Review of Literature and Maintenance Practices at State Transportation Agencies

This report reviews relevant literature related to maintenance scheduling, prioritization, and methodologies. It discusses Kentucky Transportation Center’s current approach to maintenance activities.  It also reviews policies, guidance, and other published resources of state transportation agencies in Utah, Arkansas, Montana, Alabama, and Florida to understand how those agencies execute their maintenance programs.  Key findings include:

• Organization and implementation of maintenance programs vary among state agencies with respect to scheduling and executing work.
• Many agencies have specified target maintenance conditions.
• Many states inspect a random sample of facilities two or three times per year to identify what maintenance is needed. Some maintenance activities are performed at regular intervals, but many are done on an as needed basis.
