® 4. AMERICANS WITH DISABILITIES ACT (ADA) STANDARDS (Applicable to ALL New Construction and Alteration Projects).
All public entities are required to follow the Americans with Disabilities Act of 1990 (ADA), regardless of funding sources. Wherever pedestrian
facilities are intended to be a part of the transportation facility, federal regulations require that those pedestrian facilities meet ADA standards.
All new construction or alteration of existing transportation facilities must be designed and constructed to be accessible to and usable by
persons with disabilities per Title II of the ADA (28 CFR Part 35.151) and Section 504 regulations (49 CFR Part 27.7(c)).
Neither cost nor schedule are factors in determining whether the ADA standards can be met, nor are they factors in determining the feasibility
of complying with the standard. An alteration project must be planned, designed, and constructed so that the required accessibility
improvements occur at the same time as the alteration.
The following are not considered Alteration Projects: Spot Pavement Repair, Liquid -Asphalt Sealing, Chip Seal (BST), Crack Sealing, and
Lane Restriping that does not alter the usability of the shoulder.
If there is uncertainty as to whether a project meets the definition of an alteration project, WSDOT's Construction Representative and the
Agency's Representative shall consult with WSDOT's Regional ADA Coordinator.
If a situation is encountered where it may not be possible to fully meet the applicable accessibility requirements during alterations of existing
facilities, WSDOT's Construction Representative and the Agency's Representative shall consult with WSDOT's Regional ADA Coordinator in
order to develop a workable solution to meet the accessibility requirements to the maximum extent feasible (MEF).
® 5. ADA FEATURE AS -BUILT MEASUREMENTS (Applicable to ALL New Construction and Alteration Projects).
The Agency shall be responsible for providing WSDOT with electronic As -Built records of all ADA feature improvements completed on the
State Highway(s) in the Construction Agreement. The survey work shall include but not be limited to completing the measurements, recording
the required measurements and completing other data fill-ins found on the ADA Measurement Forms, and transmitting the electronic Forms to
WSDOT's Construction Representative. The ADA Measurement Forms are found at the following website location:
httollwww.wsdot.wa.00vlDesign/ADAGuidance.litn7. In the instance where an ADA Feature does not meet accessibility requirements, all

Agency. Extensions will be allowed provided they produce the same results, including
ride, density, and surface texture as obtained by the primary screed. Extensions without
augers and an internally heated vibratory screed shall not be used in the Traveled Way.
When specified in the Contract, reference lines for vertical control will be required. Lines
shall be placed on both outer edges of the Traveled Way of each Roadway. Horizontal
control utilizing the reference line will be permitted. The grade and slope for intermediate
lanes shall be controlled automatically from reference lines or by means of a mat
referencing device and a slope control device. When the finish of the grade prepared for
paving is superior to the established tolerances and when, in the opinion of the
Engineer, further improvement to the line, grade, cross-section, and smoothness can
best be achieved without the use of the reference line, a mat referencing device may be
substituted for the reference line. Substitution of the device will be subject to the
continued approval of the Engineer. A joint matcher may be used subject to the approval
of the Engineer. The reference line may be removed after the completion of the first
course of HMA when approved by the Engineer. Whenever the Engineer determines that
any of these methods are failing to provide the necessary vertical control, the reference
lines will be reinstalled by the Contractor.
The Contractor shall furnish and install all pins, brackets, tensioning devices, wire, and
accessories necessary for satisfactory operation of the automatic control equipment.
If the paving machine in use is not providing the required finish, the Engineer may
suspend Work as allowed by Section 1-08.6. Any cleaning or solvent type liquids spilled
on the pavement shall be thoroughly removed before paving proceeds.
5-04.3(3)D Material Transfer Device or Material Transfer Vehicle
A Material Transfer Device/Vehicle (MTD/V) shall only be used with the Engineer's
approval, unless other -wise required by the contract.
Where an MTD/V is required by the contract, the Engineer may approve paving without
an MTD/V, at the request of the Contractor. The Engineer will determine if an equitable
adjustment in cost or time is due.
When used, the MTD/V shall mix the HMA after delivery by the hauling equipment and
prior to laydown by the paving machine. Mixing of the HMA shall be sufficient to obtain a
uniform temperature throughout the mixture. If a windrow elevator is used, the length of
the windrow may be limited in urban areas or through intersections, at the discretion of
the Engineer.
To be approved for use, an MTV:
1. Shall be self-propelled vehicle, separate from the hauling vehicle or paver.
2. Shall not be connected to the hauling vehicle or paver.
3. May accept HMA directly from the haul vehicle or pick up HMA from a windrow.
4. Shall mix the HMA after delivery by the hauling equipment and prior to
placement into the paving machine.

accordance with the manufacturer's recommendations. When ordered by the Engineer
for any roller planned for use on the project, the Contractor shall provide a copy of the
manufacturer's recommendation for the use of that roller for compaction of HMA. The
number and weight of rollers shall be sufficient to compact the mixture in compliance
with the requirements of Section 5-04.3(10). The use of equipment that results in
crushing of the aggregate will not be permitted. Rollers producing pickup, washboard,
uneven compaction of the surface, displacement of the mixture or other undesirable
results shall not be used.
5-04.3 4 Preparation of Existing Paved Surfaces
When the surface of the existing pavement or old base is irregular, the Contractor shall
bring it to a uniform grade and cross-section as shown on the Plans or approved by the
Engineer.
Preleveling of uneven or broken surfaces over which HMA is to be placed may be
accomplished by using an asphalt paver, a motor patrol grader, or by hand raking, as
approved by the Engineer.
Compaction of preleveling HMA shall be to the satisfaction of the Engineer and may
require the use of small steel wheel rollers, plate compactors, or pneumatic rollers to
avoid bridging across preleveled areas by the compaction equipment. Equipment used
for the compaction of preleveling HMA shall be approved by the Engineer.
Before construction of HMA on an existing paved surface, the entire surface of the
pavement shall be clean. All fatty asphalt patches, grease drippings, and other
objectionable matter shall be entirely removed from the existing pavement. All
pavements or bituminous surfaces shall be thoroughly cleaned of dust, soil, pavement
grindings, and other foreign matter. All holes and small depressions shall be filled with
an appropriate class of HMA. The surface of the patched area shall be leveled and
compacted thoroughly. Prior to the application of tack coat, or paving, the condition of
the surface shall be approved by the Engineer.
A tack coat of asphalt shall be applied to all paved surfaces on which any course of HMA
is to be placed or abutted; except that tack coat may be omitted from clean, newly paved
surfaces at the discretion of the Engineer. Tack coat shall be uniformly applied to cover
the existing pavement with a thin film of residual asphalt free of streaks and bare spots
at a rate between 0.02 and 0.10 gallons per square yard of retained asphalt. The rate of
application shall be approved by the Engineer. A heavy application of tack coat shall be

When the Proposal includes a pay item for crack sealing, seal all cracks'/4 inch in width
and greater.
Cleaning: Ensure that cracks are thoroughly clean, dry and free of all loose and foreign
material when filling with crack sealant material. Use a hot compressed air lance to dry
and warm the pavement surfaces within the crack immediately prior to filling a crack with
the sealant material. Do not overheat pavement. Do not use direct flame dryers. Routing
cracks is not required.
Sand Slurry: For cracks that are to be filled with sand slurry, thoroughly mix the
components and pour the mixture into the cracks until full. Add additional CSS-1 cationic
emulsified asphalt to the sand slurry as needed for workability to ensure the mixture will
completely fill the cracks. Strike off the sand slurry flush with the existing pavement
surface and allow the mixture to cure. Top off cracks that were not completely filled with
additional sand slurry. Do not place the HMA overlay until the slurry has fully cured.
The sand slurry shall consist of approximately 20 percent CSS-1 emulsified asphalt,
approximately 2 percent portland cement, water (if required), and the remainder clean
Class 1 or 2 fine aggregate per section 9-03.1(2). The components shall be thoroughly
mixed and then poured into the cracks and joints until full. The following day, any cracks
or joints that are not completely filled shall be topped off with additional sand slurry. After
the sand slurry is placed, the filler shall be struck off flush with the existing pavement
surface and allowed to cure. The HMA overlay shall not be placed until the slurry has
fully cured. The requirements of Section 1-06 will not apply to the portland cement and
sand used in the sand slurry.
In areas where HMA will be placed, use sand slurry to fill the cracks.
In areas where HMA will not be placed, fill the cracks as follows:

After the required amount of mineral materials, asphalt binder, recycling agent and anti -
stripping additives have been introduced into the mixer the HMA shall be mixed until
complete and uniform coating of the particles and thorough distribution of the asphalt
binder throughout the mineral materials is ensured.
When discharged, the temperature of the HMA shall not exceed the optimum mixing
temperature by more than 250F as shown on the reference mix design report or as
approved by the Engineer. Also, when a WMA additive is included in the manufacture of
HMA, the discharge temperature of the HMA shall not exceed the maximum
recommended by the manufacturer of the WMA additive. A maximum water content of 2
percent in the mix, at discharge, will be allowed providing the water causes no problems
with handling, stripping, or flushing. If the water in the HMA causes any of these
problems, the moisture content shall be reduced as directed by the Engineer.
Storing or holding of the HMA in approved storage facilities will be permitted with
approval of the Engineer, but in no event shall the HMA be held for more than 24 hours.
HMA held for more than 24 hours after mixing shall be rejected. Rejected HMA shall be
disposed of by the Contractor at no expense to the Contracting Agency. The storage
facility shall have an accessible device located at the top of the cone or about the third
point. The device shall indicate the amount of material in storage. No HMA shall be
accepted from the storage facility when the HMA in storage is below the top of the cone
of the storage facility, except as the storage facility is being emptied at the end of the
working shift.
Recycled asphalt pavement (RAP) utilized in the production of HMA shall be sized prior
to entering the mixer so that a uniform and thoroughly mixed HMA is produced. If there
is evidence of the recycled asphalt pavement not breaking down during the heating and
mixing of the HMA, the Contractor shall immediately suspend the use of the RAP until
changes have been approved by the Engineer. After the required amount of mineral
materials, RAP, new asphalt binder and asphalt rejuvenator have been introduced into

On areas where irregularities or unavoidable obstacles make the use of mechanical
spreading and finishing equipment impractical, the paving may be done with other
equipment or by hand.
When more than one JMF is being utilized to produce HMA, the material produced for
each JMF shall be placed by separate spreading and compacting equipment. The
intermingling of HMA produced from more than one JMF is prohibited. Each strip of HMA
placed during a work shift shall conform to a single JMF established for the class of HMA
specified unless there is a need to make an adjustment in the JMF.
5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA
For HMA accepted by nonstatistical evaluation the aggregate properties of sand
equivalent, uncompacted void content and fracture will be evaluated in accordance with
Section 3-04. Sampling and testing of aggregates for HMA accepted by commercial
evaluation will be at the option of the Engineer.
5-04.3(9) HMA Mixture Acceptance
Acceptance of HMA shall be as provided under nonstatistical, or commercial evaluation.
Nonstatistical evaluation will be used for the acceptance of HMA unless Commercial
Evaluation is specified.
Commercial evaluation will be used for Commercial HMA and for other classes of HMA
in the following applications: sidewalks, road approaches, ditches, slopes, paths, trails,
gores, prelevel, temporary pavement, and pavement repair. Other nonstructural
applications of HMA accepted by commercial evaluation shall be as approved by the
Engineer. Sampling and testing of HMA accepted by commercial evaluation will be at the
option of the Engineer.
The mix design will be the initial JMF for the class of HMA. The Contractor may request
a change in the JMF. Any adjustments to the JMF will require the approval of the
Engineer and may be made in accordance with this section.
HMA Tolerances and Adjustments
1. Job Mix Formula Tolerances — The constituents of the mixture at the time of
acceptance shall be within tolerance. The tolerance limits will be established as
follows:
For Asphalt Binder and Air Voids (Va), the acceptance limits are determined
by adding the tolerances below to the approved JMF values. These values
will also be the Upper Specification Limit (USL) and Lower Specification
Limit (LSL) required in Section 1-06.2(2)D2

5-04.3 9 C Mixture Acceptance — Nonstatistical Evaluation
HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the
Contracting Agency by dividing the HMA tonnage into lots.
5-04.3(9)C1 Mixture Nonstatistical Evaluation — Lots and Sublots
A lot is represented by randomly selected samples of the same mix design that will be
tested for acceptance. A lot is defined as the total quantity of material or work produced
for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be
equal to one day's production or 800 tons, whichever is less except that the final sublot
will be a minimum of 400 tons and may be increased to 1200 tons.
All of the test results obtained from the acceptance samples from a given lot shall be
evaluated collectively. If the Contractor requests a change to the JMF that is approved,
the material produced after the change will be evaluated on the basis of the new JMF for
the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot
in progress with a CPF less than 0.75, a new lot will begin at the Contractor's request
after the Engineer is satisfied that material conforming to the Specifications can be
produced.

Each lot of HMA produced under Nonstatistical Evaluation and having all constituents
falling within the toler-ance limits of the job mix formula shall be accepted at the unit
Contract price with no further evaluation. When one or more constituents fall outside the
nonstatistical tolerance limits in the Job Mix Formula shown in Table of Price Adjustment
Factors, the lot shall be evaluated in accordance with Section 1-06.2 to determine the
appro-priate CPF. The nonstatistical tolerance limits will be used in the calculation of the
CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup
samples of the existing sublots or samples from the Roadway shall be tested to provide
a minimum of three sets of results for evaluation.

5-04.3(9)C6 Mixture Nonstatistical Evaluation — Price Adjustments
For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated
CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The
NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The
total job mix compliance price adjustment will be calculated as the product of the NCMF,
the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix.
If a constituent is not measured in accordance with these Specifications, its individual
pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF).
5-04.3[9]C7 Mixture Nonstatistical Evaluation - Retests
The Contractor may request a sublot be retested. To request a retest, the Contractor
shall submit a written request within 7 calendar days after the specific test results have
been received. A split of the original acceptance sample will be retested. The split of the
sample will not be tested with the same tester that ran the original acceptance test. The
sample will be tested for a complete gradation analysis, asphalt binder content, and, at
the option of the agency, Va. The results of the retest will be used for the acceptance of
the HMA in place of the original sublot sample test results. The cost of testing will be
deducted from any monies due or that may come due the Contractor under the Contract
at the rate of $500 per sample.
5-04.3 (9)D Mixture Acceptance — Commercial Evaluation
If sampled and tested, HMA produced under Commercial Evaluation and having all
constituents falling within the tolerance limits of the job mix formula shall be accepted at
the unit Contract price with no further evaluation. When one or more constituents fall
outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the
lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate
CPF. The commercial tolerance limits will be used in the calculation of the CPF and the
maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the
existing sublots or samples from the street shall be tested to provide a minimum of three
sets of results for evaluation.
For each lot of HMA mix produced and tested under Commercial Evaluation when the
calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be
determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by
60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product

of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of
mix.
If a constituent is not measured in accordance with these Specifications, its individual
pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF).
5-04.3 10 HMA Compaction Acce tance
HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including
lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a
specified compacted course thickness greater than 0.10-foot, shall be compacted to a
specified level of relative density. The specified level of relative density shall be a
Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with
Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density).
The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The
specified level of density attained will be determined by the evaluation of the density of
the pavement. The density of the pavement shall be determined in accordance with
WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of
the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using
cores to determine density.
Tests for the determination of the pavement density will be taken in accordance with the
required procedures for measurement by a nuclear density gauge or roadway cores after
completion of the finish rolling.
If the Contracting Agency uses a nuclear density gauge to determine density the test
procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the
mix is placed and prior to opening to traffic.
Roadway cores for density may be obtained by either the Contracting Agency or the
Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches
minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by
the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166.
If the Contract includes the Bid item "Roadway Core" the cores shall be obtained by the
Contractor in the presence of the Engineer on the same day the mix is placed and at
locations designated by the Engineer. If the Contract does not include the Bid item
"Roadway Core" the Contracting Agency will obtain the cores.
For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor's
request after the Engineer is satisfied that material conforming to the Specifications can
be produced.
HMA mixture accepted by commercial evaluation and HMA constructed under conditions
other than those listed above shall be compacted on the basis of a test point evaluation
of the compaction train. The test point evaluation shall be performed in accordance with
instructions from the Engineer. The number of passes with an approved compaction
train, required to attain the maximum test point density, shall be used on all subsequent
paving.

by the Engineer.
Test Results
For a sublot that has been tested with a nuclear density gauge that did not meet the
minimum of 92 percent of the reference maximum density in a compaction lot with a
CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor may
request that a core be used for determination of the relative density of the sublot. The
relative density of the core will replace the relative density determined by the nuclear
density gauge for the sublot and will be used for calculation of the CPF and acceptance
of HMA compaction lot.
When cores are taken by the Contracting Agency at the request of the Contractor, they
shall be requested by noon of the next workday after the test results for the sublot have
been provided or made available to the Contractor. Core locations shall be outside of
wheel paths and as determined by the Engineer. Traffic control shall be provided by the
Contractor as requested by the Engineer. Failure by the Contractor to provide the
requested traffic control will result in forfeiture of the request for cores. When the CPF for
the lot based on the results of the HMA cores is less than 1.00, the cost for the coring
will be deducted from any monies due or that may become due the Contractor under the
Contract at the rate of $200 per core and the Contractor shall pay for the cost of the
traffic control.
5-04.300)A HMA Compaction — General Compaction Requirements
Compaction shall take place when the mixture is in the proper condition so that no
undue displacement, cracking, or shoving occurs. Areas inaccessible to large
compaction equipment shall be compacted by other mechanical means. Any HMA that
becomes loose, broken, contaminated, shows an excess or deficiency of asphalt, or is in
any way defective, shall be removed and replaced with new hot mix that shall be
immediately compacted to conform to the surrounding area.
The type of rollers to be used and their relative position in the compaction sequence
shall generally be the Contractor's option, provided the specified densities are attained.
Unless the Engineer has approved otherwise, rollers shall only be operated in the static
mode when the internal temperature of the mix is less than 175°F. Regardless of mix
temperature, a roller shall not be operated in a mode that results in checking or cracking
of the mat. Rollers shall only be operated in static mode on bridge decks.
5-04.3(10)6 HMA Compaction — Cyclic Density
Low cyclic density areas are defined as spots or streaks in the pavement that are less
than 90 percent of the theoretical maximum density. At the Engineer's discretion, the
Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will
follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for
any 500-foot section with two or more density readings below 90 percent of the
theoretical maximum density.

5-04.3 10 D HMA Nonstatistical Compaction
5-04.3 10 ❑1 HMA Nonstatistical Compaction — Lots and Sublots
HMA compaction which is accepted by nonstatistical evaluation will be based on
acceptance testing performed by the Contracting Agency dividing the project into
compaction lots.
A lot is represented by randomly selected samples of the same mix design that will be
tested for acceptance. A lot is defined as the total quantity of material or work produced
for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be
equal to one day's production or 400 tons, whichever is less except that the final sublot
will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction
will be at the rate of 5 tests per sublot per WSDOT T 738.
The sublot locations within each density lot will be determined by the Engineer. For a lot
in progress with a CPF less than 0.75, a new lot will begin at the Contractor's request
after the Engineer is satisfied that material conforming to the Specifications can be
produced.
HMA mixture accepted by commercial evaluation and HMA constructed under conditions
other than those listed above shall be compacted on the basis of a test point evaluation
of the compaction train. The test point evaluation shall be performed in accordance with
instructions from the Engineer. The number of passes with an approved compaction
train, required to attain the maximum test point density, shall be used on all subsequent
paving.
HMA for preleveling shall be thoroughly compacted. HMA that is used to prelevel wheel
ruts shall be compacted with a pneumatic tire roller unless otherwise approved by the
Engineer.
5-04.3(10)D2 HMA Compaction Nonstatistical Evaluation_- Acceptance Testing
The location of the HMA compaction acceptance tests will be randomly selected by the
Engineer from within each sublot, with one test per sublot.
5-04.3(10)D3 HMA Nonstatistical Compaction —Price Adjustments
For each compaction lot with one or two sublots, having all sublots attain a relative
density that is 92 percent of the reference maximum density the HMA shall be accepted
at the unit Contract price with no further evaluation. When a sublot does not attain a
relative density that is 92 percent of the reference maximum density, the lot shall be
evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The
maximum CPF shall be 1.00, however, lots with a calculated CPF in excess of 1.00 will
be used to offset lots with CPF values below 1.00 but greater than 0.90. Lots with CPF
lower than 0.90 will be evaluated for compliance per 5-04.3(11). Additional testing by
either a nuclear moisture -density gauge or cores will be completed as required to
provide a minimum of three tests for evaluation.
For compaction below the required 92% a Non -Conforming Compaction Factor (NCCF)
will be determined. The NCCF equals the algebraic difference of CPF minus 1.00
multiplied by 40 percent. The Compaction Price Adjustment will be calculated as the

5-04.301) Reiec#_Work
5-04.3 11 A Re'ect Work General
Work that is defective or does not conform to Contract requirements shall be rejected.
The Contractor may propose, in writing, alternatives to removal and replacement of
rejected material. Acceptability of such alternative proposals will be determined at the
sole discretion of the Engineer. HMA that has been rejected is subject to the
requirements in Section 1-06.2(2) and this specification, and the Contractor shall submit
a corrective action proposal to the Engineer for approval.
5-04.301)B Resection by Contractor
The Contractor may, prior to sampling, elect to remove any defective material and
replace it with new material. Any such new material will be sampled, tested, and
evaluated for acceptance.
5-04.3(11)C Rejection Without Testing (Mixture or Compaction)
The Engineer may, without sampling, reject any batch, load, or section of Roadway that
appears defective. Material rejected before placement shall not be incorporated into the
pavement. Any rejected section of Roadway shall be removed.
No payment will be made for the rejected materials or the removal of the materials
unless the Contractor requests that the rejected material be tested. If the Contractor
elects to have the rejected material tested, a minimum of three representative samples
will be obtained and tested. Acceptance of rejected material will be based on
conformance with the nonstatistical acceptance Specification. If the CPF for the rejected
material is less than 0.75, no payment will be made for the rejected material; in addition,
the cost of sampling and testing shall be borne by the Contractor. If the CPF is greater
than or equal to 0.75, the cost of sampling and testing will be borne by the Contracting
Agency. If the material is rejected before placement and the CPF is greater than or equal
to 0.75, compensation for the rejected material will be at a CPF of 0.75. If rejection
occurs after placement and the CPF is greater than or equal to 0.75, compensation for
the rejected material will be at the calculated CPF with an addition of 25 percent of the
unit Contract price added for the cost of removal and disposal.
5-04.3(11)D Resection -A Partial Sublot
In addition to the random acceptance sampling and testing, the Engineer may also
isolate from a normal sublot any material that is suspected of being defective in relative
density, gradation or asphalt binder content. Such isolated material will not include an
original sample location. A minimum of three random samples of the suspect material
will be obtained and tested. The material will then be statistically evaluated as an
independent lot in accordance with Section 1-06.2(2).
5-04.301)E Resection - An Entire Sublot
An entire sublot that is suspected of being defective may be rejected. When a sublot is
rejected a minimum of two additional random samples from this sublot will be obtained.
These additional samples and the original sublot will be evaluated as an independent lot
in accordance with Section 1-06.2(2).
