“Definition”Pavement preservation is a program employing a network level, long-term strategy that enhances pavement performance by using an integrated, cost-effective set of practices that extend pavement life, improve safety and meet motorist expectations.

Resistance
![Page 21: The FHWA Pavement Preservation Technical Appraisal Project](https://reader034.vdocuments.us/reader034/viewer/2022052411/5567f1d6d8b42aaf768b4a33/html5/thumbnails/21.jpg)
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.”
![Page 22: The FHWA Pavement Preservation Technical Appraisal Project](https://reader034.vdocuments.us/reader034/viewer/2022052411/5567f1d6d8b42aaf768b4a33/html5/thumbnails/22.jpg)
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.”

Quality Contractors
![Page 28: The FHWA Pavement Preservation Technical Appraisal Project](https://reader034.vdocuments.us/reader034/viewer/2022052411/5567f1d6d8b42aaf768b4a33/html5/thumbnails/28.jpg)
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

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
