Abstract:

The Federal Lands Highway Division (FLHD) has actively been involved in the use of pavement preservation strategies to maintain National Park Service (NPS) roadways. This practice dates back several decades, and has increased substantially in recent years. As an example, in 2007 the agency spent around $9 million on pavement preservation; this increased to approximately $21 million in 2009 and $29 million in 2010. In late 2010 the FLHD initiated a study to develop pavement performance models for the NPS’ pavement management system (PMS) that address the application of surface treatments commonly used by FLHD. Those treatments include chip seals, slurry seals, micro-surfacing, and thin HMA overlays. This paper discusses the issues that were encountered in addressing the project’s objectives, including issues associated with data collection, modeling to predict pavement performance, and calculating the performance benefits obtained from the application of surface treatments in terms of pavement service life extensions. In the end, performance jumps and projected life extensions of single course chip seals under specific conditions were estimated. Many recommendations were also developed to improve the FLHD’s ability to monitor and model surface treatment performance.
