An important feature of the pavement management system (PMS) is the ability to accurately determine the condition of the pavement network. The pavement distress condition rating procedure utilized by Mandli follows the Pavement Condition Index (PCI) developed by the U.S. Army Corps of Engineers. The use of PCI on road networks is an accepted method used nation wide and has been formally adopted as a standard procedure by many transportation agencies. The PCI for roads has been published as an ASTM standard, D6433.
Calculation of the PCI is based on the results of a visual condition survey in which the distress type, severity, and quantity are identified. The distress data provides insight into the causes of distress whether it is related to load or climate. To determine the condition rating using the PCI method, the pavement is divided into inspection units, which are referred to as “sample units”.
