Abstract As part of the Pennsylvania Department of Transportation’s (PennDOT) airport pavement management efforts, the Bureau of Aviation (BOA) retained Applied Pavement Technology, Inc. (APTech), assisted by DY Consultants, to evaluate the condition of the pavements at 95 public-use airports and heliports and to update their existing airport pavement management system (APMS) originally implemented in 2001. The results of this project are presented in this report and can be used by the BOA and the Federal Aviation Administration (FAA) to identify, prioritize, and schedule pavement maintenance and rehabilitation actions at these airports. During this project, the conditions of the pavements were assessed using the FAA pavement condition index (PCI) methodology – the industry standard in aviation for visually assessing the condition of pavements. During a PCI evaluation, inspectors walk over the pavement and identify visible signs of deterioration. Pavement defects are characterized in terms of type of distress, severity level of distress, and amount of distress. This information is then used to develop a composite index (PCI number) that represents the overall condition of the pavement in numerical terms, ranging from 0 (failed) to 100 (excellent). The PCI number provides an overall measure of condition and an indication of the level of maintenance or rehabilitation work that will be required to maintain or repair a pavement. The individual distress information (such as cracking, rutting, and so on) provides insight into what is causing the pavement to deteriorate, which in turn can be used to select the appropriate maintenance or rehabilitation action to correct the problem. PCI data also serve as the basis for an APMS – a computerized tool used to track pavement condition, identify pavement repair needs, and develop prioritized maintenance and rehabilitation programs with associated schedules and budgets. 17.
