Abstract:Pavement preservation is a strategy of maintaining a pavement’s functional condition at relatively low cost. By extending pavement life and enhancing pavement performance, preservation practices provide and maintain serviceable roadways in a cost-effective manner. To help with the pavement preservation decision-making process, the South Dakota Department of Transportation (SDDOT) has a well-developed pavement preservation program with guidelines that have served as a template for other DOTs. Those guidelines, however, were last updated in 2010, and many advances in pavement preservation practices had been made in the interim. Accordingly, the overarching objective of the research detailed in this report was to update SDDOT’s pavement preservation guidelines to reflect changes in preservation practices, as well as to develop a simple cost-benefit analysis method that could be considered at the state or local level.
