The Pavement Condition Index (PCI) is a numerical index between 0 and 100 which is used to indicate the condition of pavement. This index was developed by the United States Army Corps of Engineers and has been standardized by American Society for Testing and Materials (ASTM D6433 - 11: Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys).
