    A. BASIC REQUIREMENTS

    There are two basic requirements for Producer’s facility approval. The Producer’s facility must have an approved in-house QC PGAB plan that meets the requirements of AASHTO R 26 Section 9 and must use an AASHTO re:source (formerly AMRL) approved laboratory conforming to applicable sections of AASHTO R 18. See Section II (c). References to the word “lot” in AASHTO R 26 or other specification documents and the word “batch” used by NCDOT have the same meaning and are congruous.
    B. QC PLAN

    The program requires that the Producer have a QC plan that meets the requirements of Section 9 of AASHTO R 26 (Standard Practice for Certifying Suppliers of Performance Graded Asphalt Binders). This is a comprehensive standard complete with guidelines. A Northeastern User’s Producer’s Group (NEAUPG) Model QC plan has been provided as a guide in Appendix I (website). Appendix II has Section 1020 of the NCDOT Specifications (website).
    C. APPROVED LABORATORY

    The Program requires all tests associated with the testing of asphalt binder to be conducted at an AASHTO re:source (formerly AMRL) accredited laboratory conforming to the applicable sections of AASHTO R 18 that is qualified in the following procedures in Table 1 below.  All equipment used at that laboratory is calibrated and maintained per AASHTO R 18.  For information on how to become an accredited laboratory contact AASHTO or visit their website at http://www.aashtoresource.org.

    D. PLANT APPROVAL PROCESS 
     
    The approval process requires the Producer to write the State Materials Engineer at NCDOT, 1801 Blue Ridge Road, Raleigh, NC 27607, requesting that the plant be considered for acceptance into the program.  It must identify the specific products that are to be produced. Two copies of the Producer’s written QC plan must be submitted with the request for approval.
     
    The NCDOT will review the Producer's written QC plan and if it is approved, an on-site inspection will be scheduled.  This on-site inspection will verify that the Producer's QC plan has been implemented and is being followed. If either the Producer's QC plan or laboratory does not meet NCDOT requirements, the Producer will be informed of the deficiencies in writing.  Once the deficiencies have been addressed, the Producer may again request approval in writing to the State Materials Engineer.  
    E. CERTIFICATION FOR PARTICIPATION IN THE QC/QA PROGRAM 
     
    If the NCDOT has approved the Producer’s written QC plan and the on-site inspection confirms that the initial program requirements have been met, NCDOT will certify the Producer for participation in the program.  At the end of the year, and each subsequent year, NCDOT will approve participation for the upcoming year once a letter certifying/updating the Producer’s QC plan for the coming year has been received and any necessary inspections are made.  Any time changes are made documentation in the form of a letter from the Producer shall be provided to the Materials and Tests Unit. Random inspections may be conducted at any time by NCDOT to verify compliance with the program requirements.  Failure to perform all of the program requirements may result in a Producer being removed from the Program.
    F. STATEMENT OF REMEDIATION   
     
    In the event that material not meeting specification is shipped, the NCDOT will be immediately notified and pavements (if any) constructed from the material may be rejected and removed from the site unless otherwise permitted by the Engineer in accordance with Article 105-3 of the Standard Specifications, CONFORMITY WITH PLANS AND SPECIFICATIONS.
