I Il LOT will be defined (as selected by the Contractor prior to the start of the LOT) as either (1) 2,000 tons [2,000 metric tons], with each LOT subdivided into four equal sublots of 500 tons [500 metric tons] each, or (2) 4,000 tons [4,000 metric tons] (as authorized by the Engineer per 334 - 5.2.1), with each LOT subdivided into four equal sublots of 1,000 tons [1 ,000 metric tons] each. Before the beginning of a LOT, the Engineer will develop a random sampling plan for each sublot and direct the Contractor on sample points, based on tonnage, for each sublot during construction. In the event a LOT is terminated per 334 - 5.4.4, the LOT size upon resuming production of the mixture will be 2000 tons until the requirements of 334 -5.2.1 are met. 334 -5.2.1 Criteria for 4,000 ton LOTs: At the completion of the Initial Production LOT, the quality of the as- produced material will be evaluated by the Engineer. Begin the option of 4,000 ton [4,000 metric tons] LOT sizes only when authorized by the Engineer based upon the Quality Control test results for the Initial Production LOT meeting the following: 1. A minimum Pay Factor of 0.90 for each asphalt quality characteristic as defined in 334 -8.2. 2. A favorable comparison with the Verification test results. Comparisons between the Quality Control and Verification test results will be based on between - laboratory precision values shown in Table 334 -5. 3. A coefficient of permeability of less than 125 x 10 "5cm /s on each roadway core as determined in accordance with FM 5 -565. Permeability criteria apply only to coarse mixes when the average density for the sublot is less than 93.00 percent of Gmm, or when an individual density value is less than 91 .00 percent of Gmm. In the event that the Initial Production LOT does not meet these criteria, limit production LOT sizes to 2,000 tons [2,000 metric tons] with 500 ton [500 metric tons] sublots until these criteria are met. 334 -5.2.2 Partial LOTs: A partial LOT is defined as a LOT size that is less than a full LOT. A partial LOT may occur due to the following: I. The completion of a given mix type or mix design on a project. 2. A LOT termination due to a 60 day or greater delay in production. (Time periods other than 60 days may be used if agreed to by both Engineer and Contractor.) 3. A LOT is terminated per 334 - 5.4.4. All partial LOTs will be evaluated based on the number of tests available, and will not be redefined. 334 -5.3 Initial Production Requirements: The Initial Production LOT of all mix designs shall be established at 2,000 tons. During this period demonstrate the capability to produce and place the mixture as specified unless waived by the Engineer in 334 - 3.2.1. If necessary, during this time, make adjustments to the mix design, as defined in 334 -3.3. �{ Any target value adjustments to the mix design will result in the LOT being terminated and I evaluated for payment purposes per 334 -8. Do not begin 4,000 ton LOT sizes until a 2,000 ton initial production LOT (for each mix design) has been successfully completed, or is waived by the Engineer. At the sole option of the Engineer, the requirement for an Initial Production LOT may be waived based on evidence of satisfactory production, placement and performance on previous projects for that particular mix. 334 -5.3.1 Plant Sampling and Testing Requirements: Obtain one random sample of mix per sublot in accordance with 334 -5.1.1 as directed by the Engineer.
