Grants and Contracts Details


OBJECTIVES: The objectives for this project are to: 1. Detelll1ine the state ofOAP (Optically Active Pigments) technology and identify potential sources of OAP b,·idge coatings. 2. Develop a test procedure to effectively test OAP coatings under a range of lighting levels that replicate inspection circumstances along with comparative tests on conventional coatings (i.e. by inspections using light sources in the visual light spectrum). These procedures should include evaluations of common bridge coatings defects. 3. Determine the effectiveness of the OAP coatings by comparison tests in the visible light spectrum for typical KYTC coatings inspectors. 4. IfOAP coatings perfOlll1 well, seek to extend the use ofOAP/UV technology to coating applicators/contractors for use during spray-out with the intent of improving the quality of applied coatings. 5. Develop special notes for experimental maintenance painting projects using OAP coatings. 6. Conduct laboratory tests of the OAP coatings to determine whether they meet CUlTent KYTC Category 2 Maintenance Coatings requirements. 7. Document all research findings.
