I 1 b. Asphalt Binder Content—The Engineer may order or approve changes to 2 asphalt binder content. The maximum adjustment from the approved mix design 3 for the asphalt binder content shall be 0.3 percent 4 5 5-04.3(9)A Vacant I 6 7 5-04.3(9)B Vacant 8 9 10 5-04.3(9)C Mixture Acceptance— Nonstatistical Evaluation 1 11 HMA mixture which is accepted by Nonstatistical Evaluation will be evaluated by the 12 Contracting Agency by dividing the HMA tonnage into lots. I 13 14 5-04.3(9)C1 Mixture Nonstatistical Evaluation— Lots and Sublots 15 A lot is represented by randomly selected samples of the same mix design that will be 16 tested for acceptance. A lot is defined as the total quantity of material or work produced for 17 each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to 18 one day's production or 800 tons, whichever is less except that the final sublot will be a I 19 minimum of 400 tons and may be increased to 1200 tons. 20 21 All of the test results obtained from the acceptance samples from a given lot shall be I 22 evaluated collectively. If the Contractor requests a change to the JMF that is approved, the 23 material produced after the change will be evaluated on the basis of the new JMF for the 24 remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in 25 progress with a CPF less than 0.75, a new lot will begin at the Contractor's request after the 26 Engineer is satisfied that material conforming to the Specifications can be produced. 27 28 Sampling and testing for evaluation shall be performed on the frequency of one sample per 29 sublot. 30 I 31 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling 32 Samples for acceptance testing shall be obtained by the Contractor when ordered by the I 33 Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer 34 and in accordance with AASHTO T 168. A minimum of three samples should be taken for 35 each class of HMA placed on a project. If used in a structural application, at least one of the 36 three samples shall to be tested. 111 37 38 Sampling and testing HMA in a Structural application where quantities are less than 400 39 tons is at the discretion of the Engineer. 40 41 For HMA used in a structural application and with a total project quantity less than 800 tons 42 but more than 400 tons, a minimum of one acceptance test shall be performed. In all cases, 43 a minimum of 3 samples will be obtained at the point of acceptance, a minimum of one of 44 the three samples will be tested for conformance to the JMF: 45 46 • If the test results are found to be within specification requirements, additional testing 47 will be at the Engineer's discretion.
