Accelerated Maintenance Painting – Jefferson County Federal Aid Research Task No. 135, Sudhir Palle, Theodore Hopwood Ii
Accelerated Maintenance Painting – Jefferson County Federal Aid Research Task No. 135, Sudhir Palle, Theodore Hopwood Ii
Kentucky Transportation Center Research Report
The Kentucky Transportation Cabinet (KYTC) conducted an experimental project to investigate the use of accelerated maintenance painting on several overpass and elevated steel structures (74,000 ft2) in Louisville. Accelerated maintenance painting procedures specified for this project entailed limited access for the painting contractor coupled with incentives/disincentives to complete each phase of the work involving traffic closures on the underlying roadways. The approach was coupled with the use of abrasive blasting for surface preparation and the application of a rapid-cure 2-coat paint system to facilitate the work.
The project was let for $402,800. The contractor proceeded to paint 4 spans designated …

Evaluation Of The Service Performance Of Bridge Components, Theodore Hopwood Ii, Robert Brown
Kentucky Transportation Center Research Report
This study was initiated to provide review of common bridges to determine the performance of their components. Seven bridge types were selected that constituted 85 % of the Kentucky Transportation Cabinet (KYTC) bridge inventory. 319 bridges were inspected by Kentucky Transportation Cabinet (KTC) researchers, representing 5 about % of those bridges. Common details/components were identified and evaluated including features of interest to the KYTC Study Advisory Committee. In addition to those findings, KTC researchers evaluated KYTC National Bridge Inventory reports and maintenance needs forms for the same bridges.
Design modifications/material changes were recommended to improve performance of new bridges. Additionally, …
Maintenance And Operations Plan For Intelligent Transportation Systems In Kentucky, Jennifer R. Walton, Joseph D. Crabtree
Maintenance And Operations Plan For Intelligent Transportation Systems In Kentucky, Jennifer R. Walton, Joseph D. Crabtree
Kentucky Transportation Center Research Report
This report presents a Maintenance and Operations Plan for Intelligent Transportation Systems (ITS) in Kentucky. It was developed using substantial stakeholder input and provides recommendations and specific strategies for supporting and coordinating ITS maintenance and operations activities throughout the Kentucky Transportation Cabinet.
A literature review and national survey helped to identify other states and urban areas that had already completed work on ITS maintenance and operations. From this information, best practices were developed that represented the lessons learned and practices implemented (or suggested for implementation) by these states. Another survey was conducted to determine the current state of ITS maintenance …
