic on streets and highways.
Surface raveling, cracking, segregation and other defects shall be corrected at the Contractor's expense as d recited
by the Engineer. Traffic control expense for undertaking the repairs will be at the Contractor's expense.

340.9 Acceptance Plan
(1) General
The surface testing shall be completed prior to the use of pay adjustment factors for acceptance of gradation, as-
phalt content, stability, in place density and pavement thickness. The pay adjustments will be based upon the resu:ts
of tests performed on samples taken in a random manner. Pay adjustment for private development work shall con-
form to Item No. 1804, "General Obligations and Responsibility of the Owner ".
(a) Sampling
The Engineer will determine the sampling schedules for random testing in accordance with SDHPT Test
Method Tex - 225 -F. Samples will be taken at the plant or on the project site, as determined by the Engineer.
The Engineer may require that either cores or sections of asphaltic pavement be taken at locations selected
by the Engineer.
(b) Testing
Determination of acceptability will be based on tests performed by the City or its laboratory. However, truck
loads of the asphaltic mixture that are visually inspected by the Engineer and can reasonably be expected not
to meet specification requirements, such as a mixture containing segregated material, low mixture tempera-
ture, a deficiency or excess of asphalt, or otherwise unsuitable for placing on the roadway shall not be used.
Any mixtures containing segregated areas, deficiency or excess of asphalt or otherwise unsuitable that is
placed on the roadway shall be removed and replaced with satisfactory material at the Contractor's expense.
' Acceptability will be based on the mean of the job values from the City tests of the project materials.
(2) Gradation and Asphalt Content
' The acceptability of mixture gradation and asphalt content will be based on the mean of a minimum of 3 tests taken
by the City's laboratory.
If the mean value of acceptance tests of the project, for a particular sieve or sieves or for asphalt content deviates
1 ° from the project design by more than the tolerances shown and the Engineer determines that the material need not
be removed and replaced, the project may be accepted at a reduced Contract Unit Price as follows:
