If you are planning a pavement survey or just curious about the process, the PCI score is one of the most important figures to understand. PCI is an abbreviation for Pavement Condition Index. Created by the Army Corp of Engineers, PCI is a number on a scale from 1-100 that is used to summarize the overall condition of a roadway segment.
The PCI score of a road segment can be used to recommend potentially viable rehabilitation methods, costs of repairs, and even to make predictions on the future condition of pavement infrastructure. This makes the task of calculating an accurate PCI score of considerable importance. But how is PCI calculated?
When the time comes to plan a pavement condition survey for your city, there are a lot of factors to keep in mind. Which software do you use? What functional classes will you survey? Do you want to include structural condition data? At IMS, one of the most common questions we are asked is how conducting a deflection test will affect the overall analysis results, and how that might impact budgeting decisions. Let’s examine that question further, using a real world example.
