"Maintenance Painting of Various Bridge Projects During 2001-2002 (KHIT #42)", R. Younce, S. Palle, T. Hopwood II
ABSTRACT
The Kentucky Transportation Center (KTC) at
the University of Kentucky has performed a series of research studies
for the Kentucky Transportation Cabinet (KYTC) to monitor various experimental
bridge painting projects and conduct
investigative work focusing on new paint systems. The research study
addressed in this report “Maintenance Painting of
Various Bridge Projects During 2001-2002” Kentucky Highways Investigative
Task No: 42 were intended to address
experimental projects in fiscal years 2001 and 2002.
KTC and KYTC Project Design Team’s joint efforts in 2000 into early
2001 centered on the preparation of experimental
bridge maintenance painting special notes, preliminary field testing/development
of new experimental paint systems and
testing of proprietary and KYTC standard specification coatings. The
laboratory tests identified candidate coatings
systems that were subsequently used in the KYTC experimental bridge
maintenance painting projects conducted under
this study. Developmental work focused on total removal and some overcoating
systems.
The objectives of experimental project monitoring were to: assess the
condition of existing paint systems on bridges
prior to maintenance painting, monitor the project throughout completion,
note problems, describe problem resolution,
appraise the condition of the final product, and report observations
and/or conclusions about the project.
This report will begin with a summary of the coatings testing work
undertaken by KTC researchers and the KYTC
Project Design Team. The experimental bridge maintenance painting monitoring
work is presented for each bridge in the
appendices. The overall results/findings of this research study are
contained in the “Conclusions” section of this report.
