Pavement Management System
Used by Washington County for last 20 years
Goodpointe “ICON” software used to manage data
Data collection every two years
Data updated every year with new construction projects
Pavement Management Conventions
Pavement Condition Index (PCI) Index from 0 to 100 that is used to indicate the
condition of a roadwayPoor Condition — PCI of 0 to 40Fair Condition — PCI of 40 to ~66Good Condition — PCI of ~66 to 100
County Performance MeasureAverage minimum PCI of 72

What is the Problem?
Goal is to develop and adequately fund a pavement preservation program
Need to define issue and solutions
How do we do this?
What is the Problem?
Inventory Assets Location and dimensions Traffic volumes Construction and maintenance history
Pavement Management System/Asset Management ICON PathWeb GIS Spreadsheet
What is the Problem?
Assess Roadway Condition Data collection van (2-year cycle)
Field verify condition of other assets associated with roadway
Forecast Asset Condition

How Do We Solve the Problem?
“Worst First” vs. Maintain “Good” Roads
Management and Preservation vs. Reconstruction and Expansion
Recycle vs. Reconstruction
How Do We Solve the Problem?
Look at the Whole System
Balanced Investment Plan
Long-Life Rehabilitation Projects Signs, Culverts, Trails, Paint Signal Poles,
Mailboxes, etc. Safety Improvements
Use Multiple techniques

What will it Cost?
Asset value Comprehensive
Annual Financial Report (CAFR)
Used 3% of highway asset value for proposed annual pavement preservation budget
What will it Cost?
Gap analysis Initially on a 30-year overlay cycle
Recognize different types of roadway funding State Aid Wheelage Tax Property Tax/Levy Assessments (city)

How Do We Communicate the Problem?
Elected Officials
Local Units of Government
Public – Residents, Businesses, Schools
Staff
How Do We Communicate the Problem?
There is a problem Back to needs assessment
It would be irresponsible if we don’t address the problem Everybody wants smooth, safe roadways
The approach we want to use is reasonable Well thought out solutions
How Do We Communicate the Problem?
Modified Performance MeasuresAverage minimum PCI of 72No road below a PCI of 40
Pavement Condition Index (PCI)Red Zone — PCI of 0 to 40Yellow Zone — PCI of 40 to ~66Green Zone — PCI of ~66 to 100
How Do We Communicate the Problem?
How Do We Communicate the Problem?
Develop 3-Year plan; not predictable enough for 5-Year plan Helps municipalities/other agencies plan their
programs
