**401.04 Mixing Plant.** [Delete the text and substitute the
following:]{.underline}

**(2) Dust collector.** AASHTO M 156, Requirements for All Plants,
Emission Controls is amended as follows:

Equip the plant with a dust collector. Dispose of the collected
material. In the case of baghouse dust collectors, dispose of the
collected material or return the collected material uniformly.

Use of baghouse fines in asphalt concrete mixes requires approval unless
included as part of the approved job-mix formula. If baghouse fines are
approved for use, batch or continuous mix plants will meter it by volume
or mass into the mixing chamber.

**401.08 Asphalt Preparation.** [Delete the Subsection and substitute
the following:]{.underline}

Uniformly heat the asphalt binder to provide a continuous supply of the
heated asphalt binder from storage to the mixer. Do not heat asphalt
binder above 185 ºC.

**401.09 Aggregate Preparation.** [Delete the Subsection and substitute
the following:]{.underline}

Adjust the aggregate moisture to at least 4 percent by mass of
aggregate. Mix the lime uniformly with the aggregate before introducing
the aggregate into the dryer or dryer drum. Use calibrated weighing or
metering devices to measure the amount of lime and moisture added to the
aggregate.

For batch plants, heat, dry, and deliver aggregate for pugmill mixing at
a temperature sufficient to produce a mix temperature within the
approved range. Adjust flames used for drying and heating to prevent
damage to and contamination of the aggregate.

Control plant operations so the moisture content of the mix behind the
paver is 0.5 percent or less according to AASHTO T 255.

Add lime to the aggregate by Method A, B, or C below.

> **Method A -** Add lime to the combined cold feed aggregate using an
> enclosed in-line cold feed mechanical pugmill mixer. Use a twin-shaft,
> continuous mixing pugmill with adjustable mixing paddles. Adjust the
> retention time of the mixture in the pugmill so no unmixed lime is
> visible after the lime and aggregate exit the pugmill.
>
> **Method B -** Add lime to the produced aggregates during stockpiling
> using a pugmill. Add twenty-five (25) percent of the lime to be added
> to the coarse aggregate stockpile, and add seventy-five (75) percent
> of the lime to be added to the fine aggregate stockpile. When more
> than two stockpiles are used, include the distribution of lime per
> stockpile in the mix design.
>
> A minimum moisture content of two (2) percent by dry weight for coarse
> aggregate and four (4) percent by dry weight for fine aggregate is
> required at the time the aggregates and lime are mixed.
>
> **Method C -** Use a lime slurry consisting of one part lime and three
> parts water. Equipped the plant with a mixing unit to allow mixing of
> the slurry and aggregate prior to entering the dryer or dryer drum.
>
> Adjust the moisture of the coarse and fine aggregates, or combination
> of aggregates, to obtain uniform coating of the aggregate with the
> lime.

Prior to the production of Superpave hot asphalt concrete pavement,
obtain approval of synchronized metering and weighing devices used to
introduce a constant rate of lime and water.

  -----------------------------------------------------------------------
  For **all 4R projects** add the following to Subsection 401.13 (also
  include detail CM634-50):

  -----------------------------------------------------------------------

**401.13 Placing and Finishing**. [Add the following to the fifth
paragraph]{.underline}:

For simple curve widening locations (widening only on one side) shift
the centerline joint location such that the final layer is midway
between the normal edge of shoulders. The shift from the staked
centerline will be towards the widened lane one-half the total curve
widening specified for the given station as shown in the plans.

  -----------------------------------------------------------------------
  **OR** For **all 3R projects** add the following to Subsection 401.13:

  -----------------------------------------------------------------------

**401.13 Placing and Finishing**. [Delete the fifth paragraph and
substitute the following]{.underline}:

Make the longitudinal joint in the top layer along the existing striped
centerline, as recorded under Subsection 152.03(n), or at the lane lines
of roadways with more than two lanes.

  -----------------------------------------------------------------------
  Add the following to Subsection 401.13 when the hot mix haul is
  anticipated to be long. Also be sure to include the pay item 62202-1000
  for "Material Transfer Vehicle".

  -----------------------------------------------------------------------

**401.13 Placing and Finishing**. [Add the following]{.underline}:

Use a Materials Transfer Vehicle (MTV) with storage and remixing
capabilities on all mainline construction when placing asphalt concrete
mixtures. The MTV will independently remix and deliver mixture from the
hauling equipment to the paving equipment.

Furnish an MTV with the following capabilities:

> • An unloading system to receive mixtures from the hauling equipment.
>
> • A minimum storage capacity of 13 tons with a remixing system in the
> MTV storage bin.
>
> • A discharge conveyor to deliver the mixture to the paver hopper.
>
> • The MTV system cannot exceed maximum legal loadings on structures.

Acceptable Material Transfer Vehicles are:

> • Barber Greene MTV-3500
>
> • Roadtec SB-1500
>
> • Roadtec SB-2500

In the event the MTV malfunctions during paving operations, the
Contractor must suspend paving, however hot mix in transit and stored in
the silo at the time of breakdown may be placed without the use of an
MTV. Do not resume hot mix placement until the MTV is operational.

**401.14 Compacting.** [Delete the first sentence of the first paragraph
and substitute the following:]{.underline}

Furnish at least 3 rollers. Furnish one roller each for breakdown,
intermediate, and finish rolling. At least one roller will be
pneumatic-tired. Size the rollers to achieve the required results.
Operate rollers according to the recommendation of the manufacturer.
Diesel fuel will not be used as a release agent with any roller used to
compact the asphalt mix.

**401.16 Pavement Smoothness/Roughness.** [Delete the Subsection and
substitute the following:]{.underline}

**401.16 Pavement Roughness**. Measure the roughness of the final paved
surface course within 21 days after final rolling of the completed
roadway paving, and before placement of any surface treatment. In
addition to meeting the pavement roughness type requirements, construct
all pavement surfaces to meet the requirements of Type V pavement
roughness.

**(a) International roughness index (IRI).**

> **Equipment.** Provide an ASTM E 950, class 1, high speed inertial
> profiling system meeting all the requirements and specifications found
> in AASHTO MP 11, with emphasis on the filter and sampling intervals
> specified in sections 4.2.3 and 4.2.4. Certify profiler in accordance
> with AASHTO PP 49. Operate profiler in accordance with AASHTO PP 50.
> At the pre-construction meeting and before profiling provide copies of
> profiling system to be used and certification(s). Display a current
> decal on the equipment indicating the expiration date of
> certification(s).
>
> **Personnel.** Certify operator in accordance with AASHTO PP 49. At
> the pre-construction meeting and before profiling provide copies of
> operator certification(s).
>
> **Measuring.** Measure the pavement profile in both wheel paths, two
> longitudinal traces with a sensor path spacing of 165-180 centimeters,
> centered in the traveled way of the lane. For each lane, submit on
> disk one continuous raw IRI data file (\*.ERD) for the "left" and
> "right" wheel paths to the CO immediately after profiling. Use
> profiler's automatic start/stop activation when collecting data. The
> CO must coordinate and observe profiling operations. Non-continuous
> data files will not be accepted. Submit inertial profiler setup
> parameters (e.g. filters, sampling interval, and segment length,
> etc.). Measure excluded areas according to Type V pavement roughness.
>
> **Evaluation.** The CO will review, analyze and may perform
> verification testing on all IRI measurements. The CO will analyze
> profile data using Profile Viewer and Analysis (ProVAL) software. The
> CO's analysis will be used to determine the Mean Roughness Index
> (MRI), and the associated roughness pay factor.
>
> Defective areas include the following:

-   Bumps or Localized Roughness Areas (LRA) in excess of 5.0
    millimeters in 7.62 meters, using ProVAL's Localized Roughness
    Analysis.

-   0.1-lane kilometer MRI greater than a Ride Quality Threshold of
    1.657 meters/kilometer, using ProVAL's Smoothness Assurance
    Analysis.

Correct defective areas according to paragraph (c) below.

> If the final MRI for the entire traveled way is greater than 1.973
> meters/kilometer using ProVAL's Ride Statistics Analysis, the traveled
> way is in reject. Correct rejected traveled way according to paragraph
> (c) below.
>
> An MRI value will be determined for each 0.1-lane kilometer of
> traveled way. The total traveled way will be analyzed including
> partial segments less than 0.1-lane kilometer. Exclusion areas are
> 7.62 meters on either side of Beginning and End of Project, cattle
> guards, and bridges. These areas will be excluded from the calculation
> of MRI and determination of localized roughness.
>
> **(1) Type III pavement roughness (IRI measurements for reconstructed
> and new roads).** Measure the roughness of the final paved surface
> course. Pay factors from Table 401-3 will be used in conjunction with
> the histogram printout from ProVAL's Smoothness Assurance Analysis.
> The final pay factor (PF~rough~) is equal to the sum of the products
> of the individual pay factors indicated in Table 401-3 multiplied by
> ProVAL's corresponding histogram percentages, divided by 100.
> Calculate the final pay factor to two decimal places.

> one operation.

**(b)** **Type V pavement roughness (straightedge measurement).** Use a
3 meter metal straight edge to measure at right angles and parallel to
the centerline. Type V localized roughness areas (LRA) are surface
deviations in excess of 6 millimeters in 3 meters between any two
contacts of the straightedge with the surface.

**(c) Defective area correction.** Correct defective areas from
paragraphs (a) or (b) above. Obtain approval from the CO for correction
of defected areas as well as the method of correction. When grinding is
allowed, the area ground shall not exceed 67 square meters per location,
and is limited to 6 locations per lane kilometer. Grinding depth is
limited to 12.5% of the design pavement thickness. Grinding in excess of
these limits is not an acceptable method of correction unless it is
accompanied by an overlay or a single-course surface treatment over the
entire length of the project.

If grinding is allowed, grind the pavement surface with a diamond blade
machine and apply a surface treatment according to Sections 409 or 410
as approved by the CO. The endpoints of the areas where a grinder is to
be applied must be optimized using ProVAL.

If corrections are allowed, re-measure the pavement profile. Data from
the re-measurement and re-analysis will be used to determine PF~rough~
in accordance with Table 401-3 or Table 401-4.

If corrections are not allowed, no adjustment will be made to the final
pay factor (PF~rough~) determined from Table 401-3 or Table 401-4. A
dollar adjustment per remaining bump when grinding is not allowed will
be determined according to subsection 401.19.

Defective area corrections and surface treatments shall be provided at
no cost to the Government.

**401.17 Acceptance**. [Delete the second paragraph and substitute the
following:]{.underline}

Asphalt binder will be evaluated under Subsections 106.04, and 702.09,
and Table 401-5.

**Payment**

**401.19** [Delete the Subsection and substitute the
following:]{.underline}

The accepted quantities will be paid at the contract price per unit of
measurement for the Section 401 pay items listed in the bid schedule
except the Superpave hot asphalt concrete pavement contract unit bid
price will be adjusted according to Subsections 106.05, 401.16, and
Table 401-5. Payment will be full compensation for the work prescribed
in this Section. See Subsection 109.05.

Payment for Superpave hot asphalt concrete pavement will be made at a
price determined by multiplying the contract unit bid price by the
material pay factor. The material pay factor is calculated as follows:

A1 = \[(PF~Superpave~ -- 1) + (PF~PG~ -- 1)\]

where:

A1 = Material pay factor.

> PF~Superpave~ = Pay factor for Superpave hot asphalt concrete
> pavement. PF~Superpave~ is the lowest single pay factor determined for
> asphalt binder content, VMA, and core density.
>
> PF~PG~ = Pay factor for asphalt binder. The PF~PG~ formula is as
> follows:
>
> PF~PG~ = (PF~1~ + PF~2~ + PF~3~ + ....PF~n~) / n
>
> where:
>
> PF~\#~ = For each sample, the lowest pay factor determined from any
> test in Table 401-5. If the lowest pay factor for a sample is in
> reject, the sample's pay factor is zero.
>
> n = Number of samples tested.

If either the pay factor for the asphalt binder (PF~PG~) or the pay
factor for Superpave hot asphalt concrete pavement (PF~Superpave~) is
below 0.75, the lot for Superpave hot asphalt concrete pavement is in
reject.

When the bid schedule contains a pay item for Superpave hot asphalt
concrete pavement, type III and type IV pavement roughness, a separate
pay adjustment will be made for pavement roughness calculated as
follows:

Type III and Type IV Pay Adjustment = 24,800 (PF~rough~ - 1.00)(L) --
(NLRA x 300)

where:

> PF~rough~ = Pay factor from Table 401-3 or Table 401-4.
>
> L = Total project length in lane kilometers of traveled way. Measure
> the project length to 2 decimals.
>
> NLRA = Number of localized roughness areas (bumps) remaining in final
> traveled way as determined by ProVAL and Type V measurements.

^(1)^ Use AASHTO T 308, Method A. Calculate the asphalt binder content
by weighing the sample before and after the burn using a calibrated
external balance. Modify AASHTO T 308, parts 8.2 and 10.2 to allow the
use of AASHTO T 255, Total Evaporable Moisture Content of Aggregate by
Drying.

^(2)^ Cut core samples from the compacted pavement and carefully remove
using a core retriever. Fill and compact the sample holes with asphalt
concrete mixture. Cores shall be 150 millimeters in diameter. Perform
specific gravity, and thickness tests on the cores and deliver to the CO
after testing is completed. Label cores and protect from damage due to
handling or alteration due to temperature during storage or transfer. If
more than 2.0 percent of water volume is absorbed as determined by
AASHTO T 166, use AASHTO T 331 in lieu of AASHTO T 275.

^(3)^ After production paving has begun, use the Maximum specific
gravity value (AASHTO T 209) for each day to adjust the percent
compaction for the cores that represent that day's paving.
