1730.3 Test Methods
Test the systems as specified in subsection 1730.2 with the following modifications: a. Precondition, cure and test all material at 75±2° F. b. Perform ASTM C 579 using only plastic inserts.
1730.4 Prequalification
a. All systems intended for use under this specification must be prequalified prior to use. Manufacturers desiring to supply material for KDOT jobs must submit a written request to the Bureau Chief of Construction and Materials, with the following information for each system:
1.Name, address and telephone number of the manuf acturer. Include the name of the preferred contact person.
2.Brand name of the system.
3.Type of material.
4.Information regarding recommended usage and applica tion instructions. If HMWM primer is required for the system, include primer information regarding recommended usage and application instructions.
5.Material Safety Data Sheets.
6.One copy of a certified test report prepared by a laboratory regularly in spected by the Cement and Concrete Reference Laboratory (CCRL) of the National Institute of Standards Technology or other approved reference laboratory, showing test results complying with subsection 1730.2. 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. c. The information, test reports and field perfor mance will be reviewed by the Bureau Chief of Construction and Materials. The manufacturer will be advised as to whether or not the product is prequalified. d. The Bureau of Construction and Materials will mainta in a list of prequalified Polymer Concrete Overlay systems. Systems will remain prequa lified as long as the formulation and manufacturing processes remain unchanged, and field experience indicates that the system functions appropriately. Changes in formulation or manufacturing processes will require new prequalification testing. Failure of the system to function appropriately in the field will be cause for removal of the product from prequalified status. Products removed from prequalified status will be considered for requalification if the manuf acturer can provide evidence the cause of failure has been positively identified, and necessary formulation changes and quality control measures have been implemented to eliminate the cause. Complete prequalification testing may be required for systems that have been removed from prequalified status.
1730.5 Basis of Acceptance
Prequalification as specified in subsection 1730.4. Receipt and approval of a Type C certification as specified in DIVISION 2600. Observation at the project to verify performance.
