Many factors affect a city’s or county’s pavement condition index, or PCI score. These include pavement age, climate and precipitation, traffic loads and available maintenance funding.
A municipality with new housing developments and new streets may have a high overall PCI, while an older, urbanized jurisdiction may have a much lower PCI, even though both are practicing pavement preservation. Cities and counties that practice preventive maintenance will have lower long-term pavement costs and will safeguard their investment in local streets and roads.
The typical stretch of Bay Area asphalt shows serious wear and likely will require rehabilitation soon. At 67 out of a possible 100 points, the region’s average pavement condition index (PCI) score is much closer to the 60-point threshold at which deterioration accelerates rapidly and the need for major rehabilitation becomes much more likely than to the 85-point score that represents a state of good repair.
MTC's updated Pothole Report: Bay Area Roads at Risk includes a table showing the average PCI scores for each Bay Area city and county at the end of 2017.
(PCI = 80-100)
|Newly constructed for resurfaced pavement with few signs of distress.|
(PCI = 70-79)
|Pavement requiring mostly preventive maintenance and showing only low levels of distress.|
(PCI = 60-69)
|Pavement at the low end of this range is significantly distressed and may require a combination of rehabilitation and preventive maintenance.|
(PCI = 50-59)
|Deteriorated pavement requiring immediate attention, including rehabilitative work.|
(PCI = 25-49)
|Pavement showing extensive distress and requiring major rehabilitation or reconstruction.|
(PCI = 0-24)
|Extremely rough pavement that needs complete reconstruction.|
