25mm RAP Mix
PennDOT Beaver County is requesting quotes for a Plant Mixed asphalt product containing various percentages of
RAP material allotted in PUB 408 specifications with maximum amount of RAP less than or equal to 50%. The
material mix design must be approved prior to any delivery of materials. This material is for placement by
Department forces and equipment. The awarded vendor is to supply warm mix asphalt as approved by the District

Section 411/413 with revisions as follows:
Revise reference to 409.2(a)2/413.2(a)2 to read as follows:
Mix Containing More than 15% RAP. RAS may not be used in mixtures containing more than 15% RAP. Utilize
the class (grade) of asphalt cement in the mixture as listed in Table HR.
Furnish material conforming to the requirements of Standard Specifications for Performance-Graded Asphalt
Binder, AASHTO M 322, except as revised in Bulletin 25. Obtain material from a source listed in Bulletin 15 for the
specified grade. Provide QC testing and certification as specified in Sections 106.03(b) and 702.1(b)1.
Provide the Representative a copy of a signed Bill of Lading for bituminous material on the first day of paving and
when the batch number changes.

* Producer may elect to use either PG 64S-22 or PG 58S-28 virgin binder grade in the mix. No blending evaluation
is needed for RAP up to 30% by weight.
** A different grade of virgin asphalt may be approved if the contractor chooses to have the asphalt cement in the
RAP evaluated, and that evaluation shows that blending will achieve a 64S-22 grade at the proportions in the JMF.

Bulletin 27, Chapter 2A, 2. Department Revisions to AASHTO R35 with the following modifications:
Section 6.8 The Department will eliminate the need for three trial blends based on a Producer’s previous
Superpave mix design work with specific aggregate blends.
Section 10.1 Prepare replicate mixtures (Note 8) containing the selected design aggregate structure at each
of the following three binder contents: (1) the estimated design binder content, Pb (design); (2) 0.5 percent below Pb
(design); and (3) 0.5 percent above Pb (design).
Revise reference to 409.2(e)1.d.1/413.(e)1.d.1 to read as follows:
Apparent Moisture Content. Sample the mixture according to PTM No. 1 daily. Determine the apparent moisture
content in the mixture according to PTM No. 749. Produce a mixture with the apparent moisture content not to
exceed 0.5%. If moisture exceeds 0.5%, slow the rate of production operations and perform a subsequent PTM No.
749 test.
Revise reference to Section 409.2(e)1.e/413.2(e)1.e Corrective Action, add a fifth bullet point to read as
follows:
• QC test results on multiple specimens are < 1.5% total air voids
Mixture acceptance will be by certification.
Vendor will bid on providing estimated tonnage of 25mm Binder mix to section 20 of Beaver County. The vendor will
bid price per ton. Quantities for pick-up and delivery appear as follows:
Item 1:
Item 2:
Item 3:
tons 2500 Department Force Pick-up
tons 250 Vendor Delivery of Asphalt
tons 250 Vendor Delivery of Asphalt and Millings Hauling
Item 3 will require the vendor’s trucking to delivery asphalt and then line up to have the truck filled with millings.
Those millings will be returned to the plant and be credited toward the amount of awarded millings the vendor is to
receive.
All quantities are estimated.
Measurement and payment will be in accordance with Pub 408 Section 409.4/413.4 (Ton).
