The NTPEP Evaluation Program for facilities producing geotextiles provides a comprehensive review of the production and testing of geotextiles and of the quality management system. The evaluation starts with a desktop review of the facility’s quality manual and concludes with an on-site review of the facility’s processes and their quality management system documentation.A summary of observations and findings follows. Details of any findings are highlighted in red.Product Line Summary and Production Overview (Section 1)Quality Management System Review (Section 2)Manufacturing Process Walk-through (Section 3)Inventory Review (Section 4)Traceability (Section 5 / Appendix B)Split Sampling (Section 6)QC Testing Procedures (Appendix A)Auditor Name: Joel Sprague Audit Report Number: REV 30– 2/11 Page 2 of 23 AASHTO’s National Transportation Product Evaluation Program (NTPEP) Table Audit Report of ContentsTable of ContentsSection 1: Submittal Details 6 Section 2: Quality Management System Review 7 Section 3: Manufacturing Process Walk-through 12 Section 4: Inventory Review 13 Section 5: Traceability 14 Section 6: Split Sampling 15 Section 7: Report Signature 16 Appendix A: Quality Control Tests and Procedures 17 Appendix B: Miscellaneous Documents 23Auditor Name: Joel Sprague Audit Report Number: REV 30– 2/11 Page 3 of 23 AASHTO’s National Transportation Product Evaluation Program (NTPEP) Section 1 Audit Report Submittal DetailsSection 1: Geotextile Product Line Summary and Production Line Overview Geotextile Product Listing Classification Facility Products NTPEP # Line Expires Prime Manufacturer *Lightest weight in product line – annual UV testing req’d; # Annual asphalt retention / melting point testing req’d. a) Manufacturing Plants Used to Produce Product Line: Does the company own plants at other locations that produce, or help to produce, one or more of the products within the product line under consideration?
