Quality Control split sample for gradation, asphalt binder content and volumetrics in accordance with 334- 5 . 1 . 1 . Complete all Quality Control testing within one working day from the time the samples were obtained . 334-5 .4 .3 Roadway Sampling and Testing Requirements : Obtain five 6 inch diameter roadway cores within 24 hours of placement at random locations as directed by the Engineer within each sublot. Test these Quality Control samples for density (Gmb) in accordance with 334- 5 . 1 . 1 . In situations where it is impractical to cut five cores per sublot, obtain a minimum of three cores per sublot at random locations as identified by the Engineer. Do not obtain cores any closer than 12 inches from an unsupported edge . Maintain traffic during the coring operation ; core the roadway, patch the core holes (within three days of coring) ; and trim the cores to the proper thickness prior to density testing . Density for the sublot shall be based on the average value for the cores cut from the sublot with the target density being the maximum specific gravity (Gmm) of the sublot. Once the average density of a sublot has been determined, do not retest the samples unless approved by the Engineer. Ensure proper handling and storage of all cores until the LOT in question has been accepted. 334-5 .4.4 Individual Test Tolerances for Quality Control Testing : Terminate the LOT if any of the following Quality Control failures occur : 1 ) An individual test result of a sublot for air voids does not meet the requirements of Table 334 - 5 , 2) The average sublot density for coarse mixes does not meet the requirements of Table 334- 5 , 3 ) Two consecutive test results for gradation (P .200) do not meet the requirements of Table 334 - 5 , 4) Two consecutive test results for asphalt binder content do not meet the requirements of Table 334 - 5 , 5 ) The average sublot density for two consecutive sublots for fine mixes does not meet the requirements of Table 334- 5 , 6) Two core densities for coarse mixes within a sublot are less than 91 . 00% of Gmm . When a LOT is terminated due to a QC failure , stop production of the mixture until the problem is resolved to the satisfaction of the Quality Control Manager(s) and/or Asphalt Plant Level II technician(s) responsible for the decision to resume production after a quality control failure, as identified in 105 - 8 . 6 . 4 . In the event that it can be demonstrated that the problem can immediately be or already has been resolved, it will not be necessary to stop production . When a LOT is terminated, make all necessary changes to correct the problem. Do not resume production until appropriate corrections have been made . Inform the Engineer of the problem and corrections made to correct the problem . After resuming production, sample and test the material to verify that the changes have corrected the problem. Summarize this information and provide it to the Engineer prior to the end of the work shift when production resumes . In the event that a Quality Control failure is not addressed as defined above, the Engineer ' s approval will be required prior to resuming production after any future Quality Control failures . - 91 - FPID ( S ) : 423186 - 1 - 58 - 01 r.,
