MnROAD/NCAT Joint Study - National Partnership to Determine the Life Extending Benefit Curves of Pavement Preservation

Summary:

State and local agencies often face the challenge of managing their pavement networks with limited resources. The natural degradation of new pavements, influenced by traffic loads and environmental factors, necessitates attention. Extending the service life of pavements without resorting to costly rehabilitation or reconstruction activities is feasible through timely application of appropriate treatments while the pavement is still in satisfactory condition. Several variables can affect the cost-effectiveness of the different treatments, such as pavement condition, climate, traffic, and regional availability. Insufficient information and uncertainty regarding treatment performance under specific conditions can deter agencies from adopting a pavement preservation program. To address this gap, the National Center for Asphalt Technology (NCAT) and the Minnesota DOT Road Research Facility (MnROAD) partnered to study the long-term performance of multiple pavement preservation treatments, aiming to determine their life-extending benefits. The results of this study can serve as a guide for agencies to select appropriate treatments that meet their site-specific needs in the most cost-effective manner possible. The most significant outcome of this research is the development of data-driven, easily accessible resources, laying the path for future program implementations.
