Any bid may be withdrawn prior to the above scheduled time for the opening of bids. Any bid received after the time and date specified will be returned unopened.
2. Method of Award
The Town of Groton intends to award the contract to the lowest responsible bidder. The Town reserves the right to reject any and all bids and to award each contract to the bidder who is most responsive to the interests of the Town. If the lowest base bid submitted by a responsible bidder does not exceed the amount of funds then estimated by the Owner as available to finance the contract, the contract will be awarded on the base bid only. If such bid exceeds such amount, the Owner will reject all bids.
3. Bid Schedule
Bids must be made on these forms and returned intact. Bidders will state both in writing and in figures, in ink or typewritten, the proposed price for each separate item of the work called for in the bid schedule, by which prices will be compared. If any price is omitted, the blank shall be filled with the highest price named by any bidder for that item or the bid may be rejected. Alterations and erasures must be initialed by the signer.
4. Arithmetic Discrepancies
A. For the purpose of initial evaluation of bids, the following will be utilized in resolving arithmetic discrepancies found on the face of the bidding schedule as submitted by bidders:
1. Obviously misplaced decimal points will be corrected. 2. In case of discrepancy between unit price and extended price, the
unit price will govern. 3. Apparent errors in extension of unit prices will be corrected.
6
4. Apparent errors in addition of lump sum and extended prices will
be corrected.
B. For the purpose of bid evaluation, the Town will proceed on the assumption that the bidder intends his bid to be evaluated on the basis of the unit prices, extensions, and totals arrived at by resolution of arithmetic discrepancies as provided above and the bid will be so reflected on the abstract of bids.
5. Bid Security
If the total amount of the bid submitted exceeds $50,000, or if the bid contains any add alternates and the combination of the base bid plus all add alternates exceeds $50,000, then the bid must be accompanied by a CERTIFIED CHECK or a BID BOND, signed by a responsible Surety, in the amount of 10% of the total amount of the tendered bid and made payable to the order of the Town of Groton. All bid checks or bonds, except those of the lower three (3) bidders will be returned within ten (10) days of the opening of bids.

No bidder may withdraw his bid within 60 days after the actual date of the opening thereof.
Should there be reasons why the CONTRACT cannot be awarded within the specified period, the time may be extended by mutual agreement between the OWNER and the BIDDER.

This Bond will secure payment for applicable taxes payable to the State related to this Project. The State will issue a Certificate of Compliance once an acceptable bond has been submitted by the Non-Resident Contractor. This Certificate of Compliance must be provided by the Contractor to the Town prior to the release of the first progress payment under the Contract, or the Town must remit 5% of the total contract value directly to the State. This 5% is in addition to the Project retainage.

Bidders, if requested, must be able to present evidence satisfactory to the Director of Public Works that they have been regularly engaged in the business of constructing such work as they propose to execute, and that they are fully prepared with the necessary capital, materials, and equipment to conduct the work to be contracted for, and to begin it promptly when ordered.
Prior to submitting his bid, the bidder must inspect the site and thoroughly read all plans, specifications and bid and contract documents. The failure or omission of any bidder to examine any form, instrument or document and to thoroughly examine the site shall in no way relieve any bidder from any obligations in respect to his bid.
13. Damages for Failure to Enter into Contract
The party to whom the CONTRACT is awarded will be required to execute the CONTRACT within thirty (30) calendar days from the date when Notice of Award is
10
delivered to the BIDDER. In case of failure of the BIDDER to execute the CONTRACT, the OWNER may at his option, consider the BIDDER in default, in which case the bid security accompanying the proposal shall become the property of the OWNER as liquidated damages and not as a penalty.
14. Execution of Contract and Notice to Proceed
The OWNER within twenty (20) days of receipt of acceptable PERFORMANCE BOND, PAYMENT BOND and CONTRACT signed by the party to whom the CONTRACT was awarded shall sign the CONTRACT and return to such party an executed duplicate of the CONTRACT. Should the OWNER not execute the CONTRACT within such period, the BIDDER may by written notice withdraw his signed CONTRACT. Such notice of withdrawal shall be effective upon receipt of the notice by the OWNER.
The Notice to Proceed shall be issued within ten (10) days of the execution of the CONTRACT by the OWNER. Should there be reasons why the Notice to Proceed cannot be issued within such period, the time may be extended by mutual agreement between the OWNER and the CONTRACTOR. If the Notice to Proceed has not been issued within the ten (10) day period or within the period mutually agreed upon, the CONTRACTOR may terminate the CONTRACT, whereupon it shall become null and void and all rights and obligations created thereunder shall be extinguished.
15. Time of Completion and Liquidated Damages
BIDDER must agree to commence work on or before a date to be specified in a written Notice to Proceed from the OWNER and to fully complete the project within 30 consecutive calendar days thereafter. Bidder must agree also to pay as liquidated damages, the sum of $200.00 for each consecutive calendar day thereafter as hereinafter provided in the GENERAL CONDITIONS.
It is hereby understood and mutually agreed, by and between the CONTRACTOR and the OWNER, that the date of beginning and the time for completion during the normal working hours as specified in the General Conditions of the work to be done hereunder are essential conditions of this CONTRACT; and it is further mutually understood and agreed that the work embraced in this CONTRACT shall be commenced on a date to be specified in the "Notice to Proceed".
The CONTRACTOR agrees that said work shall be prosecuted regularly, diligently, and uninterruptedly at such rate of progress as will insure full completion thereof within the time specified. It is expressly understood and agreed, by and between the CONTRACTOR and the OWNER, that the time for the completion of the work described herein is a reasonable time for the completion of same, taking into consideration the average climatic range and usual industrial conditions prevailing in this locality.
If the said CONTRACTOR shall neglect, fail or refuse to complete the work within the time herein specified, or any proper extensions thereof granted by the OWNER, then the CONTRACTOR does hereby agree, as a part consideration for the awarding of this
11
CONTRACT, to pay to the OWNER the amount specified in the Information for Bidders, not as a penalty but as liquidated damages for such breach of CONTRACT as hereinafter set forth, for each and every calendar day that the CONTRACTOR shall be in default after the time stipulated in the CONTRACT for completion of the work.
The said amount is fixed and agreed upon by and between the CONTRACTOR and the OWNER because of the impracticability and extreme difficulty of fixing and ascertaining the actual damages the OWNER would in such event sustain, and said amount is agreed to be the amount of damages which the OWNER would sustain and said amount shall be retained from time to time by the OWNER from current periodic estimates.
It is further agreed that time is of the essence of each and every portion of this CONTRACT and of the specifications wherein a definite and certain length of time is fixed for the performance of any act whatsoever; and where under the CONTRACT an additional time is allowed for the completion of any work, the new time limit fixed by such extension shall be of the essence of this CONTRACT. The CONTRACTOR shall not be in default when the delay in completion of the work is due:
A. To any preference, priority or allocation order duly issued by the State or Federal
Government B. To unforeseeable cause beyond the control and without the fault or negligence of
the CONTRACTOR, including, but not limited to, acts of God, or of the public enemy, acts of the OWNER, acts of another contractor in the performance of a contract with the OWNER, fires, floods, epidemics, quarantine restrictions, strikes, freight embargoes and severe weather. The CONTRACTOR shall, within ten (10) days from the beginning of any such delay, unless the OWNER shall grant a further period of time prior to the date of final settlement of the CONTRACT, notify the OWNER, in writing, of the causes of the delay. The Owner shall ascertain the facts and extent of the delay and notify the CONTRACTOR within a reasonable time of its decision in the matter.
16. Addenda and Interpretations All questions about the meaning or intent of the Contract Documents are to be directed to the Owner. Interpretations or clarifications considered necessary by the Owner in response to such questions will be issued by Addenda mailed or delivered to all parties recorded by the Owner as having received the Bidding Documents. Questions received less than seven days prior to the date for opening of Bids may not be answered. Only questions answered by formal written Addenda will be binding. Oral and other interpretations or clarifications will be without legal effect.
Addenda will be issued to modify the Bidding Documents as deemed advisable by the Owner.
12

22. Site Investigation and Conditions Affecting the Work
Arrangements to visit the site may be made by calling the Public Works Department Engineering Division, (860) 448-4083, Monday through Friday, 8:30 a.m. to 3:30 p.m.
A. The Contractor acknowledges that it has taken steps reasonably necessary to
ascertain the nature and location of the work, and that it has investigated and satisfied itself as to the general and local conditions which can affect the work or its cost, including but not limited to:
1. Conditions bearing upon transportation, disposal, handling, and storage of
materials; 2. The availability of labor, water, electric power, and roads; 3. Uncertainties of weather, river stages, tides, or similar physical conditions
at the site; 4. The conformation and conditions of the ground; and 5. The character of equipment and facilities needed preliminary to and during
work performance.
B. The Contractor also acknowledges that it has satisfied itself as to the character, quality, and quantity of surface and subsurface materials or obstacles to be encountered insofar as this information is reasonably ascertainable from an inspection of the site, including all exploratory work done by the Town, as well from the drawings and specifications made a part of this contract. Any failure of the Contractor to take the actions described and acknowledged in this paragraph will not relieve the Contractor from responsibility for estimating properly the difficulty and cost of successfully performing the work, or for proceeding to successfully perform the work without additional expense to the Town.
C. The Town assumes no responsibility for any conclusions or interpretations made by the Contractor based on the information made available by the Town. Nor does the Town assume responsibility for any understanding reached or representation made concerning conditions, which can affect the work by any of
14
its officers or agents before the execution of this contract, unless that understanding or representation is expressly stated in this Contract.
D. The Contract Documents contain the provisions required for the construction of the project. Information obtained from an officer, agent or employee of the OWNER or any other person shall not affect the risks or obligations assumed by the CONTRACTOR or relieve him from fulfilling any of the conditions of the CONTRACT.
23. Permits
The Contractor must obtain all necessary construction and building permits; however, the fee for any permits issued by the Town of Groton shall be waived.
24. Work Area
Construction will be confined to the immediate work area only. Trespass on property other than Town property or easements acquired by the Town for the project will be by written permission of the property owner only.
25. Change Orders
Any deviations from, additions to, or deductions from either scope of work or contract price shall be submitted by the Contractor to the Town in the form of a contract change order. The Director of Public Works must approve this contract change order before said deviations, additions, or deductions shall be enacted.
Further, all changes in scope of work involving unit price items shall be governed by the unit price indicated by the Contractor on the Base Bid Form.
26. Wages
Bidder is directed to Paragraph 45 of the General Conditions for wage rate scales and legislation applicable to this contract.
27. Unbalanced Bids An unbalanced bid is one in which the contractor’s unit prices are:
a. Significantly higher or lower than the Engineer’s estimate.
b. “Front loaded” so contractor receives a disproportionate payment for work done during the early stages of a project.
c. Token bid prices (i.e. penny unit bids).
While it is often impossible to designate precisely the dividing line between a balanced bid and an unbalanced bid, contractors should be aware that the Department may regard the
15
unbalancing of a bid as so extreme, undeniable, or detrimental to the interests of the Town that it may question the contractor about the apparent unbalancing of the bid proposal, and, if the contractor cannot provide a satisfactory explanation of the apparent unbalancing, and if the Department’s assessment of the risk to the Town is unacceptable, reject the bid as nonresponsive. 28. OSHA Violations In accordance with Connecticut General Statute Section 31-57b, no contract shall be
awarded to a bidder if it is determined that the bidder (person or firm) has been cited for three (3) or more willful or serious violations of any occupational safety and health act or of any standard, order or regulation promulgated pursuant to such act during the three (3) year period preceding the date of bid opening.
29. Local Vendor Preference The Town of Groton has adopted a policy of providing preference to selecting Local
Vendors as outlined in this section. The term “Local Vendor” as used in this section shall mean, and be used interchangeably with, “Bidder” and “Contractor”.
A. Definition: The term “Local Vendor” shall mean a company, firm, LLC, partnership,
sole proprietorship or similar business with its principal place of business located within the Town of Groton. A business shall not be considered a local vendor unless satisfactory evidence has been submitted with the bid that clearly establishes that it has a bona fide principal place of business, including branches or satellite offices, in the Town of Groton. Such documentation shall include evidence of ownership such as real estate and personal property bills, a lease agreement for the real estate from which the principal place of business operates, copies of deeds, or copies of paid real estate and personal property bills.
B. Application: To be considered, and be given preference as a local vendor, the bidder
must complete and submit with their bid, a local vendor registration affidavit of eligibility (included hereinafter) together with copies of any of the documents listed above in paragraph A. A local vendor registration affidavit of eligibility submitted after bids are opened will not be considered.
C. Implementation: If the total bid amount, together with any add or deduct alternates the
Town wishes to accept, submitted by a qualified responsive Local Vendor is not more than five percent (5%) higher than the lowest bid, then the Town has the right to award the contract to the local vendor provided he agrees to match the lowest bid.
In the instance of two or more Local Vendors being within the 5% threshold, then the qualified responsive local vendor with the lowest actual bid will be given the first opportunity to match the low bid. For bids involving unit prices, and when the qualified responsive local vendor agrees to match the low total bid amount, he must also submit updated individual unit prices
16
showing the total amount to meet the low bid. The Town of Groton reserves the right to approve or disapprove which unit prices are used to net the total bid amount.
D. Notification: When a local vendor meets the criteria for submitting a successful bid
and has provided all of the required documentation, a letter signed by the Public Works Director will be sent to the local vendor. The letter will notify the local vendor that they have met all of the criteria of this provision and will formally request that they respond in writing to the Town within five (5) business days that they are willing to match the lowest price bid. In the case of bids with unit prices, the local vendor must also include a revised list of unit prices. Once the local vendor has agreed to match the low bid and all other conditions of a successful bid have been met, the contract will be awarded to the local vendor.
E. Exemptions: Any bid made under the following are exempt from this section:
a. Projects utilizing any Federal or State of Connecticut funds or grants b. Projects utilizing any special grant that stipulates the award must be made
to the lowest qualified bidder

22. General Guaranty

deletions or modifications without invalidating the CONTRACT.
G. The OWNER shall have the right to take possession of and use any completed or partially completed portions of the work, not withstanding that 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 completion of uncompleted work or causes refinishing of completed work, the CONTRACTOR shall be entitled to such extra compensation, or extension of time or both, as the OWNER may determine.
45. Wage Rates
It has been estimated that the cost of this project is less than $100,000.00, and under Section 31-53 of the State Statutes, as amended, State Prevailing Wage Rates do not apply. For this reason, State Wage Rates are not included.
However, should a Contractor's bid exceed the $100,000.00 threshold, it shall be incumbent upon the Contractor to include the applicable prevailing wage rates in the submittal of the bid. In the case where add alternates are part of the bid, and where acceptance of any alternates would cause the contract sum to exceed the $100,000 threshold, then the price of the alternate shall include the applicable prevailing wage rate for the entire project.
46. Contract Bid Breakdown (Lump Sum)
The Contractor shall furnish a breakdown of each lump sum bid within 10 days after date of award of contract. Partial payments will be based on this breakdown. The Contractor's breakdown will be reviewed by the OWNER to insure that costs are proportioned properly between early and late pay items. Any unbalanced items or other discrepancies will be revised by the OWNER and the approved breakdown will be utilized as a basis for progress payment to the Contractor.
47. Hours of Work
Any work necessary to be performed after regular working hours, on Sundays or Legal Holidays, shall be performed without additional expense to the Owner.

48. Waste Disposal
The Contractor shall be responsible for the cost and legal disposal of all construction debris, municipal solid waste, stumps, and excess materials.

2. Imperative Language is used generally in the Specifications.
Requirements expressed imperatively are to be performed by the
Contractor. At certain locations in the text, for clarity, subjective language
is used to describe responsibilities, which must be fulfilled indirectly by
the Contractor, or by others when so noted. The words "shall be" shall be
included by inference where a colon (:) is used within sentences or
phrases.
C. Assignment of Specialists: The Specification requires that certain specific
construction activities shall be performed by specialists who are recognized
experts in the operations to be performed. The specialists must be engaged for
those activities, and the assignments are requirements over which the Contractor
has no choice or option. Nevertheless, the ultimate responsibility remains with
the Contractor.
1. This requirement shall not be interpreted to conflict with enforcement of
building codes and similar regulations governing the Work. It is
also not intended to interfere with local trade union jurisdictional
settlements and similar conventions.
2. Trades: Use of titles such as "carpentry" is not intended to imply that
certain construction activities must be performed by accredited or
unionized individuals of a corresponding generic name, such as
"carpenter".
It also does not imply that requirements specified apply exclusively to
tradepersons of the corresponding generic name.
D. Graphic Legends, Graphic Symbols and Abbreviations: As used on the Drawings,
are generally those recognized in the construction industry for the purposes
indicated.
01070/3-4
E. Mechanical/Electrical Drawings: Graphic symbols used on mechanical and
electrical Drawings are generally aligned with symbols recommended by
ASHRAE. Where appropriate, they are supplemented by more specific
symbols recommended by technical associations including ASME, ASPE, IEEE
and similar organizations. Refer instances of uncertainty to the Engineer for
clarification before proceeding.
1.04 INDUSTRY STANDARDS
A. Applicable standards of construction industry have same force and effect and are
made a part of contract documents by reference as if copied directly into
contract documents, or as if published copies were bound herewith.
B. Reference standards (referenced directly in contract documents or by governing
regulations) take precedence over unreferenced standards, which are recognized in
industry as applicable to the work.
C. Unreferenced standards recognized in the construction industry are hereby
defined, except as otherwise limited in contract documents, to have direct
applicability to the work, and will be so enforced for performance of the work.
D. Publication Dates: Except as otherwise indicated, where compliance with an
industry standard is required, comply with the latest edition and revisions thereof,
if any, in effect as of date of execution of the contract.
E. Copies of Standards: Provide where needed for proper performance of the work;
obtain directly from publication sources.
F. Abbreviations and Names: Where acronyms or abbreviations are used in
specifications or other contract documents, they are defined to mean the industry-
recognized name of trade associations, standards generating organization,
governing authority or other entity applicable to context of text provision. Refer
to "Encyclopedia of Associations", published by Gale Research Company,
available in large libraries.

A. Federal Highway Administration, Manual on Uniform Traffic Control Devices
(MUTCD), Part VI.
1.04 TRAFFIC DIRECTORS
A. Traffic Directors are responsible for human safety and make the greatest number
of public contacts of all construction personnel. It is important that qualified
personnel be selected. A Traffic Director shall possess the following minimum
qualifications:
1. Average Intelligence.
2. Good physical condition, including sight and hearing.
3. Mental alertness.
4. Courteous but firm manner.
5. Neat appearance.
6. Sense of responsibility for safety of public and crew.
B. The use of orange clothing such as a vest, shirt, or jacket shall be required for
Traffic Directors. For nighttime conditions, similar outside garments shall be
reflectorized.
C. Traffic Directors are provided at work sites to stop traffic intermittently as
necessitated by work progress or to maintain continuous traffic past a work site at
reduced speeds to help protect the work crew. For both of these functions, the
Traffic Director must, at all times, be clearly visible to approaching traffic for a
distance sufficient to permit proper response by the motorist to the flagging
instructions, and to permit traffic to reduce speed before entering the work site.
01571/1-5
In positioning Traffic Directors, consideration must be given to maintaining color
contrast between the Traffic Director's protective garments and his background.
1.05 MEASUREMENT AND PAYMENT
A. Measurement
1. Traffic Directors shall be measured by the number of man hours worked at
the work site for each Traffic Director.
2. To be considered for payment under this section, the designated Traffic
Director shall have no other duties except those described by this section.
B. Payment
1. Traffic Directors shall be paid for at the stipulated contract unit price for
"Traffic Directors", which price shall include all materials, tools,
equipment and labor required to perform the safe direction of traffic
throughout the site.
2. The stipulated unit price shall include full compensation and any other
cost or liability incidental thereto for furnishing the Traffic Directors.
3. Uniformed Police Officers, when required, shall be paid directly by the
Town.
PART 2 PRODUCTS
2.01 FLAGS
A. Flags used for signaling purposes shall be a minimum of 24 by 24 inches in size,
made of a good grade of red material securely fastened to a staff approximately 3
feet in length. The free edge should be weighted to insure that the flag will hang
vertically, even in heavy winds.
2.02 PADDLES
A. Sign paddles should be at least 18 inches wide with letters at least 6 inches high.
A rigid handle shall be provided. (A 6' handle (staff) is recommended). This
combination sign may be fabricated from sheet metal or other light semi-rigid
material. The background of the "STOP" face shall be red with white letters and
border. The background of the "SLOW" shall be orange with black letters and
border. When used at night the "STOP" face shall be reflectorized red with white
reflectorized letters and border, and the "SLOW" face shall be reflectorized
orange with black letters and border.
01571/2-5
PART 3 EXECUTION
3.01 FLAGGING
A. The following methods of signaling with a flag shall be used:
1. To Stop Traffic: The Traffic Director shall face traffic and extend the
flag horizontally across the traffic lane in a stationary position so that the
full area of the flag is visible hanging below the staff. For greater
emphasis, the free arm may be raised with the palm toward approaching
traffic.
2. When it is Safe for Traffic to Proceed: The Traffic Director shall stand
parallel to the traffic movement, and with flag and arm lowered from view
of the driver, motion traffic ahead with his free arm. Flags shall not be
used to signal traffic to proceed.
3. Where it is Desired to Alert or Slow Traffic: Where it is desired to alert
or slow traffic by means of flagging, the Traffic Director shall face traffic
and slowly wave the flag in a sweeping motion of the extended arm from
the shoulder level to straight down without raising the arm above a
horizontal position.
B. If a sign paddle is used, it shall be held in a stationary position with the arm
extended horizontally away from the body. For added emphasis, the Traffic
Director may slowly raise and lower his free hand with the palm down.
C. Lights approved by the Director of Public Works, or reflectorized sign paddles or
reflectorized flags, shall be used to flag traffic at night. Daytime flagging
procedures shall be followed whenever such lights, paddles or flags are used at
night.
3.02 TRAFFIC DIRECTORS STATIONS
A. Traffic Directors stations shall be located far enough in advance of the work site
so that approaching traffic will have sufficient distance to reduce speed before
entering the project. This distance is related to approach speed and physical
conditions at the site, however, in no case will the distance be greater than 200 to
300 feet between stations.
01571/3-5
B. The Traffic Directors shall stand either on the shoulder adjacent to the traffic he is
controlling or in the barricaded lane. At a "spot" obstruction he may have to stand
on the shoulder opposite the barricaded section to operate effectively. Under no
circumstances should he stand in the lane being used by moving traffic. He should
be clearly visible to approaching traffic at all times. For this reason, he should
stand alone, never permitting a group of workmen to congregate around him. He
should be stationed sufficiently in advance of the work force to warn them of
approaching danger, such as out-of-control vehicles.
C. Traffic Directors stations shall be adequately protected and preceded by proper
advance warning signs. At night, flagmen stations shall be adequately
illuminated.
D. At short construction and maintenance lane closures where adequate sight
distance is available for the safe handling of traffic, the use of one Traffic Director
may be sufficient.
3.03 ONE-WAY TRAFFIC CONTROL
A. Where a one-way lane section is of any length, there shall be some means of
coordinating movements at each end so that vehicles are not simultaneously
moving in opposite directions in the section and so that delays are not excessive at
either end.
B. Control points at each end of the route should be chosen so as to permit easy
passing of opposing lines of vehicles.
C. Alternate one-way traffic control shall be accomplished by one of the following
means:
1. Traffic Director control, one at each end, using hand signals.
2. Traffic Director control, using hand-held radios.
D. Where the one-lane section is short enough so that each end is visible from the
other end, traffic may be controlled by means of a Traffic Director at each end of
the section. One of the two should be designated as the Chief Traffic Director for
purposes of coordinating movement. They should be able to communicate with
each other verbally or by means of signals. These signals should not be such as to
be mistaken for flagging signals.
01571/4-5
E. Where the end of a one-lane section is not visible from the other end, the Traffic
Director shall maintain contact by means of hand-held radios. So that a Traffic
Director may know when to allow traffic to proceed into the section, the last
vehicle from the opposite direction can be identified by description or license.
3.04 COORDINATION
A. If a Traffic Direction Service is used, the Contractor shall make all necessary
arrangements and coordinate the need for traffic control before the service is
required. The Contractor shall identify the number of personnel required and the
time to report.
3.05 USE OF POLICE
A. During certain times throughout the construction, and as determined by the Chief
of Police or the Director of Public Works, Police Officers may be assigned to the
construction site. These Officers will be assigned during period of heavy traffic or
at intersection of major roads. The Police Officer will be in charge of traffic
control at these sites. The Traffic Directors will augment the Police Officers.
Coordination of the assignment of the Officers will occur between the Engineer
and the Contractor.

vibrators, and/or vibratory or 2 Ton steel-wheeled static rollers before additional
lifts are placed.
E. If necessary to ensure proper compaction by rolling, the material shall first be wet
by sprinkling. However, no compaction by tamping or rolling shall be done when
the material is too wet either from rain or too great an application of water to be
compacted properly. At such times, the work will be suspended until the
previously placed and new materials have dried out sufficiently to permit proper
compacting, or such other precautions shall be taken as may be necessary to
obtain proper compaction.
F. Care shall be taken that stones and lumps do not become nested and that all voids
between stones shall be completely filled with fine material.

and replaced with satisfactory material.
H. In areas where, because of physical limitations, it is impractical to operate paving
equipment, the Engineer may permit use of other type spreaders or the mixture may
be spread and screeded by hand.
1. When hand-spreading is permitted, upon arrival, the mixture shall be
dumped on approved steel dump sheets outside of the area on which it is to
be spread, and shall then be immediately distributed into place by means of
suitable shovels and other tools, and spread with metal lutes in a uniformly
loose layer of such depth as will result in a completed pavement having the
designed depth. Any deviation from standard crown or section shall be
immediately remedied by placing the additional material or removing
surplus as directed.
I. Contact surfaces of curbing, gutters, manholes, etc., shall be painted with a thin
uniform tack coat just before the mixture is placed against them. Such a tack coat
shall not be paid for.
J. A very light, web-like tack coat shall be applied to the entire pavement base before
paving the surface course if the base has been in place longer than five calendar
days. Emulsions for tack coat shall be diluted 50/50 with water and shall not be
heated in excess of 160° F. Care must be taken not to apply too heavy a coating:
application rate of the diluted emulsion shall be 0.03 to 0.10 gallons per square yard.

B. Cessation temperature for continued compaction of the mat shall be 175° F.
C. Compaction equipment, whether vibratory or non-vibratory, must be of a type and
size approved by the Engineer. Such equipment must be maintained in proper
operating condition and must be ready, at the job site, prior to delivery of
bituminous concrete.
D. On certain bridge deck overlays and paving jobs where, due to physical limitations,
a full roller contingent is not practical, utilize a lesser number of rollers, provided all
compaction requirements are met.
E. Non-vibratory Rollers:
1. In general, rolling shall consist of initial or breakdown rolling, intermediate
rolling and final or finish rolling. Rolling shall be performed with at least
two power-driven steel-wheel tandem or 3-wheel roller weighing not less
than 10 tons.
2. Intermediate rolling may be done with a self-propelled pneumatic tire roller.
If a pneumatic tire roller is used, it shall be equipped with wide-tread
compaction tires capable of exerting an average contact pressure from 60 to
90 pounds per square inch uniformly over the surface, adjusting ballast and
tire inflation pressure as required. Furnish evidence regarding tire size,
pressure and loading to confirm that the proper contact pressure is being
developed and that the loading and contact pressure are uniform for all
wheels.
3. All non-vibratory rollers shall travel at a speed no greater than 5 mph (440
fpm).
F. Vibratory Rollers:
1. A vibratory roller may be included in the compaction train providing the
vibratory roller is operated in accordance with the manufacturer's
recommendations. The vibratory roller shall be of a self-propelled type
specifically designed for the compaction of bituminous concrete.
02511/5-7
2. Vibratory rollers shall be equipped with a speed control device which shall
be set to prevent the roller from traveling in excess of 2-1/2 mph or 220 fpm
when the roller is operating in a vibratory mode, and 5 mph or 440 fpm
when the roller is operating in a static mode.
3. Vibratory rollers shall be shut off from the vibrating mode when reversing
directions. Vibratory rollers shall be equipped with automatic reversing
eccentrics (weights).
4. One vibratory roller may be substituted for both a breakdown roller and
pneumatic roller for the compacting train. The course shall be finish-rolled
with a steel-wheel tandem roller having a minimum weight of 10 tons.
5. Dual vibrating drum roller meeting the requirements of a steel-wheel tandem
roller and operating in the static mode may be used as the finish roller,
however, this single vibratory shall not be used as both the breakdown roller
and the finish roller.
6. One vibratory roller and one steel-wheel tandem roller shall be provided for
each single-lane paver. The type(s) of rollers and number must be approved
by the Engineer.
7. THE USE OF A VIBRATORY ROLLER IN THE DYNAMIC OR
VIBRATORY MODE IS STRICTLY PROHIBITED ON BRIDGE
DECKS OR CONCRETE STRUCTURES.
8. The Contractor assumes full responsibility for the cost of repairing all
damages which may occur to highway components and adjacent property. If
the Engineer determines that the compaction obtained is less than that
specified, or damage to highway components and/or adjacent property
occurs with the use of the vibratory compaction equipment, the Contractor at
no additional expense, shall immediately cease using the equipment and
shall proceed with the work in accordance with the conventional compaction
procedure outlined in the specifications.
3.06 SURFACE TEST OF THE PAVEMENT
A. Random spot-checks shall be performed with a contractor supplied, standard ten
foot straightedge. Provide or designate some employee whose duty it is to use the
straightedge under the observation of the Engineer.
02511/6-7
B. Finished pavement shall not vary more than 1/4 inch from a 10 foot straightedge
applied parallel to the centerline of the pavement. Any irregularity of the surface
exceeding the above limits shall be corrected. Depressions which may develop after
the initial rolling shall be remedied. Such compression or compositions, or that do
not comply with the requirements of the specifications shall be taken up, removed
and replaced with suitable mixture, properly laid in accordance with these
specifications at the expense of the Contractor.
C. The surface of the finished base course shall not vary by more than 3/8 inch from a
10 foot straightedge applied perpendicular to the centerline of the pavement.
3.07 JOINTS
A. Placement of the bituminous material shall be as continuous as possible. Rollers
shall not pass over the unprotected end of a freshly-placed mixture.
B. Transverse joints shall be formed by cutting back on the previous run, existing
bituminous concrete pavement, or bituminous concrete driveways to expose the full
depth of the course. Waste materials shall be disposed of in an acceptable manner.
C. On cold joints, a brush coat of asphaltic material or approved equal shall be used on
contact surfaces of transverse and longitudinal joints just before additional mixture
is placed against the previously rolled material.
D. The longitudinal joint in one layer shall offset the previous joint in the layer
immediately below by approximately six inches. However, the joint in the top
layer shall be at the centerline of the roadway.
E. In compacting the joint, the steel-wheel roller shall be shifted onto the previously
placed lane so that only 1 or 2 inches of the drive wheel extends over the
uncompacted material. The steel wheel roller shall continue to roll along this line
and its position shifted gradually across the joint until the joint has been rolled with
the entire width of the drive wheel. Rolling with steel wheel and pneumatic-tired
rollers shall be continued until a thoroughly compacted, neat joint is obtained.
F. When the vibratory roller is used for breakdown rolling, compacting the joint shall
be accomplished with the roller on the uncompacted material shifted 1 to 2 inches
across the joint onto the previously placed lane.
