These devices may be used as a safety enhancement to flaggers on an hour-for-hour basis. AFADs
shall meet the following requirements:
(a) All AFAD applications shall meet the requirements of the applicable sections of the current
edition of the Manual on Uniform Traffic Control Devices (MUTCD).

unrestricted traffic flow immediately.
(e) Each AFAD will be considered equivalent to one flagger and will be measured and paid
for on an hourly basis under Item 630.1500 Flaggers. One hour of AFAD use shall be paid

(2) Use of Recycled Asphalt Materials. The Contractor may choose to use recycled asphalt
pavement (RAP) in thin lift bituminous concrete pavement mixtures. The amount of RAP
used shall not exceed 20% of the total weight of aggregate in the mixture, including the
RAP.
The use of recycled asphalt shingles (RAS) is prohibited.
Special Provisions Part II – Special Specifications
a. When any amount of RAP is used, an analysis of the RAP material, including the
extracted aggregate gradation, coarse aggregate specific gravity, fine aggregate
specific gravity, and asphalt content shall be provided in the mix design.
b. Any change in the amount or combination of recycled materials shall require a new
mix design unless otherwise approved by the Agency.
c. Should the characteristics of any proposed recycled material be such that an
acceptable mixture cannot be produced or maintained, the recycled material will
not be allowed for use on the Contract.
(3) Thin Overlay Mixture Design Process. AASHTO R 35 will be the method used to develop
a mix that will meet the specified design criteria in accordance with AASHTO M 323, unless
otherwise noted.
The mixture shall be designed using the following methodology:
a. Select materials (aggregate, asphalt binder, additives).
b. Select design aggregate structure.
c. Select design asphalt binder content.
d. Select additives content.
e. Evaluate mixture moisture sensitivity and rutting susceptibility using the Hamburg
wheel tracker test (HWTT).
f. Determine mixture cracking tolerance index (CT-Index) using the indirect tensile
cracking test.
g. Evaluate the anti-strip additive and mixture compatibility using ASTM D3625.
(4) Thin Overlay Job Mix Formula. The JMF for each mixture shall contain all of the following
information:
a. A single percentage of aggregate passing each sieve identified in Table 406-
0004.02A.
b. When applicable, a single percentage of RAP in the mixture.
c. A single percentage of asphalt binder to be added to the aggregate.
Special Provisions Part II – Special Specifications
d. A single percentage for every additive in the mixture. Each additive shall be
identified by name and purpose (e.g. anti-strip, WMA technology).
e. A single percentage for air voids.
f. A single percentage for voids in mineral aggregate.
g. The values of Ninitial, Ndesign, and Nmax.
h. The mixing temperature.
i. The design compaction temperature.
(5) Control Limits. Each mix design shall establish an upper and lower control limit (as
applicable) for every JMF parameter to determine when action should be taken or production
should be suspended.
406-0004.03 AGENCY MATERIAL EVALUATION. Thin overlay mixtures will be sampled and tested
on a statistically random basis for evaluation in accordance with the specified requirements and the
material quality will be evaluated based on the results of these tests to determine a mixture pay adjustment
from air voids and asphalt binder content. The PWL based quality determination used to establish the pay
adjustment will not be used for acceptance or rejection, which shall be based on visual inspection or
verification sampling as described below.
The actual mixture produced shall not vary from the job mix formula target values by more than the
production tolerances specified in Table 406-0004.03A. For the purposes of verification sampling, the
tolerances given in Table 406-0004.03A will be considered the specification limits for an individual
sample. Continued production outside these ranges will be grounds to halt production and rescind the mix
design.
Material may be sampled at either the production facility or on the project site and may be tested at either
the production facility’s qualified lab or at the Agency’s Materials Testing and Certification Section
Central Laboratory.

1 The mixture temperatures shall not exceed 355°F.
(a) Lots and Sublots. The entire quantity of a single mix design of thin overly mixture will constitute
a lot. Sublots shall be a maximum of 500 tons. Samples will be taken once per sublot.
At the Engineer’s discretion, low production activities, defined as a daily production of 300 tons
or less, that would otherwise be evaluated as part of the lot may be excluded from the PWL lot for
the purposes of pay factor calculation.
(b) Evaluation Method. The percent within limits (PWL) method will be used to determine the quality
of the material produced based on the quality characteristics specified in Subsection 406-
0004.03(c). The LSL shall be the lower mixture tolerance and the USL shall be the upper mixture
tolerance specified in Table 406-0004.03A. Detailed documentation on the PWL method is
available in the Agency’s Bituminous Concrete Quality Manual.
(c) Quality Characteristics. The quality of the mixture will be evaluated based on the air voids and
asphalt binder content. Asphalt binder content will be measured in a calibrated ignition oven in
accordance with AASHTO T 308.
(d) Pay Factor. A composite weighted pay factor combining the PWL of each quality characteristic
will be calculated to account for the overall quality of the lot. If mix design JMF changes cause
there to be multiple lots, a separate pay factor will be calculated for each lot.
Special Provisions Part II – Special Specifications
(e) Removal of Defective Material by the Contractor. With the approval of the Engineer, the
Contractor may elect to remove any defective material and replace it with new material at no
expense to the Agency. Any such new material will be sampled, tested, and evaluated for quality.
(f) Rounding and Reporting of Values. Results from all calculations shall be rounded and reported as
follows. All pay factors will be reported to 0.0001 and all pay adjustments to 0.01. For intermediate
calculations used to obtain pay factors and pay adjustments values shall retain the maximum
available precision.
When rounding, if the first digit to the right of the number to be rounded is greater than or equal
to 5, then the number will be rounded away from zero to the next number with larger magnitude.
If the digit to the right of the number to be rounded is less than 5, then the number will remain the
same.
406-0004.04 CONTRACTOR QUALITY CONTROL. The Contractor shall be responsible for
maintaining control of the mix production process. The mix production methods and technologies
shall generally be at the Contractor’s discretion, but will be limited to proven, Agency and industry
accepted practice. Upon approval of the Engineer and at no additional cost to the Agency, the Contractor
may use innovative equipment or techniques not included in the specifications to produce or monitor the
production or placement of the mixture.
(a) Control of Mixture. The plant shall be operated so that no intentional deviations are made from
the approved job mix formul
