A lot is defined as the total quantity of material or work produced 2 <br />for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be 3 <br />equal to one day’s production or 800 tons, whichever is less except that the final sublot 4 <br />will be a minimum of 400 tons and may be increased to 1200 tons. 5 <br /> 6 <br />All of the test results obtained from the acceptance samples from a given lot shall be 7 <br />evaluated collectively. If the Contractor requests a change to the JMF that is approved, 8 <br />the material produced after the change will be evaluated on the basis of the new JMF for 9 <br />the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot 10 <br />in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request 11 <br />after the Engineer is satisfied that material conforming to the Specifications can be 12 <br />produced. 13 <br /> 14 <br />Sampling and testing for evaluation shall be performed on the frequency of one sample 15 <br />per sublot. 16 <br /> 17 <br />5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling 18 <br />Samples for acceptance testing shall be obtained by the Contractor when ordered by the 19 <br />Engineer.

If used in a structural application, at least one 22 <br />of the three samples shall be tested. 23 <br /> 24 <br />Sampling and testing HMA in a structural application where quantities are less than 400 25 <br />tons is at the discretion of the Engineer. 26 <br /> 27 <br />For HMA used in a structural application and with a total project quantity less than 800 28 <br />tons but more than 400 tons, a minimum of one acceptance test shall be performed.
