  • 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
  • Observations 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
