Evaluate and compare the test results from Section 4a to the 6 results from the original sequestered stockpile properties from 7 the mix design. Develop a written plan defining how the 8 RAP/RAS will be incorporated into the sequestered stockpile 9 without materially changing the binder grade or aggregate 10 gradation properties of the sequestered stockpile. Submit the 11 test results and incorporation plan to the Engineer for 12 approval. 13 14 Table 3 Test Frequency of RAP/RAS During RAP/RAS Stockpile Construction for Approving a High RAP/Any RAS Mix Design for Placement on the QPL Test Frequency1 Test for Test Method 1/1000 tons of RAP (minimum of 10 per mix design) and 1/100 tons of RAS (minimum of 10 per mix design) Asphalt Binder Content and Sieve Analysis of Fine and Coarse Aggregate FOP for AASHTO T 308 and FOP for AASHTO T 30 1/400 tons of RAS (minimum of 5 per mix design) Asbestos content <0.1% PLM Test Method EPA/600/R-93/116 (1000 Point Count) See Section 9-03.21(1)A 1/200 tons of RAS (minimum of 5 per mix design) Asbestos Containing Material (ACM) <1.0% PLM Test Method EPA/600/R-93/116 See Section 9-03.21(1)A 1“tons”, in this table, refers to tons of the reclaimed material before being incorporated into HMA. 15 5.
