PCI stands for Pavement Condition Index, which is a numerical grade between 0 and 100 that is used to indicate the general condition of roadway pavement. Originally developed by the United States Army Corps of Engineers as an airfield pavement rating system and later adapted for use in roads, PCI is a statistical measurement based on a visual survey of the number and types of distresses in a pavement. The PCI helps County staff track the service life of its road network, and in turn, prioritize roads that need to be re-paved. PCI also helps staff identify roads which could benefit from pavement maintenance treatments, like surface sealants, which help extend service life of a road and avoid the need of more extensive rehabilitation projects.
