Acceptance will be on a LOT -by -LOT basis (for each mix design) based on tests of random samples obtained within each sublot taken at a frequency of one set of samples per sublot. A roadway LOT and a plant production LOT shall be the same. Acceptance of the mixture will be based on Contractor Quality Control test results that have been verified by the Department. 334 -5.1.1 Sampling and Testing Requirements: Obtain the samples in accordance with FM 1 -T 168. Obtain samples at the plant of a sufficient quantity to be split into three smaller samples; one for Quality Control, one for Verification and one for Resolution testing; each sample at approximately 35 pounds [16 kg]. The split samples for Verification testing and Resolution testing shall be reduced in size and stored in three boxes each. The approximate size of each box must be 12" x 8" x 4 ". Label and safely store these boxes in a manner agreed upon by the Engineer for future testing. The Contractor can retain additional split samples at their option. The asphalt content of the mixture will be determined in accordance with FM 5 -563. In the event the FM 5 -563 ignition oven goes out of service during production, the Contractor may elect to use a replacement oven at another location for no more than 72 hours while the oven is being repaired. The gradation of the recovered aggregate will be determined in accordance with FM 1 -T 030. Volumetric testing will be in accordance with AASHTO T312 -04 and FM 1 -T 209. Prior to testing volumetric samples, condition the test -sized sample for one hour at the target roadway compaction temperature in a covered, shallow, flat pan. Test for roadway density in accordance with FM 1 -T 166, 334 -5.1.2 Acceptance Testing Exceptions: When the total quantity of any mix type in the Project is less than 500 tons [500 metric tons], the Engineer will accept the mix on the basis of visual inspection. The Engineer may require the Contractor to run process control tests for informational purposes, as defined in 334 -4, or may run independent verification tests to determine the acceptability of the material. Density testing for acceptance will not be performed on widening strips or shoulders with a width of 5 ft. [1.5 m] or less, open - graded friction courses, variable thickness overbuild courses, leveling courses, first lift of asphalt base course placed on subgrade, miscellaneous asphalt pavement, or any course with a specified thickness less than 1 inch [25 mm] or a specified spread rate that converts to less than 1 inch [25 mm] as described in 334-1.4. In addition, density testing for acceptance will not be performed on the following areas when they are less than 1 ,000 feet [300 m] in length: crossovers, intersections, turning lanes, acceleration lanes, deceleration lanes, or ramps. Compact these courses (with the exception of open - graded friction courses) in accordance with the rolling procedure (equipment and pattern) submitted as part of the Quality Control Plan and as approved by the Engineer. In the event that the rolling procedure deviates from the approved procedure, placement of the mix shall be stopped. The density pay factor (as defined in 334 -8.2) for LOTs where there are areas not requiring density testing for acceptance will be prorated based on a pay factor of 1 .00 for the quantity (tonnage) of material in areas not requiring density testing for acceptance and the actual pay factor for the tonnage of material in areas requiring density. 334 -5.2 LOT Sizes: LOT sizes will be either 2,000 tons [2,000 metric tons] or 4,000 tons [4,000 metric tons]. The Initial Production LOT of all mix designs used on a project shall consist of 2,000 tons [2,000 metric tons], subdivided into four equal sublots of 500 tons [500 metric tons] each. Following the Initial Production LOT, each remaining 01 March 2007 01000 -59 03- 4122.D;
