CONDITION
INDEX (PCI)
Developed by the U. S. Army Corp of Engineers during World War II and standardized by ASTM, the PCI is an objective and rational basis for determining pavement condition and establishing maintenance priorities.
PCI = 100
PCI = 28

POTHOLES & MAINTENANCE
Potholes –
How do they form?
How do we fix?
Temporary and permanent treatment options?
- Maintenance Activities
- Crack Sealing
- Skin Patching (hot)
- Cold Patch
- Crew of 5
- 500 TONS of placed AC 100 Tons per person!
- New Pothole Truck
- New Emulsion Tank
- Purchasing a Paver & Grinder for Streets Maintenance Crews - Fleet staff completed an overhaul of Crack Sealer
HOW DO WE DECIDE
Major Factors to help us decide what Roads?
- Safety, PCI, and Traffic Volumes. Highest impact to driver - Collaboration between Operations (Ops) & Engineering
- What Streets are taking the most time for Ops to maintain - ADA requirements
- Drainage Issues – Such as Miller
- City Ops Crews on Lower traffic streets
- Approximately 14% of Arterial & Collector Roadway will be treated this year
