300-2.2.1 General . All excess material generated by the grading operations that is not suitable for backfill shall be excavated and disposed of by the Contractor at a legal disposal site.

The Agency makes no claim on the suitability or moisture content of the existing materials. Any suitable local borrow materials at the site that the Contractor wishes to re-use shall be stockpiled by the Contractor. The location of stockpiles shall be approved by the Engineer prior to placement of materials, and all stockpiles shall be protected by erosion control measures.

All subgrade areas to receive fills or structures shall be inspected by the Geotechnical Engineer. All alluvial and colluvial soils, loose or poorly compacted soils, or existing dry material must be reworked before the placement of base or concrete can proceed. Areas where soils are loose or poorly compacted shall be reworked by excavating, blending and recompacting the loose soils to the specified compaction. The existing loose soils to be reworked shall be removed by the Contractor until a firm unyielding surface is exposed or to a depth determined by the Engineer. Dry materials shall be scarified and moisture conditioned to achieve the specified compaction. With the approval of the Geotechnical Engineer, the Contractor may choose to stabilize poorly-compacted areas with geogrid at his own expense.

If the Contractor wishes to temporarily stockpile material for disposal at a later date in any area other than the project area or construction staging area, the Contractor shall locate a suitable space which is outside the Public Right-of-Way and suitable to the Agency. The location of stockpiles shall be approved by the Engineer prior to placement of materials, and all stockpiles shall be protected by storm water pollution prevention and erosion control measures. The stockpiles shall be removed regularly from the Project site so as not to interfere with access to the Project.

If the excavated material is unsatisfactory as excavated for other uses in the Project, as determined by the Engineer, the Contractor shall remove and dispose of such excavated material off the site. The Contractor shall be responsible for obtaining a suitable legal disposal site for any unsuitable excavated materials in accordance with the appropriate section in the Standard Specifications.

300-2.2.2 Wet Material.

Modify this subsection to read as follows:

300-2.2.2 Wet Material. If required excavated material is unsatisfactory for the specified use on the Project solely because the material has a moisture content of four percent (4%) or more above the optimum moisture content, the Contractor shall process the material to reduce the moisture content to an optimum condition, or remove the material and replace it with suitable material. The material may be processed by blending the wet soil with soils having a lower moisture content and / or spreading the excavated material in a manner that enables the material to dry to optimum moisture content. With the approval of the Geotechnical Engineer, the Contractor may choose to stabilize unstable subgrade areas with geogrid at his own expense.

Any objectionable material, including organic and inorganic debris, shall be removed, and shall not be placed in the fill.

The Contractor shall establish rough grade of the areas to be planted by placing fill material to a minimum of six inches (6”) below the finished grade shown on the Plans. The Contractor shall then complete the grading work to establish finished grade by placing a minimum of six inches (6”) of topsoil that has been stockpiled from the existing site or imported.

Excess soil remaining from excavations on the Project site may only be used for fill material when rocks, lumps, cobbles, clods, base material, or other solid materials such as broken concrete or asphalt from removal operations are suitable for the particular area to be filled as determined by the Engineer. Broken concrete or asphalt pavement materials shall not be allowed within site grading fill areas or roadway fills less than three feet (3’) in height, within three feet (3’) of final grade in any area or within five feet (5’) (vertically) of the existing ground water table. Any concrete or asphalt placement shall be approved by the Resident Engineer. Concrete or asphalt pieces shall be less than six inches (6”) in maximum dimension and surrounded by soil particles when used as compacted fill. No nesting shall occur. If the Contractor wishes to use any of the excess material remaining from the Project excavations for any purpose, the material must be suitable for use as fill or backfill and meet the requirements of Subsection 300-4 (“UNCLASSIFIED FILL.”) of the Standard Specifications and the geotechnical investigation for this Project. The Contractor shall first remove all organic material, construction debris, miscellaneous debris, rubbish, and other objectionable materials contained therein, then obtain tests of the material to the project geotechnical testing laboratory to confirm its suitability.

Geotechnical (soil) testing of all fill materials; subgrade, subbase, and base will be conducted by the Agency and the Geotechnical Engineer. Geotechnical (soil) tests may include relative compaction tests, sand equivalent tests, sieve analysis, R-values, etc. The results shall be presented directly by the laboratory to the Engineer. No base or PCC pavement shall be placed prior to the subgrade or subbase being compacted, tested and approved by the Engineer.

The cost of any initial geotechnical (soil) tests shall be borne by the Agency. Additional geotechnical (soil) tests due to the failure of one (1) or more of the initial tests shall be conducted by the laboratory and any costs borne by the Contractor. The Contractor shall make allowances in his construction procedure to permit testing of the Work in progress by the Engineer, and no additional compensation shall be paid to the Contractor for delays due to testing. 08/12/2025

301-1.7 Payment.

Revise this subsection to read as follows:

301-1.7 Payment. The BID SCHEDULE DOES NOT include a bid item for subgrade preparation. Full compensation for Subgrade Preparation required to perform the construction operations specified or shown on the Plans will be considered as included in the price bid for the related items of work, and no additional compensation will be allowed therefore.

Payment for grading operations in areas designated as “grade only” will be considered as included in the price for excavation or fill.

301-2 UNTREATED BASE.
301-2.1 General.

Add the following to this subsection:

Concrete curb, gutter, cross gutter, spandrel, sidewalk, driveway, and flatwork shall be placed on untreated compacted aggregate base, unless the existing material under the areas being repaired is determined to be firm and unyielding by the Engineer. New Asphalt Concrete Pavement shall also be placed on untreated compacted aggregate base. Untreated compacted aggregate base shall have the following thicknesses under respective concrete surface improvement unless shown otherwise on the Plans or specified:

The Contractor will be allowed to reuse any existing base that is removed if the base material is removed without being contaminated by subgrade soils or other deleterious materials. The re-used base material must be moisture conditioned and compacted as specified. The Contractor shall provide water and compact the surface of any base material that will form the foundation for subsequent improvements, to meet the requirements of the Plans and specifications. The Contractor shall remove and replace any existing aggregate base that becomes contaminated.

301-2.3 Compacting.

Add the following as the first paragraph:

301-2.3 Compacting. It shall be the Contractor’s responsibility to provide adequate equipment and methods to accomplish the Work in accordance with these Specifications. The grading shall be done to the elevations provided in the Plans. Any field conditions that prevent the Contractor from matching design elevations shall be immediately notified to the Engineer. 08/12/2025

156 of 364

146

Revise the third paragraph of this subsection to read as follows:

The relative compaction of each layer of compacted base material shall not be less than ninety-five percent (95%) for curbs, driveways and pavement for a minimum depth of one foot (1.0’) below the grading plane. Compaction under sidewalks and in the excepted areas shall be as specified in Subsection 211-1 (“COMPACTION TESTS.”) with each layer of compacted base material having a minimum compaction of ninety percent (90%).

301-2.4 Measurement and Payment.

Revise this subsection to read as follows:

301-2.4 Measurement and Payment. The quantities of new untreated aggregate base will be calculated using the square footage of the improvements constructed on the base, multiplied by the thickness of the base shown on the plans or specified. If the Engineer directs the Contractor to place additional base, the thickness requested by the Engineer will be used in calculating the pay quantity. If the base thickness is increased by the Contractor for his convenience or to avoid performing additional required subgrade preparation, the additional base will not be included in the pay quantity.

Because the determination of whether untreated aggregate base will be needed in certain areas depends on the condition of the existing materials, it is a rough estimate for bidding purposes.

To confirm the pay quantities, the Contractor shall furnish to the Engineer at the time of delivery of the material to the job site a legible copy of a licensed weigh master’s certificate showing gross, tare, and net weights of each truckload of untreated base. Failure of the Contractor to provide a certificate to the Engineer by the end of the day on which the material represented by such certificate is delivered to the job site may, at the discretion of the Engineer, result in the forfeiture of all payment for such material, including any labor and equipment costs or related costs included in the price for furnishing and placing the untreated base.

Payment for untreated compacted aggregate base will be made by Bid Price per CUBIC YARD as shown in the bid. Such bid price shall include full compensation for clearing and grubbing; earthwork; subgrade preparation; supplying, placing, spreading, compacting, and finishing the untreated base; and all other work required to perform the construction operations specified or shown on the Plans, and no additional compensation will be allowed therefore.

Add the following new subsection:

302-1.1 General. In areas where a slurry seal is to be made on existing paving, all cracks one-eighth inch (1/8”) wide or wider shall be sealed prior to the construction of an asphalt concrete overlay. The Engineer will make the sole determination as to which cracks shall be sealed.

All cracks one-eighth to one and one-half inches (1/8” – 1 ½”) wide shall be sealed with a hot applied rubberized asphalt sealant. All cracks shall be cleaned full depth by blowing operations prior to applying the sealant. The sealant shall be Crafco Polyflex Sealant, Type 2 or 3, or an approved equal. The Sealant shall be applied in accordance with the manufacturer’s instructions.

All cracks one and one-half inches (1 ½”) or wider shall be cleaned full depth, a tack coat applied to the edges and filled with a fine asphalt concrete hot mix.

Care shall be taken to avoid excess sealant being applied to the existing asphalt concrete surface. A squeegee shall be used to spread out excess sealant on small cracks. There shall be a one-half inch (½”) deep cup-shaped groove between the existing asphalt concrete surface and the top crack sealant placed in cracks one-half inch (½”) wide or wider. Excess sealant, as solely determined by the Engineer, shall be removed at the Contractor’s expense. Contractor shall keep traffic off of areas receiving crack seal until it has cured to the point where it will not be removed from cracks by vehicle tires. Cracks shall be sealed a minimum of seven (7) days prior to placement of slurry seal.

302-1.2 Measurement and Payment.

SECTION 403 – MANHOLE ADJUSTMENT AND RECONSTRUCTION

403-1 GENERAL.

Modify this subsection to read as follows:

Utility valve, manhole, and vault frames and covers within an area to be paved or graded will be set by the owners thereof to finished grade. The Contractor shall adjust all storm drain manholes, sewer cleanouts and manholes, water valve sleeves and covers not adjusted by the owner, survey monument covers and other miscellaneous facilities requiring adjustment to the finished grade, unless the adjustment is designated as “By Others”, in accordance with the Contract Documents. Existing manholes shall be ramped with a minimum of ten feet (10’) round with temporary asphalt. Temporary asphalt ramps shall be completely removed prior to asphalt overlay. The area around each manhole must be compacted prior to paving. Contractor shall be responsible to provide all riser rings, grade rings, slip cans and/or sleeves needed for adjustments. The Contractor shall coordinate with the various utility companies to ensure that the utility companies complete their adjustment work prior to the completion of the Work.

The Contractor shall exercise care so that surface materials such as rocks, dirt, and debris do not enter sewer lines, manholes, valve and cleanout sleeves, and other utility facilities. In order to prevent contamination, Contractor shall provide a three-quarter inch (3/4”) thick plywood platform to be placed on the concrete shelf at the bottom of sewer manholes prior to starting adjustment work. The shape of this platform shall conform to the circumference of the inside wall at the shelf elevation. After the manhole had been adjusted, the material accumulated on the plywood shelf along with the plywood shelf shall be removed from the manhole and disposed of in accordance with Subsection 401 (“REMOVAL.”) The Contractor shall remove all debris from the interior of manholes, valve covers, and cleanouts and shall clean all foreign material from the top of the frames and covers. The Contractor shall include all costs in the related items of work, and no additional compensation will be allowed.

Add the following new paragraph to this subsection:

Because VID water facility sleeve and cover adjustments in paved areas must be done as the paving operation proceeds, VID typically has a crew working at the same time the Contractor is performing the paving operations. If VID is not able to perform the work due to an unforeseen circumstance, the Contractor shall adjust those facilities to grade on behalf of VID as the paving 08/12/2025

174
work is being done. Because the quantity of VID covers to be adjusted depends on the availability of VID crews to perform the work, the quantity in the Bid is a rough estimate for bidding purposes only. Stipulated unit prices may be included in the Bid to eliminate for all bidders the risk of including prices for those items of work in the bid and not getting the work.

403-2 MANHOLES IN CONCRETE PAVEMENT.

Modify this subsection to read as follows:

Manholes in asphalt concrete pavement shall be set to finish grade in accordance with provisions of 403-3. In the case of Portland cement concrete pavement, manhole frames shall be set to finish grade before paving. Repaving required as a result of reconstructing or adjusting all manhole and vault frames and covers to grade shall be the responsibility of the Contractor and the cost thereof shall be included in the bid item for pavement.

403-3 MANHOLES IN ASPHALT CONCRETE PAVEMENT.

Add the following paragraphs to this subsection:

The Contractor shall mark out and note locations of all manholes, covers, survey monuments, vaults, and other structures located at the street surface before paving operations commence. As the paving operation proceeds, the Contractor shall mark all manholes and other structures with paint for the owner’s ease in locating them in case of an emergency.

The Contractor shall adjust all storm drain manholes, sewer cleanouts and manholes, water valve sleeves and covers, survey monument covers and other structures requiring adjustment to the finished grade within the areas to be paved or planted in accordance with these Project Specifications and the Standard Specifications. The Contractor shall coordinate the adjustment of the covers with the associated utility owner and make sure the utility covers are uncovered and adjusted to grade immediately after the final paving to maintain access in case of an emergency. Frames and covers may need to be temporarily adjusted to be safe and provide access to the utilities during separate base course and surface course paving operations, but only the final adjustment will be a pay item. Repaving required as a result of reconstruction or adjusting frames and covers to grade shall be the responsibility of the Contractor and the cost thereof shall be included in the bid price paid for the related items of work requiring such adjustment.

Sewer and storm drain manholes belonging to Vista shall be adjusted or reconstructed in accordance with the Vista Sewer System Design Standard Specifications. Manholes are either twenty-four inch (24”) single covers or thirty-six inch (36”) two-piece covers. Some manholes have existing cast-iron adjustment rings. For manholes that are in good condition and have no more than one cast-iron adjustment ring, the Contractor may adjust the manholes to grade using another cast-iron adjustment ring, for a maximum of two cast-iron rings. If the grout around the upper precast concrete riser rings or the frame is defective, the Contractor shall adjust the manhole to grade by removing the cover and frame, salvaging the cast-iron rings, and removing 08/12/2025
C9
185 of 364

175
the precast concrete rings until the grout in the remaining precast concrete rings is in good condition, as determined by the Engineer. Then the Contractor shall adjust the frame and cover to grade using new precast concrete riser rings. If the cover is sitting low in the existing frame or adjustment ring, or the frame or cover is defective, the Contractor shall salvage the existing frame, cover, and rings, supply a new frame and cover, and adjust the new frame and cover to grade using precast concrete riser rings. If any manhole is defective to the extent that it requires fifteen inches or more (15”+) of pre-cast concrete riser rings to adjust the cover to grade, the Contractor shall reconstruct the manhole as described in the Specifications.

The Contractor shall exercise care so that surface materials such as rocks, dirt, and debris do not enter sewer lines, manholes, valve and cleanout sleeves, and other utility structures. In order to prevent contamination, Contractor shall provide a three-quarter inch (3/4”) thick plywood platform to be placed on the concrete shelf at the bottom of sewer manholes prior to cold milling pavement work. The shape of this platform shall conform to the circumference of the inside wall at the shelf elevation. After the manhole had been adjusted, the material accumulated on the plywood shelf along with the plywood shelf shall be removed from the manhole and disposed of in accordance with Section 401 (“REMOVAL.”) The Contractor shall remove all debris from the interior of manholes, valve covers, and cleanouts and shall clean all foreign material from the top of the frames and covers.

Because VID water valve cover cover adjustments in paved areas must be done as the paving operation proceeds, VID typically has a crew working at the same time the Contractor is performing the paving operations. If VID is not able to perform the work due to an unforeseen circumstance, the Contractor shall adjust those facilities to grade on behalf of VID as the paving work is being done. Because the quantity of VID covers to be adjusted depends on the availability of VID crews to perform the work, the quantity in the Bid is a rough estimate for bidding purposes only. Stipulated unit prices may be included in the Bid to eliminate for all bidders the risk of including prices for those items of work in the bid and not getting the work.

Within five (5) Working Days of placing the asphalt concrete, the Contractor shall complete the adjustment of the manholes and miscellaneous utility frames and covers to grade.

Immediately after the overlay operation, the Contractor shall mark all manhole and miscellaneous utility frames and cover locations with paint for ease of locating them in case of an emergency.

The tops of reset manholes and miscellaneous utility frames and covers shall meet the smoothness requirements as specified in Subsection 302-5.12 (“ Smoothness.”) and be reconstructed per the City of Vista Standard Drawing SWR-33 (“ SEWER MANHOLE RECONSTRUCTION”).

403-5 PAYMENT.

Modify this subsection to read as follows:

Payment for adjusting manhole frames and covers to grade, where the difference between the lowest point of manhole riser removal to the final elevation of the top of the frame is less than 15 inches or where the adjustment is accomplished by adjustment rings only, will be made 08/12/2025

Superior Asphalt Performance
ACE XP Polymer Fiber™ is a true achievement in additive technology to enhance asphalt concrete performance.

ACE XP Polymer Fiber™ extends pavement service life by dramatically improving the dynamic modulus of the asphalt layer and increasing the asphalt's resistance to cracking and rutting (distresses that may cause premature failure). To create ACE XP Polymer Fiber™, high -strength man -made “ aromatic poly amide” or Aramid Fibers are bundled and coated with Sasobit® wax to create an asphalt concrete additive that is simple to mix with any WMA or HMA in through a drum and or batch asphalt operation. The 3-dimensional reinforcement throughout the asphalt layer increases the asphalt’s re sistance to cracking, rutting, and fatigue while providing improved ESAL (Equivalent Single Axel Load) capacity.

ACE XP Polymer Fiber™ is engineered for performance.

Aramid Fibers are used extensively in many industries an d applications including ballistic protection, heat & cut protection, automotive, ropes & cables, conveyor belts, etc. However, i t takes a special fiber to withstand the extreme production temperatures of asphalt concrete without changes occurring to the reinforcement properties of the fiber.

That is why ACE XP Polymer Fiber™ uses aramid fibers exclusively . Aramid is a unique man -made, high-strength polymer fiber boasting high tensile strengths over 400,000 psi (5 x steel), a superior stress/strain relat ionship, and decomposition temperatures of 932oF (well above asphalt mixing temperatures of 400oF). Both ¾” long and 1.5” long fiber lengths are available for superior long-term performance.

Superior Asphalt Performance

How does ACE XP Polymer FiberTM reinforce asphalt concrete?

As the standard dosage of ACE XP Polymer Fiber™ is mixed into WMA or HMA (4.2 ounces of ACE Fiber™ per ton of asphalt concrete), the Sasobit ® wax melts at approximately 170oF, releasing millions of Aramid Fibers uniformly throughout each ton of asphalt concrete. Aramid is a unique polymer fiber that has hair -like fibrils which root tenaciously in the liquid asphalt binder and bond to small granules and aggregates. Through the combination of high tensile strength, strength at low strain, and "fiber anchoring" ACE XP Polymer Fiber™ delivers reinforcement to asphalt concrete and enhances the strength and durability of the finished asphalt concrete mix.

ACE XP Polymer Fiber™ (Before & After)
Aramid Fibers have fibrils that anchor and bond
themselves within the liquid asphalt binder and
granules increasing the tensile strength of the mix.

Superior Asphalt Performance
Does ACE XP Polymer FiberTM Lab performance translate to Field performance?

During summer months when asphalt pavements get hot and "soften" it is easier for wheel loads to create ruts in the surface, but not when millions of Aramid Fibers are rooted in the asphalt because they provide resistance to the “flow” of the soft binder. Likewise, in winter months when asphalt pavements are cold, and the asphalt shrinks and expands, ACE XP Polymer Fiber™ provides added tensile strength to the asphalt and enhance s the pavement ’s resistance to thermal cracking as well as fatigue cracking that tends to happen during at higher temperatures.

Superior Asphalt Performance
Is ACE XP Polymer FiberTM reinforced asphalt concrete easy to pave with?

Absolutely! Once ACE XP Po lymer FiberTM is dispersed
throughout the asphalt mix, millions of light-weight aramid fibers go to work reinforcing the asphalt mix, but they do not cause any changes to the working characteristics of asphalt mix. ACE XP Polymer FiberTM reinforced asphalt concrete goes through the paver in the exact same way, it can be raked and shoveled the in the same way and can be compacted the same way using the same equipment. All laydown procedures are seamless, making adoption of the technology easy and cost effective. Add ACE XP Polymer FiberTM to overlays and new pavements alike.

How do I assure the right amount of ACE FiberTM gets added to my asphalt?

Although ACE XP Polymer Fiber TM is engineered with controlled amounts of Sasobit ® Wax in order to efficiently disperse the Aramid Fiber throughout the asphalt mix, Surface Tech recognizes the importance of proper dosage an d mixing of the ACE XP Polymer Fiber TM during production at the asphalt plant. ACE XP Polymer FiberTM is easily included into the asphalt mixing process at both batch and drum plant facilities. A simple-to-operate Line-Vac® Compressed Air Delivery System or the Automated Micro Doser MD3 + is used to transport the appropriate amount of ACE XP Polymer Fiber TM to either the mixing drum of a drum plant or the pug mill/weigh hopper of a batch plant.

Once ACE Fiber TM is fed into mixing drum, t he Sasobit ® wax becomes f ully soluble in the liquid asphalt binder and releases millions aramid fibers to be dispersed throughout the heated aggregate and Recycled Asphalt Pavement (RAP) prior to the injection of the liquid asphalt binder. The addition of a single dose (4.2 ounces per ton of asphalt) of ACE XP Polymer FiberTM does not change the asphalt volumes or require any change to the job mix formula (JMF).

Every ACE XP Polymer Fiber TM sale provides a robust QA/QC program to ensure th e right amount of ACE XP Polymer FiberTM makes its way into each ton of asphalt concrete for every project. Asphalt producers may choose from the following options to perform Certified ACE XP Polymer Fiber TM mixing at their plants:

Plant Introduction : Continuous Drum Plant /
FORTA-FI reinforcement fiber will be added at a rate
of one pound per ton of asphalt concrete.

A. For projects larger than 3,000 tons with daily
production quantities exceeding 1,000 tons per
day, it is recommended that fiber-reinforcement
be added using a fiber metering device (FMD).

The FMD will be supplied by Pacific GeoSource
and will be accompanied by an experienced
technician who will set up and run the machine
for the duration of the project. If an FMD is
purchased or leased, certified personnel from
Pacific GeoSource will provide fiber feeding
training and certification for plant personnel as
needed.

Figure 1: Voyager Portable Fiber Feeder.

1. The FMD requires a 240/480 volt electrical
hookup at the plant and should be installed and
tested prior to the start of asphalt production.

2. The FMD holds 300 pounds of fiber -
reinforcement in the storage hopper at one
time. Fiber should be loaded into the FMD in
bulk without any plastic bags. During
production, the hopper should be refilled prior
to reaching a minimum fiber quantity of 30
pounds.

3. The FMD is a weigh-in-motion drum and blower
system which utilizes highly sensitive load cells
to precisely meter and dispense the fiber. This
innovative fiber feeding system certifies the
feed rate matches the plant production rate
ensures a dosage rate of one pound per ton .

Fiber metering data is recorded and can be
downloaded from the device as required.

4. Fiber-reinforcement is fed from the FMD into
the drum via a flexible 4 -in clear hose through
the RAP port or other suitable entry point. The
fiber injection point should be after fines
collection and before the addition of liquid
asphalt, so that mixing may occur within the hot
aggregate prior to coming in contact with liquid
binder.

5. A minimum plant production temperat ure of
220°F is recommended.

B. For projects smaller than 3,000 tons, it is
recommended that fiber be fed manually via
one of two procedures.

One Pound Bags

1. Place individual one -pound bags onto the
recycled asphalt pavement (RAP) belt at a rate
matching the output of the plant in tons per
hour (TPH) per Equation 1.

Equation 1:
3600/Tons per Hour
For example, for an operation at 300 TPH, the
dosage rate is
3600/300 = 12 (place 1 bag every 12 seconds)

Figure 2: One pound bags on RAP belt.

2. Plastic bag will melt instantly when bag enters
drum and fibers will disperse into the mix. A
minimum plant production temperature of
275°F is recommended to fully mel t the plastic
bag.

3. Adding multiple one-pound bags at once is not
recommended.

Little Shot Fiber Feeder

1. Provided by Pacific GeoSource on a short -term
lease, the Little Shot is a small portable unit
which requires an air compressor and a 4 -in
diameter hose to direct flow of loose fibers
through the RAP port.

Figure 3: Little Shot™ Fiber Feeder.

2. The Little Shot should be used when the
temperatures inside the drum at the RAP
entrance are insufficient to immediately melt
the plastic bag to release the fiber. Scenarios in
which this could occur include warm mix
processes where drum temperatures are less
than 315 °F or high and/or saturated RAP
contents.

3. Individual one -pound bags of FORTA -FI are
opened and feed into the Little Shot at a rate
matching the output of the plant (see part 1
above).

Plant Introduction : Batch Plant /
FORTA-FI reinforcement fiber will be added at a rate
of one pound per ton of asphalt concrete.

One Pound Bags

1. Add individual one -pound bags to the
aggregate in the weigh hopper . Plant
operations are typically unaffected, and
modifications are not needed. However,
depending on plant operations, slight
modifications to dry or wet mixing times may be
required.

2. One-pound bags are to be added to match
batch plant production. For example, for a
batch operation of 3 tons, three bags of FORTA-
FI would be required to meet the dosage of one
pound per ton.

3. The plastic bag will melt, and fibers will
disperse into the mix.

Figure 4: Manual Bag Feed at Batch Plant.

Big Shot Fiber Feeder

1. Provided by Pacific GeoSource by lease or
available for purchase, the Big Shot Fiber
Feeder unit requires an air compressor and 8 -
in PVC piping to direct flow of 1 -lb fiber bags
into the weigh hopper. Plant operations are
typically unaffected, and modifications are not
needed. However, depending on plant
operations, slight modifications to dry or wet
mixing times may be required.

2. The correct number of individual one -pound
bags of FORTA -FI are fed simultaneously into
the Big Shot based on batch size (see part 1.i.
above).

Quality Assurance /
Asphalt producer should visually inspect the mix
prior to sending trucks to the jobsite to ensure
proper blending of fiber into the asphalt has
occurred. Inspection should take place at the drum
discharge point and also in the back of the first
trucks to leave the plant. Verify fiber dispersion a
minimum of every two hours.

Observe mix for undispersed clips and aramid
bunches. Spot check asphalt mix in the truck and
while paving. Look carefully as binder -soaked clips
are difficult to see.

If unblended fibers are visible, minor adjustments to
mixing operations may be needed to correct. This
may be accomplished by adjusting the angle of the
loose fiber feed tube, raising production

temperature (when high RAP% is used), or lowering
the TPH production rate, with the ultimate goal of
increasing the time for fibers to disperse in the hot
aggregate prior to injection of liquid binder.

Record fiber feeding data manually or using the FMD
automatic data logging system to provide
verification of fiber dosage as needed to comply
with project specifications.

Fiber supplier will provide technical assistance
during feeding operations and support during
construction as needed.

AVISO
Proyecto de mejoramiento de
banquetas para el año 2022
No habrá estacionamiento
De las 7:00am hasta las 5:00 pm
Sentimos
la molestia
Su lado de la calle debe estar libre de vehículos estacionados el día:
para que e
l contratista pueda construir nuevas banquetas y entradas de autos en su vecindario.

Ya que se pr
ohibirá el estacionamiento en la calle y su entrada temporalmente, estacione su coche en el lado opuesto de la calle o en una calle cercana antes del horario mencionado en este aviso para prevenir que su carro sea remolcado.

LOS CO
CHES ESTACIONADOS SERÁN REMOLCADOS
No se permi
tirá el uso de su entrada de carro hasta que se concluya la construcción de la banqueta. Por favor obedezca todas las indicaciones de la zona de construcción.

Por favor no permita que el agua corra por el camino de la entrada, sobre la banqueta, o en el canal durante la construcción de la calle. Esto ayudará que el concreto se seque. Si la colección de basura está programada para esa fecha, por favor asegúrese que los botes de su basura estén afuera a las 6:00am. Se proporcionará acceso a su casa para la colección de la basura.

Bajo c
ondiciones normales de clima, generalmente su calle debe ser accesible después de las 5:00pm. Sin embargo, problemas imprevistos y retrasos de construcción podrían afectar la fecha de terminación del proyecto. Si el trabajo se retrasa por lluvia o por circunstancias imprevistas, será reprogramado y se le notificará en un lapso de 2 semanas.

Estam
os conscientes de las molestias causadas por acceso limitado a su casa.

Por favor, comprenda que las molestias ocasionadas en este tiempo son temporales y menores en comparación con la comodidad de tener banquetas nuevas en su comunidad.
