The Process The Process

Pavement Management Process

ity of Providence - Pavem

 Develop Pavement Management Database  Pavement distress identification and quantification

(Visual Inspection Only)

• Performed in 1997, 2006, 2012 (partial)

 Refine Pavement Deterioration Curves  Pavement Condition Index (PCI) calculation on a 0 ‐100 scale

ment Management

 Define Treatment Options and Costs  Develop list of candidate projects  Apply engineering and local judgment to define annual road program

 System uses Cost/Benefit Calculation to Prioritize Projects

Project Selection

ity of Providence - Pavem

 Factors Increasing Benefit  Traffic Volume  Lower Cost  Worse Condition (Lower PCI)  How Long the Repair Type is expected to last

ment Management

 Key Concepts  Repair roads before they fall into a more expensive

“treatment band”

 Fix the Roads used by the most people.

 Determine Funding Level

Next Steps

ity of Providence - Pavem

 Utilize GIS to Coordinate Projects Geographically  Reduce Mobilization cost for contractors  “Neighborhood” Planning  Coordinate with Utility Companies

ment Management

 Perform Project Level Evaluations and Testing to

determine actual repair for each candidate street.
