RAP Mix Design Specification

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 Materials Manager. Testing and development of mix designs will be the responsibility of the vendor and subject to review/approval of the District Materials Manager.

SUPERPAVE ASPHALT MIXTURE DESIGN, BASE COURSE, MODIFIED HIGH RAP REQUIREMENTS,

PG 64S-22, < 0.3 MILLION ESALS, 25 MM MIX-HIGH RAP

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.

Design mixes in accordance with Section 411/413 with the following modifications:

* 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: tons 2500 Department Force Pick-up Item 2: tons 250 Vendor Delivery of Asphalt Item 3: 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).

The department reserves the right to add and/or eliminate SR’s within the sections. Delivery of 25mm Binder mix will take place between August 1, 2026 & November 30, 2026.

This PO is subject to a 3-month (90 day) extension period following the validity end date.

All deliveries will be coordinated with the awarded vendor prior to required delivery date; expected delivery time will be within 3 calendar days after being notified by the Department. The material required delivery rate should be between 150 – 175 Tons/Hour depending on project.
