| Abstract: |
The Virginia Department of Transportation (VDOT) spends millions of dollars annually on bridge maintenance statewide, with bridge coating maintenance accounting for a relatively large percentage of this cost. This project will evaluate the use of a laser ablation coating removal (LACR) system on VDOT bridge components in a real world environment. The evaluation will determine if the LACR method: (1) permits VDOT to eliminate the need for certain current practices which impede efficiency and increase cost; and (2) provides any additional improvements when used on steel bridge elements. This project will include on-site and off-site components, both conducted in a field environment. The off-site testing will include employing the LACR system on bridge structure sections, environmental health-safety monitoring, and technical analysis. The on-site testing will be conducted on a VDOT bridge for the effectiveness of LACR, environmental-health safety concerns, and effectiveness (adhesion) of re-painted coatings. |
