Resistance
21
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.

22
Obstacles
23
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

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.

Observations
33
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

34
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
