I 1 I2 5-04.3(9)C1 Mixture Nonstatistical Evaluation — Lots and Sublots 3 A lot is represented by randomly selected samples of the same mix design that will be 4 tested for acceptance. A lot is defined as the total quantity of material or work produced I5 for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 6 equal to one day's production or 800 tons, whichever is less except that the final sublot 7 will be a minimum of 400 tons and may be increased to 1200 tons. I8 9 All of the test results obtained from the acceptance samples from a given lot shall be 10 evaluated collectively. If the Contractor requests a change to the JMF that is approved, I 11 the material produced after the change will be evaluated on the basis of the new JMF for 12 the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot 13 in progress with a CPF less than 0.75, a new lot will begin at the Contractor's request I 14 after the Engineer is satisfied that material conforming to the Specifications can be 15 produced. 16 I17 Sampling and testing for evaluation shall be performed on the frequency of one sample 18 per sublot. 19 I20 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling 21 Samples for acceptance testing shall be obtained by the Contractor when ordered by the I 22 Engineer. The Contractor shall sample the HMA mixture in the presence of the Engineer 23 and in accordance with AASHTO T 168. A minimum of three samples should be taken 24 for each class of HMA placed on a project. If used in a structural application, at least one I 25 of the three samples shall to be tested. 26 27 Sampling and testing HMA in a Structural application where quantities are less than 400 I 28 tons is at the discretion of the Engineer. 29 30 For HMA used in a structural application and with a total project quantity less than 800 I 31 tons but more than 400 tons, a minimum of one acceptance test shall be performed. In 32 all cases, a minimum of 3 samples will be obtained at the point of acceptance, a 33 minimum of one of the three samples will be tested for conformance to the JMF: I 34 35 • If the test results are found to be within specification requirements, additional 36 testing will be at the Engineer's discretion. 37 • If test results are found not to be within specification requirements, additional 38 testing of the remaining samples to determine a Composite Pay Factor (CPF) shall 39 be performed. I40 41 5-04.3(9)C3 Mixture Nonstatistical Evaluation —Acceptance Testing I 42 43 Testing of HMA for compliance of Va will at the option of the Contracting Agency. If tested, compliance of Va will use WSDOT SOP 731. 44 I 45 Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 46 308.
