Effectiveness of Pavement Preservation Techniques, TR-709

项目名称：	Effectiveness of Pavement Preservation Techniques, TR-709
摘要：	Pavement preservation has shown to improve pavement performance and the desire to maximize Iowa's infrastructure investment has led Iowa to invest in collecting pavement performance information. This data, combined with construction and contract records can provide a better understanding of the effectiveness of pavement preservation techniques on Iowa roadways. Pavement preservation research requires results that clearly demonstrate their effectiveness for enhancing a pavement's ride quality, and delaying deterioration. Pavement preservation performance extends beyond research to an overarching shift in asset management that seeks to cost-effectively delay pavement deterioration through proactively addressing pavement imperfections before a substantial decrease in serviceability. Iowa has actively used pavement preservation methods as a way to extend pavement service life on both portland cement concrete (PCC) and hot mix asphalt (HMA) pavements. Improved understanding of pavement preservation techniques for both PCC and HMA is needed with a focus on pavement performance over time, the cost-effectiveness of preservation strategies and an effectiveness index that can be used to objectively evaluate preservation strategies.
