Pavement condition index

The PCI is widely used in transportation civil engineering[1] and asset management, and many municipalities use it to measure the performance of their road infrastructure and their levels of service.

[4][5] The surveying processes and calculation methods have been documented and standardized by ASTM for both roads and airport pavements: The method is based on a visual survey of the number and types of distresses in a pavement.

First, the type and extent of existing distresses, their severity level is collected.

For large pavement systems, the process may involve surveying a random or representative sample of the entire system with the following steps: This condition index can give a good indication of the pavement condition of a network.

For example, two roads with the same PCI can have significantly different IRI values as a result of having different types of distresses or grades.
