Literature Review of Current Practices in Dealing with Fluctuations of Maintenance Budgets

A literature review was conducted to investigate current budget cutting strategies used in routine roadway maintenance planning, including methods and techniques that are employed by other state and international transportation organizations. Methods that quantify impact and increased risk factors from the reduction of routine maintenance activities were investigated. Methods developed based upon previous research were tabulated and evaluated by objective criteria such as cost savings, resource savings, and road user/stakeholder satisfaction. The researchers reviewed the data and identified the most effective risk analysis techniques, which served as the basis for the maintenance risk modeling under this project.
