EXPERIMENTAL MAINTENANCE PAINTING ON VARIOUS BRIDGE PAINTING PROJECTS. KENTUCKY HIGHWAY INVESTIGATIVE TASK NO. 31

This research study monitored various experimental bridge painting projects completed through the FY 1997 and FY 1998 painting seasons (April 1 through November 15). The objectives of the research study were to: assess the condition of the existing paint on the bridge prior to maintenance painting; monitor the project throughout completion; note problems and their resolution; assess the condition of the final product; and report on observations of the experimental projects. The various experimental features incorporated into the specification are: 1) use of proprietary and Kentucky Standard Specification coatings systems; 2) new mechanical surface preparation techniques incorporating vacuum-shrouded tools and visual inspection standards; 3) higher washing pressures (than past projects) and the use of spinner pressure washing nozzles; 4) collection of paint debris during washing and cleaning operations along with procedures for handling and disposing of industrial and hazardous wastes; 5) use of full prime coat applications in lieu of spot priming; and 6) quality control/quality assurance provisions. Field monitoring during the maintenance painting of these bridges focused on inspection to: 1) determine training needs; 2) assess quality of inspection; 3) identify inspection elements requiring improvement; and 4) provide recommendations for specific steps to improve inspection. Researchers also monitored the contractors' processing of hazardous wastes.
