SECTION 401

2.2.1.1 The unit bid price for hot bituminous pavement containing failing asphalt binder shall be assessed a 10% reduction
for one temperature grade below the specified high temperature grade or one temperature grade above the specified low
temperature grade. The penalty will be applied to all tonnage produced with the non-compliant binder. When the binder failure
is non-compliant by two grades or more, as described above, the Contractor shall be required to remove and replace all non-
compliant materia! at the Contractor’s expense, or at the Engineer’s discretion, may be allowed to leave the tonnage in place at
a unit price reduction of 50%.

2.2.2 Liquid binder samples shall be obtained by plant personnel in the presence of the Inspector/Technician. Samples
shall be obtained during each day’s production.

2.2.3. Producers and suppliers of asphalt binders shall comply with the requirement of AASHTO R 26. Asphalt binder
suppliers shall have a quality control plan approved by the Bureau of Materials and Research that complies with AASHTO R 26.

2.2.3.1 All suppliers of PG binder shall certify that the PG binder supplied for use on Department projects does not contain
used, recycled or re-refined oil.

2.3 Approval of Materials - Method Requirements.

2.3.1 At least five working days in advance of the date of starting operations, the Bureau of Materials & Research may
request that representative samples of all materials proposed for use be submitted for testing,

2.4 Composition of Mixtures - General.

2.4.1 Hot mix asphalt shall be composed of a mixture of aggregate, filler if required, and asphalt binder. The several
aggregate fractions shall be sized, uniformly graded, and combined in such proportions that the resulting mixture meets the
grading requirements of the job mix formula. The Contractor shall use the Volumetric Mix Desi gn Method in AASHTO Standard
Practice R 35 as moditied herein.

2.4.2 The Contractor shall have the option of utilizing asphalt pavement removed under the Contract, if any, or old asphait
pavement from an existing stockpile or supplying all new materials for the production of asphalt pavement or any combination
of the foregoing. If the job mix formula uses recycled materials, the mix shall meet the requirements of Reclaimed Asphalt
Pavement as specified in 2.9.

2.4.3 The Department allows the use of recycled binder in mix designs, up to 1.0% Total Reused Binder (TRB) without
any change in asphalt binder requirements as long as the mix design meets all volumetric mix design criteria. When a design
has been completed using the maximum allowable percentage of TRB, one point verifications may be performed using decreasing
percentages of TRB. Ifthe design is not validated using a decreased amount of TRB, a new design will be required.

2.5 Job Mix— General.

2.5.1 When a new volumetric mix design is required, the Contractor shall use the Volumetric Mix Design Method in
AASHTO Standard Practice R 35 to develop a mix that meets the associated design criteria. The Mix design shall follow the
procedure detailed in AASHTO with the following exceptions: Amend Table 1 Superpave Gyratory Compaction Effort to read
as follows:

Add the following:
Minimum Binder Content
20 Gyration 7S Gyration
5.8% 1/2” 5.5%
AM AP 4% _—
4.6% 1” 43%

This required minimum asphalt content is based on the use of aggregate with a specific gravity of 2.65 to 2.70. The minimum
asphalt content requirement may be adjusted when aggregate with a higher specific gravity is used, or the minimum may be
adjusted at the Engineer’s discretion if it is believed to be in the best interest of the Department.

preblended aggregate specimens for gyratory and 2 preblended aggregaie specimens, suitable for AASHTO T-209 when mixed
with the appropriate asphalt, in order to verify the design. M&R will accept the mix design based on the submitted information
meeting the mix requirements and on verification of the mix volumetrics of the submitted specimen. If the verification samples
indicate voids between 3.0 and 5.5 percent, and the Voids in Mineral Aggregate (VMA) and Voids Filled with Asphalt (VFA)
fall within the specified limits, then the design will be accepted. Once accepted, the approved mix design is the job mix formula
(JMF). If the voids are outside the aforementioned range or the VMA or VFA are outside the specified limits, the design will be
rejected. M&R may elect to verify the design again.

2.5.3. The proposed mix designs and materials shall be submitted to the Engineer a minimum of 20 working days before
placement for approval. It shall be the responsibility of the Contractor to ensure all approved mix designs have been entered into
the plant automation system before production begins. The Contractor will also be required to post a copy of the JMF in the DOT
testing laboratory.

3.1.1 General.

e Coarse aggregates shall be furnished in at least two nominal sizes for mix types containing top size
aggregates of 1/2” and larger.

@ RAP shall be fed into the plant by equipment specifically designed for recycling and approved by the
Bureau of Materials and Research. In addition, all requirements pertaining to aggregates shall apply to
RAP. Scalping screens, grizzlies, or similar devices shall be installed on the RAP feed bin(s) to remove
any debris or other foreign materials in excess of 2”. If a drum mix plant is used, the RAP shall be fed
into the drum so that it will not come in direct contact with the burner flame. Mixing of RAP with the
new aggregate shall occur before the bituminous material introduction point. The final mix produced
shall be visually free from any chunks of RAP.

e Plants shall be approved at least five days prior to operations and will be capable of maintaining an
adequate supply of mixture to the project.

3.1.2 Method Requirements.

e The site shall have ample storage space for the required separate bins, stalls, or stockpiles to allow
delivery of uncontaminated sized aggregates to the feeder. To prevent spillage from one pile or bin to
the next, aggregate assigned to different stockpiles shall be separated by bulkheads or other satisfactory
means.

e Stockpiles of coarse aggregate produced for use in drum mix plants having top size aggregates greater
than 3/4” shall be constructed in layers not to exceed 4 ft.
