Northville Municipal Pavement Management System
Spalding DeDecker. (SD) provided detailed pavement evaluation and inventory of Northville’s approximately 25-mile-long roadway network. The information obtained was used to develop a Municipal Pavement Management System, complete with multiple budget scenarios and a conceptual 10-year work plan to help the City determine appropriate funding levels.
Field Investigation
- Visual inspection of pavements in accordance with the established PASER method
- Data collection of varying distresses in multiple types of pavement
- Evaluation of sidewalks, utilities, and curb & gutter to assist in future repair recommendations
Data Organization and Pavement Criteria
- Created network containing more than 170 pavement segments based on Overall Condition Index (OCI), Repair Priority, Pavement Use, and Pavement Classification.
- Developed unique deterioration curves to account for each type of pavement according to materials (asphalt, concrete, overlaid concrete) and thickness (standard or heavy duty).
Summary of Network
- Provided detailed analysis of current network conditions based on obtained information
10-Year Work Plan Results and Recommendations
- Implemented computer software analysis to provide conceptual 10-year work plan based on predicted annual expenditures
- Output included Budget Summary, Budget Surplus, and Segment Repair Recommendations Reports
- Additional analysis included Network Backlog and Work Plan Distribution
- Alternate budget scenarios provided to help determine future expenditure requirements
Pavement Life
- Typical extended service life gains for various pavement treatments
- Overview of the costs and benefits associated with various preventive maintenance, rehabilitation, and reconstruction repairs
