The pavement preservation philosophy has seen increased adoption in State Departments of
Transportation (DOTs) across the United States as a result of the successful educational and outreach
programs instituted by FHWA and other pavement preservation organizations over the past decade.
The fact remains that the effectiveness of pavement preservation activities has not been well
documented or publicized throughout the United States. Intuitively for pavement professionals the
philosophy makes perfect sense, however, hard facts supporting this stance are still elusive except
for anecdotal examples.
The objective of this study was to conduct a synthesis to highlight the degree to which pavement
preservation treatments (including minor rehabilitation treatments) extend the service life of
pavements with or without adding strength. This study was carried out by conducting a study of six
target states that were known to perform, collectively, the totality of all treatments under
consideration.
