1 1 Test Methods 2 Test in accordance with the requirements stated in the Requirements subsection. I 3 4 Prequalifications 5 a. Each anti-graffiti coating intended for use under this specification must be I 6 prequalified before use. Submit a written request for prequalification to the Bureau 7 Chief of Construction and Materials. Provide the following documentation: 8 I 9 1. Name, address, and telephone number of the manufacturer. Include the name 10 and e-mail address of the preferred contact person 11 I 12 2. Brand name of the anti-graffiti coating. 13 14 3. A complete description, literature, and set of instructions for removal of graffiti. 15 I16 4. Material Safety Data Sheets. 17 18 5. A copy of test results performed as outlined in subsection b. of 9-08.9(2) from 111 19 a recognized laboratory. Include evidence that the laboratory is regularly 20 inspected. A recognized laboratory is one operated by any State 21 Transportation Agency, the Federal Highway Administration, or any cement ' 22 and concrete laboratory regularly inspected by the Cement & Concrete 23 Reference Laboratory (CCRL) or the National Institute of Standards and 24 Technology. Test results are to be no more than 24 months out of date. I 25 26 6. An infrared spectrum of the anti-graffiti coating which was used in the 27 laboratory tests. I 28 b. Submit a one gallon sample from production to the Engineer of Tests. All coatings 29 will be fingerprinted using infrared spectroscopy for use in screening future 30 verification samples to verify that materials submitted for use are of an identical 31 formulation as originally approved. I32 33 c. The information, test reports and test results obtained at the Materials and 34 Research Center on samples submitted, will be reviewed by the Contracting I 35 Agency. The manufacturer will be advised of the results. 36 37 d. The Contracting Agency will maintain a list of prequalified products. Products that 38 have been prequalified will remain prequalified as long as the formulation and 39 manufacturing processes remain unchanged, and field experience indicates that 40 the anti-graffiti coating functions appropriately. Changes in formulation or I 41 manufacturing processes will require new prequalification testing. 42 43 Failure of the material to function appropriately in the field will be cause for removal of the I 44 product from prequalified status. Products removed from prequalified status will be considered 45 for requalification if the manufacturer can provide evidence that the cause of failure has been 46 positively identified, and necessary formulation changes and/or quality control measures have 47 been implemented to prevent future failures. Complete prequalification testing may be I 48 required for products that have been removed from prequalified status. 49 50 6-02.3.GR6 I 51 Construction Requirements 52 I MAPLE HEIGHTS BRIDGE SEISMIC RETROFIT PAGE 87 OF 106 SPECIAL PROVISIONS—Addendum 1 I WORK ORDER#3693 MAY 4,2020 FEDERAL AID#BHM-2776(008)
