Pavement Condition Index (PCI)
What is PCI?
Pavement Condition Index, or PCI, is a numerical index between 0 and 100, which is used to indicate the condition of a specific section of road pavement. Note that PCI does not apply to dirt and gravel roads.
Pavement Inspections
PCI is determined by a manual inspection process, done on site by professional pavement inspectors. Inspectors score a section of roadway by conducting a detailed examination of pavement features such as cracking and potholes.
