Second, adjust the preliminary upper and lower acceptance limits determined 7 from step (a) the minimum amount necessary so that none of the aggregate 8 properties are outside the control points in Section 9-03.8(6). The resulting I 9 values will be the upper and lower acceptance limits for aggregates, as well as 10 the USL and LSL required in Section 1-06.2(2)D2. 11 2. Job Mix Formula Adjustments —An adjustment to the aggregate gradation or I 12 asphalt binder content of the JMF requires approval of the Engineer. Adjustments 13 to the JMF will only be considered if the change produces material of equal or 14 better quality and may require the development of a new mix design if the 15 adjustment exceeds the amounts listed below. 16 a. Aggregates —2 percent for the aggregate passing the 11/2', 1", 3/4' 1/2" 3/8" and 17 the No. 4 sieves, 1 percent for aggregate passing the No. 8 sieve, and 0.5 18 percent for the aggregate passing the No. 200 sieve. The adjusted JMF shall 19 be within the range of the control points in Section 9-03.8(6). 20 b. Asphalt Binder Content — The Engineer may order or approve changes to 21 asphalt binder content. The maximum adjustment from the approved mix 22 design for the asphalt binder content shall be 0.3 percent 23 I 24 5-04.3(9)A Vacant 25 26 5-04.3(9)B Vacant 27 28 5-04.3(9)C Mixture Acceptance — Nonstatistical Evaluation 29 HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the 30 Contracting Agency by dividing the HMA tonnage into lots. 31 1 32 5-04.3(9)C1 Mixture Nonstatistical Evaluation — Lots and Sublots 33 A lot is represented by randomly selected samples of the same mix design that will be I 34 tested for acceptance. A lot is defined as the total quantity of material or work produced 35 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 36 equal to one day's production or 800 tons, whichever is less except that the final sublot 37 will be a minimum of 400 tons and may be increased to 1200 tons. 38 I N.
