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 o...

In Michigan, pavement preservation is implemented primarily through the Michigan DOT's capital preventive maintenance (CPM) program, in which preventive maintenance treatments are used to protect existing pavement surfaces, to slow deterioration, and to correct surface deficiencies. An overall objective of the CPM program is to postpone major rehabilitation and reconstruction activities by extending the service life of pavements. Results of a study performed to calculate the benefits and costs of various preventive maintenance treatments used in the Michigan DOT's CPM program are presented. With benefit defined as the percentage increase in performance over a do-nothing or untreated pavement performance curve where data were available, benefits were calculated for preventive maintenance treatments. Benefit–cost ratios were calculated by unit cost, and permitted the compari...
