17. ETF QA Protocols - Emulsion • Outcome of a QA Program for All Emulsion Treatments based on 23 CFR 637 • Materials QA: • Acceptance Testing (Agency) • QC - Quality Control (Contractor) • IA - Independent Assurance (Agency) • New Process / Product Acceptance Procedures • Materials Certification: • Agency Acceptance Plans • QC Plans (Contractor) • Vendor Supplied Material Certifications • Workmanship QA: • Equipment Calibration • Construction Process Checks

18. ETF QA Protocols – (Cont.) • Education and Training: • Define the training needs for Agency / Contactor Staff • Education and Training Resources • NHI • TCCC • Industry Sponsored Training • Certification Program for Contractor / Agency Field Staff Note: National Center for Pavement Preservation is taking the lead on education and training.

19. Pavement Preservation: Quality Assurance Essentials

20. Quality Assurance – Definition & Regulation AASHTO R10 & TRB Circular E-C 037 • Quality Assurance –All those planned and systematic actions necessary to provide confidence that a product or facility will perform satisfactorily in service … • QA Regulated through 23 CFR 637

21. Source: IBA Consultants, Inc.

22. Core Elements of a Quality Assurance Program • Establishes the core programmatic elements required to achieve quality materials and workmanship.

23. Definition Contractor Quality Control (QC) Quality Control - QC - “The system used by a Contractor to monitor, assess and adjust their production or placement processes to ensure that the final product will meet the specified level of quality.”

24. Contractor Responsibility for Quality Control QC is the responsibility of the Contractor The party producing or placing the product is in the best position to exercise Quality Control

25. Scope of Quality Control Activities • Contractor’s QC system should address: • Materials production processes • Materials transportation and handling • Field placement procedures • Calibration and maintenance of equipment • Activities (sampling, testing and inspection) to maintain each process in control • Means to make timely adjustments and corrections

26. Contractor QC Operating Documents – QC Plan QC Plan Quality Control Plan - A project specific document prepared by the contractor which identifies QC personnel and procedures that will be used to maintain production and placement processes in control and meet theagency specification requirements.

27. Agency Acceptance Program • Monitor adequacy of QA activity • Verification sampling and Testing – materials, products, and workmanship • Inspection / Monitoring of Workmanship Agency determination of the quality of the product as specified in the contract requirements.

28. Acceptance Function • The primary objectives of agency acceptance are: • MeasuretheQualityof all materials producedand placed by the contractor • Determinethe corresponding paymentthe contractor should receive • Acceptance is not focused on directing the methods used to achieve conformance

29. Independent Assurance - IA Independent Assurance- “Activities that are an unbiased and independent evaluation of all the sampling and testing procedures used in the Quality Assurance Program”

30. Independent Assurance – IA (cont.) • Performed by Agency or Designated Agent personnel who are not directly responsible for project Acceptancesampling and testing • Provides periodic independentevaluation of QC and Acceptancepersonnel and their equipment • Not used to make a determination of work quality or acceptability

31. Laboratory Accreditation Required For: Agency Central Laboratories Consultant Labs used for Independent Assurance (IA) Consultant Labs used for Dispute Resolution

32. Laboratory Qualification • Agency Laboratory Qualification Program For all other Labs performing sampling and testing that are utilized in the Agency’s acceptance decision

33. Requirement for Personnel Qualification / Certification • Formal training • On-the-job training • re-qualification intervals • Proficiency demonstration • A written exam* • A process for disqualification or decertification A complete personnel qualification/certification program should include, at minimum: *May be used for qualification

34. Materials Testing Dispute Resolution Dispute Resolution- The procedure used to resolve discrepancies between the Agency’s Acceptance and Contractor’s QC testing results that could impact payment. Dispute Resolution system required when QC results used in Acceptance decision.

35. Responsibility for Dispute Resolution Can be performed within the DOT Use of accredited third party laboratory can be used.
