First, determine preliminary upper and lower acceptance limits by applying the <br /> following tolerances to the approved JMF. <br /> Aggregate Percent Non-Statistical Commercial <br /> Passing Evaluation Evaluation <br /> 1", 3/4", 1/2", and 3/8" sieves +/- 6% +/- 8% <br /> No. 4 sieve +/-6% +/- 8% <br /> No. 8 Sieve +/- 6% +/-8% ' <br /> No. 200 sieve +/- 2.0% +/- 3.0% <br /> b. Second, adjust the preliminary upper and lower acceptance limits determined <br /> from step (a) the minimum amount necessary so that none of the aggregate <br /> properties are outside the control points in Section 9-03.8(6). The resulting <br /> values will be the upper and lower acceptance limits for aggregates, as well <br /> as the USL and LSL required in Section 1-06.2(2)D2. <br /> 2. Job Mix Formula Adjustments — An adjustment to the aggregate <br /> gradation or asphalt binder content of the JMF requires Engineer's <br /> approval. Adjustments to the JMF will only be considered if the change <br /> produces material of equal or better quality and may require the <br /> development of a new mix design if the adjustment exceeds the amounts <br /> listed below. <br /> a. Aggregates — 2 percent for the aggregate passing the 11/2', 1", <br /> 3/4' 1/2" 3/8" and the No. 4 sieves, 1 percent for aggregate passing <br /> the No. 8 sieve, and 0.5 percent for the aggregate passing the <br /> No. 200 sieve. Provide the adjusted JMF within the range of the <br /> control points in Section 9-03.8(6). <br /> b. Asphalt Binder Content —The Engineer may order or approve <br /> changes to asphalt binder content. The maximum adjustment <br /> from the approved mix design for the asphalt binder content is <br /> 0.3 percent. <br /> 5-04.3(9)A Vacant <br /> 5-04.3(9)B Vacant <br /> 111 <br /> 5-04.3(9)C Mixture Acceptance— Nonstatistical Evaluation <br /> The City will evaluate the HMA mixture accepted by Nonstatistical Evaluation <br /> by dividing the HMA tonnage into lots. <br /> 5-04.3(9)C1 Mixture Nonstatistical Evaluation — Lots and Sublots <br /> A lot is represented by randomly selected samples of the same mix design <br /> being tested for acceptance.
