Contractor Tests not Verified. If the Department VA test does not verify the accompanying Contractor tests within the verification tolerances, then the Monitoring Team will investigate. If the deviation between the District and Contractor test is greater than the limits in Table 403.06-3 immediately cease production until resolved. If the deviation is less than the limits in Table 403.06-3 and discrepancies continue, perform additional tests to aid in problem solving. TABLE 403.06-3 DEVIATION LIMITS Property Mix Limits Asphalt Binder Content All ± 0.5 % No. 4 (4.75 mm) sieve All, except 302 302 ± 6.0% ± 7.0% Additional tests may include any testing necessary to resolve the problem. If the additional testing does not resolve the problem by one-half production day or 1000 tons (1000 metric tons), whichever occurs first, to the Monitoring Team’s satisfaction, stop production, if not already, until problems are resolved. Contact the Laboratory for assistance in resolving problems. If the District testing program is confirmed by the additional tests and Monitoring Team investigation and no reason to question the original test exists, then the original District VA tests will stand. After the above investigation, one of the three following actions will occur: 1. Mix Production Compares Well to the JMF. If the District test and investigation shows mix is actually controlled well compared to the JMF in spite of the Contractor test, the District does not have to test additional samples if the Contractor testing problem is corrected. 2. Mix Production Does Not Compare Well to the JMF. If the District tests and investigation shows lack of Contractor mix control compared to the JMF the District will test the remaining Department split samples for the days or Lots represented by the original tests. The District will use the test results to calculate
195 403.07 the acceptance. While working with the District, immediately take steps to correct the problem according to the QCP. Failure to achieve a quick resolution will result in a change to Unconditional Acceptance. 3. District Testing Problem. If the District testing program has a problem as confirmed by the additional testing and District review, the District will correct the problem, throw out the original District test results and take new samples from the samples representing the days or Lots in question for the VA tests. F. Contractor Removal, Restoration. If repeated problems with poor comparison of tests are not the District’s fault; or poor comparison of Contractor tests to the JMF; or with plant operation, input materials, or any of the other requirements of Department specifications occur in a single project or successive projects, the District will request an opinion from the QCQC before notifying the Contractor of removal from Department VA. The District will immediately notify the Contractor of the removal with a follow up letter from the District Engineer of Tests. Once notified, acceptance of asphalt mixtures is by Unconditional Acceptance. Restoration of the VA procedures may occur on a future project with a District recommendation to the QCQC based on consistent improved plant operation and mix control, a review of the Contractor problems and resolutions, and a review of the QCP by the QCQC. 403.07 Unconditional Acceptance. If the Contractor is removed from Department VA, the following will occur. The Contractor must bring its QCP and operation to a level acceptable to the District and QCQC before production continues. The DET will ensure that the project C-95 (Contractor’s Prequalification Rating survey) will reflect the change to Unconditional Acceptance in all of the appropriate C-95 categories. The Department will accept all material for Department projects from the facility under Unconditional Acceptance. While the facility is under Unconditional Acceptance, acceptance of small quantities under the small quantities policy will not apply. Quality control testing requirements specified in 403.05 are modified as follows: A. The required number of test series is a minimum of four each per production day or night. If a production day is less than 6 hours, the Department may reduce the frequency but not less than one test series per every 3 production hours. B. For Basic mixes, if the variation from the JMF for one test is ±8 percent passing the No. 4 (4.75 mm) sieve or ±0.3 percent asphalt binder content, investigate and correct the problem, then resample and test. Maintain the moving average of three tests within ±4 percent passing the No. 4 (4.75 mm) sieve and ±0.2 percent asphalt binder content. In addition to the Quality Control Report, maintain control charts according to 441.10 for asphalt binder content and the No. 4 (4.75 mm) sieve. If the Range difference in any three consecutive tests is greater than 0.6 percent for asphalt binder content or 10.0 percent passing the No. 4 (4.75 mm) sieve, notify the Monitoring Team. If Range deviations as specified continue, cease production.
