Evaluating Pavement: the PCI
PAVEMENT 101
18 100 – 91 = Excellent
90 – 71 = Good
70 – 51 = Fair/ At Risk
50 – 31 = Poor
30 – 0 = Failed
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.

PEI RECOMMENDATIONS
44 • Continue to update the Pavement Management System
• Develop Multi-Year Pavement Expenditure Plan
• Critical Point - Maintenance and Rehabilitation
• Focus limited funding to preserve critical assets
• Leverage limited funds with grants (Matching Funds) on Grant Eligible Streets (Arterials)
• STIP, Complete Streets, Safe Routes to Schools
• Consider additional funding sources
