Abstract: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 the timely application of appropriate treatments while the pavement is still in satisfactory condition. Although the benefits of pavement preservation are well-known, they are difficult to quantify. Several variables can affect the cost-effectiveness of the different treatments, such as pavement conditions, climate, traffic, and regional availability. Insufficient information and uncertainty regarding treatment performance under specific conditions can deter agencies from adopting a pavement preservation program. The Pavement Preservation Group (PG) Study is a long-term research effort aimed at determining the life-extending benefits of various pavement preservation treatments. Its main purpose is to serve as a guide for agencies to select appropriate treatments that meet their site-specific needs in the most cost-effective manner possible. Under this study, numerous test sections were placed in roadways in Alabama and Minnesota between 2012 and 2019, including a wide range of treatment alternatives such as crack sealing, fog seals, chip seals, micro surfacing, thin lays, cold recycling, and various treatment combinations. Untreated sections were also used as controls in each location. Data collection was performed before treatment application, after treatment completion, and periodically once the sections were in service. Between 4 and 11 years of field performance data were collected, varying depending on location.
