** 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:
