The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars
engaged in scientific and engineering research, dedicated to the furtherance of science and technology and
to their use for the general welfare. On the authority of the charter granted to it by Congress in 1863, the
Academy has a mandate that requires it to advise the federal government on scientific and technical matters.
Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy
of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and
in the selection of its members, sharing with the National Academy of Sciences the responsibility for
advising the federal government. The National Academy of Engineering also sponsors engineering programs
aimed at meeting national needs, encourages education and research, and recognizes the superior achieve-
ments of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the
services of eminent members of appropriate professions in the examination of policy matters pertaining
to the health of the public. The Institute acts under the responsibility given to the National Academy of
Sciences by its congressional charter to be an adviser to the federal government and, on its own initiative,
to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the
Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate
the broad community of science and technology with the Academy’s purposes of furthering knowledge and
advising the federal government. Functioning in accordance with general policies determined by the
Academy, the Council has become the principal operating agency of both the National Academy of
Sciences and the National Academy of Engineering in providing services to the government, the public, and
the scientific and engineering communities. The Council is administered jointly by both Academies and
the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair,
respectively, of the National Research Council.
The Transportation Research Board is one of six major divisions of the National Research Council. The
mission of the Transportation Research Board is to provide leadership in transportation innovation and
progress through research and information exchange, conducted within a setting that is objective, interdisci-
plinary, and multimodal. The Board’s varied activities annually engage about 7,000 engineers, scientists, and
other transportation researchers and practitioners from the public and private sectors and academia, all of
whom contribute their expertise in the public interest. The program is supported by state transportation
departments, federal agencies including the component administrations of the U.S. Department of Transporta-
tion, and other organizations and individuals interested in the development of transportation. www.TRB.org

ACKNOWLEDGMENTS
This work was sponsored by the Federal Highway Administration in cooperation with the American Associ-
ation of State Highway and Transportation Officials. It was conducted in the second Strategic Highway
Research Program (SHRP 2), which is administered by the Transportation Research Board of the National
Academies. The project was managed by James W. Bryant, Jr., Senior Program Officer for SHRP 2 Renewal.
The research reported on herein was performed by Applied Pavement Technology (APTech), Inc. David
Peshkin, Vice President of APTech, was the principal investigator. He was supported in the research by the fol-
lowing APTech engineers: James Krstulovich, Kelly Smith, Kurt Smith, Angela Wolters, and Katie Zimmer-
man. Also providing support were Jim Moulthrop and Cesar Alvarado of Fugro Consultants, Inc., and
consultants Gerry Eller (formerly Executive Director of the Foundation for Pavement Preservation),
Dr. R. Gary Hicks (Technical Director of the California Pavement Preservation Center), and Dean Testa
(formerly Chief Construction Engineer with the Kansas Department of Transportation).
The authors gratefully acknowledge those individuals from state departments of transportation, industry
organizations, and academia who participated in the project survey and provided important information and
documentation for this project. The time and effort that they contributed were instrumental in the successful
completion of this project.

This research report documents the state of the practice of preservation treatment on asphalt
and concrete pavements. Although the focus of the project was on treatments suitable for
application on high-volume roadways, this report also discusses current practices for low-
volume roadways. The information presented is derived from a detailed survey of trans-
portation agencies and a review of national and international literature. In addition, the
report provides a general framework for how best practices are identified. Finally, general
guidelines were developed on the application of preservation treatments on high-volume
roadways. Presented as a separate document, Guidelines for the Preservation of High-Traffic-
Volume Roadwaysconsiders traffic volume, pavement condition, work-zone requirements,
environmental conditions, and expected performance.
For several years, pavement preservation has been an important strategy to extend the life
of roadways. As transportation agencies grapple with decreased capital budgets, pavement
preservation will continue to be an important strategy. Relatively small investments for
preservation activities, if properly timed and applied, can significantly increase infrastruc-
ture life. Several transportation agencies apply preservation strategies on lower-volume
roadways; however, the application of these strategies on high-volume roadways has lagged
behind.
The application of preservation strategies to high-traffic-volume roadways presents a
complicated set of challenges. Many of the products and approaches that have been accepted
for use on lower-traffic-volume roadways have not been accepted for use on high-traffic-
volume roadways. Often, the use of a particular product or application has too great an
impact on traffic or has not been successfully applied under high-traffic conditions. The pur-
pose of this report is to provide guidance to more effectively match pavement condition and
related considerations with suitable treatments for high-traffic-volume roadways.
