Pavement condition index
Methodology for assessing quality of bitumen road
The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section. 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.[2] It is a statistical measure and requires manual survey of the pavement. This index was originally developed by the United States Army Corps of Engineers as an airfield pavement rating system,[3] but later modified for roadway pavements[4] and standardized by the ASTM.[4][5] The surveying processes and calculation methods have been documented and standardized by ASTM for both roads and airport pavements:
