Acceptance of subsequent mixture lots will be evaluated on the basis of the changed JMF. 11 12 5-04.3(9)62 Mixture Statistical Evaluation —Sampling 13 Comply with Section 1-06.2(1). 14 15 Samples of HMA mixture which is accepted by Statistical Evaluation 16 will be randomly selected from within each sublot, with one sample 17 per sublot. The Engineer will determine the random sample location 18 using WSDOT Test Method T 716. The Contractor shall obtain the I19 sample when ordered by the Engineer. The Contractor shall sample 20 the HMA mixture in the presence of the Engineer and in accordance 21 with FOP for WAQTC T 168.
