The FHWAPavement Preservation Technical Appraisal Project
What is it?
Large-Scale Process Review Interviews with key State
DOT personnel Snapshot of Pavement
Preservation Programs
What is it? Started in July 2005
Provide State Appraisal Results
Identify National Trends
Comparisons of State Results to National or Regional Trends
National Center for Pavement Preservation
Contracted with FHWA to conduct appraisals
Formed in 2003 at Michigan State University

Resistance
Resistance to Preservation
“Monetary issues have been the most prominent obstacles. When money is needed for another purpose, or when actual revenues fall short of anticipated, the preservation program is one of the easiest target.”
“Maintaining a consistent funding base for pavement preservation in the face of overwhelming needs in other important areas: capacity, safety, political projects necessary for support of bond issues, etc.”
Obstacles
Obstacles Cited
“Budget, budget and budget. In addition there will be some resistance internally to develop a pavement preservation program because we have traditionally not adopted that line of thinking.”
“Changing from a "worst-first" mentality.”
“Interdepartmental communication issues.”
Greatest Potential for Success
Greatest Potential for Failure
Project Selection
Quality Contractors
Comments on Contracting
“The agency has experienced major difficulties in attracting preservation contractors. North Region: It is very difficult finding qualified contractors.”
“Workmanship quality and contractor experience has been a problem for the District. Often the district cannot get good bid prices because only one contractor bids the work.”
“Construction and preservation work is accomplished by the same contractors, and these firms may not necessarily provide the quality work or quality control procedures needed.”
Need for Research
How Reliable is PMS?
Integrated Preservation Treatments
ObservationsObservations
Pavement Preservation
Observations A recognized need for pavement
preservation Many agencies in early stage of a
preservation program Poor experiences with some treatments Limited contractor base Limited suite of treatments in “toolbox” Great need for training and certification
Observations Lack preservation program funding Internal resistance to change Need to expand public education /
awareness Better tracking and PMS integration
needed Need for greater FHWA Division support “Worst First” project selection paradigm
