C.

Electronic system equipment shall be protected by dealing with each group of related devices as a "cluster" of equipment and protecting all metallic circuits which enter and leave the cluster. The cluster may be as large as a computer room, control room or equipment room or as small as an individual equipment cabinet. For purposes of establishing maximum size, all equipment within a protected cluster shall fall within a circular area of not greater than twenty-five feet in radius around a common point. All metallic circuits entering and leaving the equipment cluster shall be grouped together at a common point or "window" not larger than four by eight feet in dimension and protected with one exception. Circuitry which is supported by equipment within the cluster and extending beyond the cluster to serve devices within the building shall not require protection provided all of the following conditions are met: 1.

Circuitry is enclosed within ferrous metal conduit.

2.

No wiring within the raceways containing such circuits extends beyond the confines of the building.

3.

No connection is made between this wiring and conduit ground outside of the protected perimeter established for the equipment cluster.

4.

All devices connecting to such circuits shall have no connections to conduit, other grounds or other power sources outside the perimeter established for

All system wiring shall be classified into protected and non-protected categories.

SURGE SUPPRESSION BONDING AND GROUNDING 60060986 - March 24, 2010

267090-8

Wiring on the exposed side of suppression devices shall be considered unprotected. Surge suppressor grounding and bonding conductors shall also fall into this category.

2.

B.

All wiring between surge suppressors and protected equipment shall be considered protected. Isolated circuitry exempted from surge suppression requirements in part one of this section shall also be considered protected.

C.

A minimum of three inches of separation shall be provided between parallel runs of protected and unprotected wiring in control panels, terminal cabinets, terminal boards and other locations. In no case shall protected and unprotected wiring be bundled together or routed through the same conduit. Where bundles of protected and unprotected wiring cross, such crossings shall be made at right angles.

INSTALLATION OF SUPPRESSORS A.

Suppressors shall be installed as close as practical to the equipment to be protected consistent with available space. Where space permits and no code restrictions apply, suppressors may be installed within the same cabinet as the protected equipment. Suppressors installed in this manner shall utilize the equipment chassis as a medium for bonding of their ground terminals. Bonding jumpers not exceeding two inches in length shall be installed between the chassis and suppressor ground terminals. Bolted connections with star washers shall be used to insure electrical and mechanical integrity of connections to the equipment chassis.

B.

Suppressors shall be installed in a neat, workmanlike manner. Lead dress shall be consistent with recommended industry practices for the system on which these devices are installed.

C.

Bonding between ground terminals for power and signal line suppressors serving a particular item or cluster of equipment shall be kept as short as possible. Where practical, suppressors shall be installed in a common location for the cluster with their ground terminals bonded closely together. For installations requiring separation between the various suppressor grounds and equipment chassis within an equipment cluster, the following table shall be used to determine bonding conductor requirements (distances are measured between most distant suppressor or chassis grounds): BONDING DISTANCE MATERIAL ------------------------------------------0 - 10 feet #6 AWG Bare Copper (Solid) 10- 25 feet 1-1/2" Copper Strip 26ga. Min. 25- 50 feet 3" Copper Strip 26ga. Min. Over 50 feet 6" Copper Strip 26ga. Min. Care shall be exercised to avoid connection of incidental grounds to the bonding bus system.

D.

Where terminal cabinets are used to house surge suppressors, painted steel backboards shall be used to serve as a low impedance ground plane for bonding surge suppressor leads together. Terminal boards used for the same purpose shall be laminated with a single sheet of 14 ga. galvanized steel to serve as a ground plane for suppressors. Suppressors with ground

SURGE SUPPRESSION BONDING AND GROUNDING 60060986 - March 24, 2010

267090-9

terminals not inherently bonded to the ground plane through their mounting shall be bonded to this plane using a two-inch maximum length of #12AWG copper wire and suitable lug. Ground planes and backboards shall be drilled to accept self tapping screws, any paint in the area of the bond shall be removed and star washers shall be used. E.

PART 2 PRODUCTS 2.1 PUMPING SYSTEM CONTROLLER OPERATION A.

The pump control panel (PCP) system shall perform all logic operations necessary to sequence and alternate the pumps to accomplish proportional level control and to ensure equal run times on all pumps. The pump controller shall also automatically select one or multiple backup units in the event of a single or multiple pump failure. The pump controller shall interface with the VFD's through an analog module interface. The pump controller coordinates the operation of the pump drive system; monitors status of the complete plant operation and provides the telemetry interface. In normal operation the controller shall schedule the pumps on and off to maintain wetwell level. The level control parameters will be based on values set by the operator from the PCP graphic screen. The initial wetwell proportional values are as indicated on the drawings. The control levels set by the operator are to be checked by the PCP to be within the minimum and maximum limits established. Minimum low level limits will be 3.4 feet above wetwell floor to protect pumps from running dry which is also the low alarm point. Maximum high level control limit will be 10.4 feet above wetwell floor which is also the high level float. The high high level float is initially set for 11.4 feet above the wetwell bottom and will activate the backup pump controller. Also provide virtual high level alarms from the level transmitter signal at 3” below the “start diesel pump1 start” level and 3” below the “start diesel pump2 start” level.

B.

The following operating modes shall be required for the pump controller: 1.

Maintain the wetwell level established by the proportional level control system, automatically and without regard to system flow within a 0.2 feet level deviation. The turn on and turn off level values for each pump (lead, lag and lag-2 and lag-3) will be operator configurable with the initial values as indicated on the drawings. The pump controller shall insure speed matching of all pumps. 2. Allow or disallow automatic operation of each pump via telemetry or locally from the operator interface. 3.

Provide for sensing of VFD current.

4. Provide for pump shutdown on fault indication from pump control and status module (Fairbanks Morse SubGard). INSTRUMENTATION AND CONTROL SYSTEM 60060986 - March 24, 2010

268500-3

C.

For each Drive in the system, the controller program shall control the RUN command and specify the operating mode (LEAD, LAG, LAG-2, LAG-3) of the Drives. The software internal to the controller shall coordinate the Drives to allow a lower priority pump to move up in the priority string in the event of the next higher pump drive has faulted.

D.

As the level in the wetwell increases and the lead pump is running at full speed, the level reaches the “start lag pump” setpoint, a signal shall activate and latch to call on the lag pump. The lag pump will come on line and quickly ramp up and match the speed of the lead pump. The pumps will operate as a speed matched pair. As the level continues to rise and the Lead and Lag pumps are running at full speed, the level reaches the “start lag-2 pump” level, a signal shall activate and latch to call on the Lag-2 pump. Same for the Lag-3 pump.

E.

As demand increases and decreases, the Pump controller shall stage on and off the lag and lag-2 &3 pumps based on “lag pump stop” elevation, lag-2 & lag-3 pump stop elevation. As flow decreased further the lead pump ramps down based on level to minimum speed. The minimum speed is maintained until the level drops further to a “stop lead pump” wetwell level setpoint. The lead VFD pump shall be alternated on each operation based on the pump with the least hours. The PCP monitors the flow rate of the pump station through the magnetic flowmeter, and totalizes the pulsed volume. If the flow rate drops below a setpoint initially set for 50gpm after a time delay (initial setting of 30sec) with the pump running, an alarm is initiated and the lead pump is shutdown. The VFD minimum speed programmed into the VFD shall be set to maintain a flowrate with an initial setpoint of 50gpm for all head conditions.

F.

The pump controller shall monitor the signals of two (2) redundant level transmitters using either as a backup or check of the other. Each transmitter shall be totally independent of each other with independent power supplies. The pump controller will generate an alarm if the transmitter signals are more than a predetermined (operator) configurable percent deviation from each other. The operator shall be able to select either level or an average of both level transmitters to control from. The selection shall be locally at the pump controller. Normally the average of the level transmitters shall be used for control. In the event the levels are more than 10% apart the higher of the two shall be used for control and an alarm shall be indicated to the operator. Signals less than 4ma or greater than 20ma shall be ignored and the other used for control. A backup pump controller shall override the control to the VFDs on initiation of a high-high level switch operation. The VFDs shall be programmed to start and run at a predetermined speed until a second low level float activates.

G.

The control signals to and from the PCP controller shall be as shown in the I/O PCP appendix.

2.2 PUMP CONTROLLER ENCLOSURE A. The pump system controller shall be housed in a free standing NEMA type 12 enclosure of approximately 36" wide, 24” depth and 72” height.

MATERIALS

CRUSHED CONCRETE A.

Composition- Base material shall conform to the following gradation: SIEVE SIZE 2" 1 1/2" 3/4" 3/8" No. 4 No. 10 No. 50 No. 200

PERCENT BY WEIGHT PASSING 100 98 - 100 65 - 90 45 - 75 35 - 60 25 - 45 5 - 25 0 - 10

Material for Crushed Concrete Base shall consist only of crushed concrete and such additive materials as may be approved by the Engineer for the purpose of facilitating construction and achieving the desired characteristics of the finished in-place product. Material which shows a significant tendency toward adverse chemical or CRUSHED CONCRETE BASE COURSE 60060986 - March 24, 2010

321129-1

physical change on exposure to moisture will not be acceptable. The material shall be free of any Ferrous Metals. B.

Mechanical and Physical Properties- The material shall not contain lumps, balls, or pockets of sand or clay material in size or quantity sufficient to be detrimental to the proper bonding, finishing, or strength of the crushed concrete base. The specific mechanical and physical properties of crushed concrete aggregate and any additive materials permitted in the construction of Crushed Concrete Base under this contract shall be determined on the basis of test results as the work progresses. C. The Crushed Concrete material used in construction of crushed concrete base shall have an LBR value of not less than 100PART 3 - EXECUTION OF WORK

3.01

TRANSPORTING CRUSHED CONCRETE The material shall be transported to the point where it is to be used, over crushed concrete previously placed where possible, and dumped at the end of the preceding spread. Hauling over the subgrade, or dumping on the subgrade for further placement operations, will be permitted only when, in the opinion of the Engineer, such procedures will not adversely affect the integrity of the completed base and subgrade.

3.02

EQUIPMENT A.

Crushed Concrete Base - The rock shall be accomplished by mechanical spreader, equipped with a device which strikes off the rock uniformly to laying thickness, and capable of producing an even distribution of crushed concrete aggregate. For crossovers, intersections and ramp areas; for roadway widths of 20 feet or less; for the main roadway area when forms are used and for any other areas where the use of a mechanical spreader is not practicable; spreading may be done by bulldozers or blade graders.

B.

Pressure Distributor - The pressure distributor shall be equipped with pneumatic tires having a sufficient width of rubber in contact with the road surface to avoid breaking the bond or forming a rut in the surface. The distance between the centers of openings of the outside nozzles of the spray bar shall be equal to the width of the application required, within an allowable variation two (2) inches. The outside nozzle at each end of the spray bar shall have an area of opening not less than 25 percent nor more than 75 percent, in excess of the other nozzles. All other nozzles shall have uniform openings. When the application covers less than the full width, the normal opening of the end nozzle at the junction line may remain the same as those of the interior nozzles. less than the full width, the normal opening of the end nozzle at the junction line may remain the same as those of the interior nozzles.

3.03

SPREADING CRUSHED CONCRETE A.

Method of Spreading - The crushed concrete shall be spread uniformly with equipment as specified in 3.02 A. above. All segregated areas of fine or coarse rock shall be removed and replaced with properly graded rock.

CRUSHED CONCRETE BASE COURSE 60060986 - March 24, 2010

321129-2

B.

3.04

Number of Courses - When the specified compacted thickness of the base is greater than six inches, the base; shall be constructed in two courses. The thickness of the first course shall be approximately one-half the total thickness of the finished base, or enough additional to bear the weight of the construction equipment without disturbing the subgrade.

COMPACTING AND FINISHING BASE A.

Single-Course Base - For single-course base, after the spreading is completed the entire surface shall be scarified and then shaped so as to produce the required grade and cross section after compaction.

B.

Double-Course Base - For double-course base, the first course shall be cleaned of foreign material and bladed and brought to a surface cross section approximately parallel to that of the finished base. Prior to the spreading of any material for the upper course, the density tests for the lower course shall be made and the Engineer shall have determined that the required compaction has been obtained. After the spreading of the material for the final course is completed, its surface shall be finished and shaped so as to produce the required grade and cross section after compaction, and free of scabs and laminations.

C. Moisture Content - When the material does not have the proper moisture content to insure the required density, wetting or drying will be required. When water is added it shall be uniformly mixed-in by disking to the full depth of the course which is being compacted. Wetting or drying operations shall involve manipulation, as a unit, of the entire width and depth of the course which is being compacted. D. Density Requirements - After spreading is completed the crushed concrete shall be uniformly compacted, with water being added as required, to a density of not less than ninety eight percent (98%) of the maximum density as determined by AASHTO T-180. during final compaction operations, if the blading of any areas is necessary to obtain the true grade and cross section, the compacting operations for such areas shall be completed prior to the performance of density tests on the finished base. Crushed concrete base for shoulder pavement shall be compacted to a density not less than ninety eight percent (98%) of the maximum density as determined under AASHTO T 180. E.

Density Test - At least three density determinations shall be made on each day's final compaction operations on each course, and the density determinations shall be made at more frequent intervals if deemed necessary by the Engineer. During final compacting operations, if blading of any areas is necessary to obtain the true grade and cross section, the compacting operations for such areas shall be completed prior to making the density tests on the finished base.

F.

Correction of Defects 1. Contamination of Base Material - If, at any time, the subgrade material should become mixed with the base course material, the Contractor shall, without additional compensation, dig out and remove the mixture, reshape and compact

CRUSHED CONCRETE BASE COURSE 60060986 - March 24, 2010

321129-3

the subgrade and replace the materials removed with clean base material, which shall be shaped and compacted as specified above. 2. Cracks and Checks - If cracks or checks appear in the base, either before or after priming, which, in the opinion of the Engineer, would impair the structural efficiency of the base, the Contractor shall remove the cracks or checks by rescarifying, reshaping, adding base material where necessary, and recompacting. G. Compaction and Finishing Base - Dynamic Compactor with vibratory rollers shall not be used on this project and shall not be permitted at the job site. The contractor is responsible for all damages caused by compaction operations.

3.05

QUALITY CONTROL A.

Testing Surface - The finished surface of the base course shall be checked with a templet cut to the required grade and with a 15-foot straightedge laid parallel to the centerline of the road. All irregularities greater than 1/4 inch shall be corrected by scarifying and removing or adding rock as required, after which the entire area shall be recompacted as specified hereinbefore. In the testing of the surface, the measurements will not be taken in small holes caused by individual pieces of rock having been pulled out by the grader.

B.

Thickness Requirements: 1. Measurements - Thickness of base shall be measured at intervals of not more than 200 feet. Measurements shall be taken at various points on the cross section, through holes not less than three inches in diameter. 2. Areas Requiring Correction - Where the compacted base is deficient by more than 1/2 inch from the thickness called for in the plans, the Contractor shall correct such areas by scarifying and adding rock. The base shall be scarified and rock added for a distance of 100 feet in each direction from the edge of the deficient area. The affected areas shall then be brought to the required state of compaction and to the required thickness and cross section. 3. Deficient Areas Left in Place - As an exception to the requirement for correcting areas of base which show a thickness deficiency exceeding the allowable 1/2 inch, if so approved in writing by the Engineer. Any of such areas in which the extent of the deficiency might be considered as not sufficient to seriously impair the required strength of the base may be left in place. No payment, however, will be made for such deficient areas left in place and not corrected. 4. Density Testing - After the base is completed, the density shall be checked at intervals of not more than 300 feet of roadway or 2,400 sq. ft. of area paving. If any field density tests are below the specified density, rework and recompact the area until the minimum density is achieved. MAKE AT LEAST THREE DENSITY DETERMINATIONS ON EACH DAY'S FINAL COMPACTION OPERATIONS ON EACH COURSE. The density determinations shall be made at more frequent intervals if deemed necessary by

CRUSHED CONCRETE BASE COURSE 60060986 - March 24, 2010

Cleaning Base and Protection of Adjacent Work 1.

Before any bituminous material is applied, all loose material, dust, dirt, caked clay and other foreign materials which might prevent proper bond with the existing surface shall be removed for the full width of the application. Particular care shall be taken in cleaning the outer edges of the strip to be treated, to insure that the prime or tack coat will adhere.

2.

When the prime or tack coat is applied adjacent to curb and gutter, valley gutter or any other concrete surfaces, such concrete surfaces (except where they are to be covered with a bituminous wearing course) shall be covered with heavy paper, or otherwise protected while the prime or tack coat is being applied. Any bituminous material deposited on such concrete surfaces shall be removed.

Weather Limitations Prime and tack coats shall be applied when the air temperature, in the shade, is above 40°F, and when all other weather conditions and the condition of the surface are suitable.

D.

Application of Prime Coat 1.

General: The surface to be primed shall be clean and the moisture content of the base shall not exceed 90 percent of the optimum moisture. The temperature of the prime material shall be between 100°F and 180°F. The actual temperature shall be that which will insure uniform distribution. The material shall be applied by means of a pressure distributor. The amount to be applied will be dependent on the character of the surface and shall be sufficient to coat the surface thoroughly and uniformly, with no excess. A prime coat is required on newly constructed limerock, shell, and sand clay bases.

4.

Sanding a.

If an emulsified asphalt is used to prime coat, the primed base shall be uniformly covered by an application of sand-bituminous hot mix or screenings at an approximate rate of ten pounds per square yard. The entire surface of the sand-bituminous hot mix or screenings cover material shall be rolled with a traffic roller as required to produce a reasonable dense mat.

b.

If material other than emulsified asphalt is used for prime coat, the primed base shall be covered by a light uniform application of cover material. If considered necessary for proper distribution of spread, the cover material shall be lightly dragged with a drag broom, after which it shall be rolled with a traffic roller, for at least ten passes over the entire area.

Application of Tack Coat 1.

General: Where a bituminous surface is to be laid and a tack coat is required, the tack coat shall be applied as specified herein below.

2.

Use a tack coat on existing pavement to be resurfaced, primed bases in areas which have become excessively dirty and cannot be cleaned, or in areas where the prime has cured and lost its bonding effect.

3.

Method of Application: The tack coat shall be applied with a pressure distributor except that, on small jobs if approved by the Engineer, application may be by other mechanical devices or by hand methods. The bituminous material shall be heated to a suitable temperature and shall be applied in a thin, uniform layer.

Rate of Application: The rate of application shall be between 0.02 and 0.08 gallon per square yard. For tack coat applied on concrete pavement which is to be surfaced, the rate of application may exceed the upper limit.

5.

Curing and Time of Application: The tack coat shall be applied sufficiently in advance of the laying of the bituminous mix to permit drying but shall not be applied so far in advance that it might lose its adhesiveness as a result of being covered with dust or other foreign material.

6.

Protection: The tack coat surface shall be kept free from traffic until the subsequent layer of bituminous hot mix has been laid. END OF SECTION

Asphalt Base Course Asphalt base courses shall met the requirements of paragraphs 2A and 2B.

PART 3 - EXECUTION A.

Hot Bituminous Mixtures 1.

Plant operations shall not begin unless all weather conditions are suitable for the laying operations.

2.

The mixture shall be spread only when the surface upon which it is to be laid has been previously prepared, is intact, firm and properly cured, and is dry. No mixture shall be spread that cannot be finished and compacted during daylight hours. The mixture shall be spread only when the air temperature (the temperature in the shade away from artificial heat) is above 40°F for layers greater than one inch (100 lbs per square yard) in thickness and 45°F and above for layers one inch (100 lbs per square yard) or less in thickness (this includes leveling courses). No mixture shall be placed when there is evidence of a frozen base. The mixture shall not be spread when the wind is blowing to such an extent that proper and adequate compaction cannot be maintained or when sand, dust, etc., are being deposited on the surface being paved, to the extent that the bond between layers will be diminished.

3.

Mixing at the asphalt plant shall be sufficient to produce a thoroughly and uniformly coated mixture. The ingredients of the mix shall be heated and combined in such a manner as to produce a mixture, which shall be at a temperature, when discharged from the pugmill or surge bin, within the range of 230°F to 310°F and within the tolerance shown in the following table:

Temperature Tolerance From Job Mix Formula _________________________________________________________ Any Single Measurement . . . . . . . . . . . . . Average of Any Five Consecutive Measurements . .

+25°F +15°F

_________________________________________________________

ASPHALT PAVEMENT 60060986 - March 24, 2010

321215-7

However, the temperature of the mixture, in all cases, shall be such that will yield an asphalt Kinematic viscosity within the range of 280 and 150 centistokes. The mix temperature will be taken at the plant on the first five loads each day and on an average of once every five loads thereafter. Take corrective action if the temperature fails to fall within the specified tolerance. 4.

The maximum time that any mix may be kept in a hot storage or surge bin is 72 hours. Produce a homogeneous mixture, free from moisture and with no segregated materials, that meets all requirements of the specifications for the mixture, including compliance with the design limits. These requirements shall apply also to all mixes produced by the drum mixer process and all mixes processed through a hot storage or surge bin, both before and after storage.

5.

The mixture shall be transported in tight vehicles previously cleaned of all foreign material and each load shall be covered. The inside surface of the truck bodies shall be thinly coated with soapy water or an emulsion containing not over 5% of oil. Kerosene, gasoline or similar products shall not be used. After the truck bodies are coated and before any mixture is placed therein, they shall be raised so that all excess liquids will be drained out.

6.

Prior to the laying of the mixture, the surface of the base or pavements to be covered shall be cleaned of all loose and deleterious material by the use of power brooms or blowers, supplemented by hand brooming where necessary.

7.

All asphaltic concrete mixtures (including leveling courses), other than adjacent to curb and gutter or other true edges, shall be laid by the string-line method, to assure the obtaining of an accurate, uniform alignment of the pavement edge. The temperature of the mix at the time of spreading shall be within +25°F of the actual mix temperature. The minimum frequency for taking mix temperatures on the road will be an average of one per five trucks. Take corrective action if the temperature range fails to fall within the specified tolerance range. Any mixture caught in transit by a sudden rain may be laid at risk. Should such mixture prove unsatisfactory, it shall be removed and replaced with satisfactory mixture at no additional expense to the Owner. In no case shall the mixture be laid while rain is falling or when there is water on the surface to be covered. The forward speed of the spreader shall be as established by the manufacturer of the equipment and sufficient for an even application. For each paving machine being operated, a separate crew will be required; each crew operating as a full unit. The depth of each layer shall be checked at frequent intervals of approximately 25 feet. Any deviation below the design thickness as shown on the drawings shall be immediately corrected. In limited areas where the use of the spreader is impossible or impracticable, the mixture may be spread and finished by hand. Straight-edging and back-patching shall be done after initial compaction has been obtained and while the material is still hot.

8.

For courses other than leveling, upon arrival, the mixture shall be dumped into a mechanical spreader and immediately spread and struck-off to the full width required and to such loose depth for each course that, when the work is completed, the required weight of mixture per square yard, or the specified thickness, will be secured. An excess amount of mixture shall be carried ahead of the screed at all times. Hand raking shall be done behind the machine as required. If necessary due to the traffic requirements, the mixture shall be laid in trips in such manner as to

ASPHALT PAVEMENT 60060986 - March 24, 2010

321215-8

provide for the passage of traffic. Where the road is closed to traffic, the mixture may be laid to the full width, by machines traveling in echelon. Before any rolling is started the surface shall be checked, any irregularities adjusted, and all drippings, fat sandy accumulations from the screed, and fat spots from any source shall be removed and replaced with satisfactory material. No skin patching shall be done. When a depression is to be corrected while the mixture is hot, the surface shall be well scarified before the addition of fresh mixture. 9.

For leveling courses, all depressions in the existing surface more than one inch deep shall be filled by spot patching with leveling course mixture and then thoroughly compacted prior to spreading any leveling course. All leveling courses shall be placed by the use of two motor graders (one of which is equipped with a spreader box) unless otherwise shown in the plans. When the total asphalt mix provided for leveling exceeds 50 pounds per square yard, the mix shall be placed in two or more layers, with the average spread of any layer not to exceed 50 pounds per square yard. When Type S-III Asphaltic Concrete is used for leveling, the average spread of a layer shall not be less than 50 lbs per square yard nor more than 75 pounds per square yard. The quantity of mix for leveling shown in the plans represents the average for the entire project; however, the rate of application may vary throughout the project. When leveling in connection with base widening, all the leveling mix must be placed prior to the widening operation. When a leveling course is specified to be placed over cracked concrete pavement (including existing concrete pavement covered with an asphaltic surface), the first layer of leveling shall be placed as soon as possible but no later than 48 hours after cracking the concrete. The remainder of the leveling course shall be placed in the normal sequence of operations. Where a leveling course is to be placed over existing concrete pavement or bridge decks, the excess joint filler in the cracks and joints shall be trimmed flush with the surface prior to placing the first layer of the leveling course.

10.

For each paving or leveling train in operation, furnish a separate set of rollers, with their operators. The following equipment, sequence and coverage are only suggested for use based on past successful performance. Utilizing whatever equipment selected, the sequence and coverage of rolling shall meet the minimum density requirements specified:

11.

a.

Seal rolling by using tandem steel rollers weighing 5 to 12 tons, following as close behind the spreaders as is possible without pick-up, undue displacement or blistering of the material.

b.

Rolling with self-propelled pneumatic-tired rollers, following as close behind the seal rolling as the mix will permit. The roller shall cover every portion of the surface with at least five passes.

c.

Final rolling with the 8- to 12-ton tandem steel rollers, to be done after the seal rolling and pneumatic-tired rolling have been completed, but before the internal pavement temperature has dropped below 175°F.

The initial rolling shall be longitudinal. Where the lane being placed is adjacent to a previously placed lane, the center joint shall be pinched or rolled, prior to the rolling of the rest of the lane. After the rolling or pinching of the center joint, the rolling shall continue across the mat by overlapping each previous roller path by at least one-half the width of the roller wheel. The motion of the roller shall be slow enough to avoid displacement of the mixture, and any displacement shall be corrected at once by the use of rakes, and the addition of fresh mixture if required. Final rolling shall be

ASPHALT PAVEMENT 60060986 - March 24, 2010

321215-9

continued until all roller marks are eliminated. Rolling with the self-propelled, pneumatic-tired rollers shall proceed at a speed of 6 to 10 miles per hour, and the area covered by each roller shall not be more than 4,000 square yards per hour, except that for Type S Asphaltic Concrete, this maximum rate of coverage shall be 3,000 square yards per hour. a.

A sufficient number of self-propelled pneumatic-tired rollers shall be used such that the rolling of the surface for the required number of passes will not delay any other phase of the laying operation nor result in excessive cooling of the mixture before the rolling is complete. In the event that the rolling falls behind, the laying operation shall be discontinued until the rolling operations are sufficiently caught up.

b.

Areas which are inaccessible to a roller (such as areas adjacent to curbs, headers, gutters, bridges, manholes, etc.) shall be compacted by the use of hand tamps or other satisfactory means.

c.

Self-propelled pneumatic-tired rollers shall be used for the rolling of all patching and leveling courses. Where the initial leveling course is placed over broken concrete pavement, the pneumatic-tired roller shall weigh at least 15 tons. For Type S-III Asphaltic Concrete leveling courses, the use of a steelwheel roller, to supplement the traffic rollers, will be required. On other leveling courses, the use of a steel-wheeled roller will be required on all passes after the first.

d.

The rollers shall not be allowed to deposit gasoline, oil or grease onto the pavement, and any areas damaged by such deposits shall be removed and replaced. While rolling is in progress, the surface shall be tested continuously and all discrepancies corrected to comply with the surface requirements. All drippings, fat or lean areas and defective construction of any description shall be removed and replaced. Depressions which develop before the completion of the rolling shall be remedied by loosening the mixture and adding new mixture to bring the depressions to a true surface. Should any depression remain after the final compaction has been obtained, the full depth of the mixture shall be removed and replaced with sufficient new mixture to form a true and even surface. All high spots, high joints and honeycomb shall be corrected. Any mixture remaining unbonded after rolling shall be removed and replaced. Any mixture which becomes loose or broken, mixed or coated with dirt or in any way defective, prior to laying the wearing course shall be removed and replaced with fresh mixture which shall be immediately be compacted to conform with the surrounding area. Areas of defective surface may be repaired by the use of indirect heat. No method of repair involving open-flame heaters shall be used.

12.

Shoulder pavements wider than 5-1/2 feet shall be compacted by the use of equipment of the type required for other asphaltic concrete pavements. Compaction of asphaltic concrete 5-1/2 feet or less in width, shall be done by the use of tandem steel rollers not exceeding 12 tons in weight. Other compaction in such restricted widths shall be by the use of rubber-tired equipment.

14.

The density of a completed course shall be at least 94% of the laboratory density.

15.

Placing of the mixture shall be as continuous as possible and the roller shall not pass over the unprotected end of the freshly laid mixture except when the laying operation

ASPHALT PAVEMENT 60060986 - March 24, 2010

321215-10

is to be discontinued long enough to permit the mixture to become chilled. When the laying operation is thus interrupted, a transverse joint shall be constructed by cutting back on the previous run to expose the full depth of the mat. 16.

Where only a portion of the width of pavement is to be laid and opened to traffic, longitudinal joints shall be formed by rolling the exposed edge of the strip first laid. When the adjacent strip is constructed, the Engineer may require the edge of the mixture in place to be trimmed back to expose an unsealed or granular vertical surface. Where the strip first laid is closed to traffic, the edge shall not be sealed but shall be left vertical and the adjacent strip placed against it without trimming.

17.

When fresh mixture is laid against the exposed edges of joints (trimmed or formed as provided above), it shall be placed in close contact with the exposed edge so that an even, well-compacted joint will be produced after rolling.

18.

The finished surface shall be of uniform texture and compaction and shall be smooth. The surface shall have no pulled, torn, or loosened portions and shall be free of segregation, sand streaks, sand spots, or ripples. Any area of the surface which does not meet the foregoing requirements shall be corrected.

19.

All pavements (both intermediate and final courses), intersections, acceleration lanes, deceleration lanes, tapers, crossovers, transitions at beginning and end of project, and similar areas shall be tested with a straightedge for surface tolerance. Any individual surface irregularity in these areas in excess of 3/16-inch as determined by a 15-foot straightedge shall be corrected and retested. Provide a 15foot manual straightedge at the job site at all times during the paving operation for checking joints and surface irregularities.

20.

If the Owner elects to waive corrections, the appropriate pay quantity for Asphaltic Concrete shall be reduced by the equivalent quantity of materials which would have been removed and replaced if the correction had been made.

21.

a.

Where the pay quantity is in square yards, the reduction is based on the area which would have been removed multiplied by the ratio of the layer thickness to the total thickness of the type of mix specified.

b.

Where the pay quantity is in tons, the reduction is based on the volume which would have been removed (length x lane width x layer thickness) multiplied by the laboratory density for the mix.

c.

Where the project is a lump sum pay quantity based on amount completed, the appropriate reduction in percent complete shall be calculated based on the total amount of paving.

Select one of the following correction methods unless overlaying is prohibited. a.

Removing and Replacing: If correction is made by removing and replacing the pavement, the removal must be for the full depth of the course and extend at least 50 feet on either side of the defective area, for the full width of the paving lane.

b.

Overlaying: If correction is made by overlaying, the overlaying shall cover the length of the defective area and taper uniformly to a featheredge thickness at a minimum distance of 50 feet on either side of the defective area. The overlay

B.

C.

D.

Construction Methods - General 1.

Provide and establish grass in all areas designated on the drawings and that are disturbed during construction (except areas to be paved, landscaped or covered with structures).

2.

Do not fertilize when wind velocities exceed 15 miles per hour. Sod only when the soil is in proper condition to induce growth.

3.

When a length of roadway slopes or adjacent areas have been graded and made ready, commence grassing in accordance with these specifications. Incorporate grass covering into the project at the earliest practical time in the life of the contract to reduce potential erosion.

4.

Store fertilizer in dry locations away from contaminants. Sprinkle sod with water and protect from exposure to wind and direct sunlight until planted. Provide covering that will allow air to circulate so that heating will not develop.

Preparation of Area to be Grassed 1.

Prepare the areas to be grassed by disc-harrowing and thoroughly pulverizing them to a depth of at least 6 inches.

2.

Bring all areas to be grassed to finished grades, remove weeds, surplus dirt and rock debris over 1 inch in diameter, and rough grade the area.

3.

Test the soil for pH. If the soil is below a pH level of 5.5, spread lime to raise the pH level to at least 5.5.

4.

Uniformly apply fertilizer at the rate of 400 to 500 pounds per acre. Immediately after the fertilizer and/or lime is spread over the area, mix them into the soil to a depth of approximately 4 inches.

5.

Float the area to a smooth uniform grade. Slope all areas to drain. Establish flow lines as shown on the drawings. Finish areas to be grassed approximately 1 inch below top of adjoining curb or pathway.

Sodding 1.

Incorporate sodding into the project at the earliest practical time in the life of the contract. Do not use sod which has been cut for more than 3 days. Stack any sod which is not planted within 24 hours after cutting and maintain properly moistened.

G.

2.

Place the sod on a prepared surface, with abutting joints. Fill any gaps or cracks between sod blocks with sod. Roll with a minimum one-ton roller to obtain an even surface. Bring the sod edge in a neat, clean manner to the edge of all paving and shrub areas and project limits.

3.

Where sodding is used in drainage ditches, stagger the setting of the pieces to avoid a continuous seam along the line of flow.

4.

On areas where the sod may slide due to height and slope, peg the sod with pegs driven through the sod blocks into firm earth at suitable intervals. Replace any pieces of sod which, after placing, show an appearance of extreme dryness.

Mowing 1.

Mow first when the grass reaches a height of 3 to 4 inches. Mow a second time when the grass reaches a height of 6 inches and before a seedhead occurs. Subsequent mowings should establish a uniform grass surface of 2-1/2 inches and be made before seedhead occurs. All mowings should be made with a cut height as low as possible to stop shading of the Bahia grass.

2.

Mow sod to establish a uniform grass surface of 2-1/2 inches.

3.

Provide equipment for mowing that does not rut the soil surface. Fill any ruts that are in excess of two (2) inches deep with native soil free from twigs and rocks larger than 1 inch in diameter. Temporarily suspend mowing operations when the soil is too wet to provide adequate support and traction for equipment.

Watering 1.

Maintain a balanced watering program until the acceptance of work.

2.

Apply water in sufficient quantities and as often as seasonal conditions require to keep the grassed areas moist.

3.

Provide supplemental water and irrigate seed areas when the rainfall is not adequate to maintain soil moisture necessary for germination and growth of the grass. It is Contractor's responsibility to determine the quantities of water required and when to irrigate. This obligation shall remain in full force and effect until final acceptance of the work by Owner and shall be provided at no additional cost to Owner.

4.

Owner, at his discretion, may relieve Contractor of this obligation at such time as Owner is able to provide irrigation. This action, however, does not relieve Contractor of the provisions and guarantees set forth in the Contract Documents.

Maintenance 1.

Maintain all grassed areas for a period of 90 days after the date of substantial completion and guarantee against all defects and faults of material and workmanship.

2.

Maintain grass areas by watering, fertilizing, and mowing to establish an even and uniform grass surface of 2-1/2 inches, as specified above.
