Pavement Preservation Compendium
by David R. Geiger
More than 1.75 trillion dollars has been invested in our Nation's highway system. Managing and preserving that investment is increasingly the goal of highway agencies around the country, with more and more agencies realizing the benefits of a sound pavement preservation program. Benefits range from improved pavement performance and increased safety to higher user satisfaction and reduced overall life-cycle costs. And because applying pavement preservation treatments is faster than rehabilitating or reconstructing existing pavements, pavement preservation efforts can contribute to increased mobility, improved work zone safety, and overall improved customer satisfaction.
As highway agencies establish pavement preservation programs, they face the challenge of determining the best pavement treatments to apply to roads. Treatments must be carefully selected and must be applied when the pavement is still in good condition, that is with no structural damage. Assisting agencies in applying the right treatment to the right road at the right time will mean taking research into innovative and effective system preservation technologies to a higher level, as research to date has lagged behind the demand for knowledge. To meet this challenge and increase the knowledge available to State and local agencies, FHWA is working to build partnerships among States, industry, academia, and the Transportation Research Board. FHWA is also exploring options for launching a 5-year coordinated pavement preservation research program. This coordinated effort is vital to addressing the research, technology, and development needs of our Nation's highway agencies and to ultimately better meeting the safety, efficiency, and mobility requirements of our customers.
The articles and other reference material in this Compendium describe the many facets of pavement preservation activities underway in the United States today, from California to Michigan to North Carolina. As we look forward to advancing pavement preservation research, skills, and knowledge, they provide an introduction to what our State and local partners are already accomplishing, and a roadmap to our future.
