I 1 Upon discharge from the mixer, ensure that the temperature of the HMA does not 2 exceed the optimum mixing temperature shown on the accepted Mix Design Report by 3 more than 25°F, or as allowed by the Engineer. When an additive is included in the 4 manufacture of HMA, do not heat the additive (at any stage of production including in 5 binder storage tanks) to a temperature higher than the maximum recommended by the 6 manufacturer of the additive. 8 5-04.3(7) Spreading and Finishing 9 The last row of the table is revised to read: 10 3/8 inch 0.25 feet 0.30 feet 11 12 5-04.3(8) Aggregate Acceptance Prior to Incorporation in HMA 13 The following new paragraph is inserted after the first paragraph: 14 15 The Contracting Agency's combined aggregate bulk specific gravity (Gsb) blend as 16 shown on the HMA Mix Design will be used for VMA calculations until the Contractor 17 submits a written request for a Gsb test. The new Gsb will be used in the VMA 18 calculations for HMA from the date the Engineer receives the written request for a Gsb 19 retest. The Contractor may request aggregate specific gravity (Gsb) testing be 20 performed by the Contracting Agency twice per project. The Gsb blend of the combined 21 stockpiles will be used to calculate voids in mineral aggregate (VMA) of any HMA 22 produced after the new Gsb is determined. 23 24 5-04.3(9)A1 Test Section — When Required, When to Stop 25 The following new row is inserted after the second row in Table 9: 26 VMA Minimum PF; of 0.95 None4 I based on the criteria in Section 5-04.3(9)642 27 28 Evaluating 5-04.3(9)A2 A2 Test Section — the HMA Mixture in a Test Section 29 In Table 9a, the test property "Gradation, Asphalt Binder, and Va" is revised to read 30 "Gradation, Asphalt Binder, VMA, and Va" 31 32 5-04.3(9)B3 Mixture Statistical Evaluation — Acceptance Testing 33 In Table 11, "Va" is revised to read "VMA and Va" 34 35 5-04.3(9)B5 Mixture Statistical Evaluation — Composite Pay Factors (CPF) 36 The following new row is inserted above the last row in Table 12: 37 Voids in Mineral Aggregate 2 AVMA) 38 39 5-04.3(9)B7 Mixture Statistical Evaluation — Retests 40 The second to last sentence is revised to read: 41 42 The sample will be tested for a complete gradation analysis, asphalt binder content, 43 VMA and Va, and the results of the retest will be used for the acceptance of the HMA 44 mixture in place of the original mixture sublot sample test results.
