Include evidence that the laboratory is inspected regularly. Test results from the AASHTO National Transpor tation Product Evaluation Program (NTPEP) for the identical system, including primer when applicable, are acceptable in lieu of a test report from an approved reference laboratory. (7) Include a Fourier Transform Infrared Spectrophoto metry (FTIR) spectrum in transmittance mode and a bulk sample of each liquid component tested. All liquid components will be “fingerprinted” using infrared spectroscopy for use in screening future verification sample s to verify that materials submitted for use are of an identical formulation as originally approved. All data w ill be maintained as confidential and used only for QA/QC purposes.
b.In addition to the written request described above, pr equalification is also dependent upon two years of satisfactory performance in the field. Proof of performance on non-KDOT projects in Kansas may be submitted to show satisfactory performance history in Kansas.
