摘要：	The cost for maintaining and upgrading South Carolina’s Department of Transportation (SCDOT) roadway system is costly, and deferring the timely maintenance of the infrastructure results in proportionately greater rehabilitation costs at a later date, while contributing to congestion and accident rates. In addition, deficient pavement conditions are the cause of the majority of the tort claims received by SCDOT, costing the DOT thousands of dollars each year that could be expended on maintenance and rehabilitation. Pavement preservation represents a proactive approach to maintaining the existing transportation system. The primary research objective of this study was to identify methods to improve the implementation of pavement preservation strategies on asphalt concrete roadways in South Carolina with specific attention to pavements in the Non-Federal Aid Secondary system. The results of this study led to several recommendations for SCDOT to consider that will potentially help decision makers efficiently use funds to improve the roadway network health in South Carolina and increase the number of pavement sections in good condition over time. These recommendations include: methods to easily identify pavement sections that qualify as preservation candidates and visualize the locations of these candidate sections using GIS; local level pavement evaluation system; preservation treatment selection support tool; treatment tracking methodology to support future benefit-cost ratio analysis; and training materials for SCDOT personnel.
