The Airport Pavement Condition Index (PCI) is important in developing a runway maintenance strategy, which is carried out on the entire surface using the ASTM D5340 method. However, a significant amount of time, money, and comprehensive observation is needed for the management of hundreds of airports, especially the middle of runway, which measures 18m with numerous aircraft wheels. Therefore, this research examined PCI in the lateral wander area and modeled the relationship with standard PCI values. The ASTM D5340 guidelines with two scenarios were used to analyze the overall runway pavement survey. In scenario 1 PCI was calculated on the entire runway surface, while in scenario 2 PCI it was evaluated only on the lateral wander area. The analysis results showed that the PCI value in Scenario 2 is 23.8% (PKY) to 49.7% (TJQ) lower than in Scenario 1 because the analyzed area comprised of aircraft wheels and the environment (heat, rain). This research succeeded in developing a model of the relationship between PCIoverall as a function of PCIlateral wander, which requires development by increasing the number of runway samples. However, using PCI calculations for the lateral wander area has the potential to improve flight safety and decrease the monitoring costs for airport pavement.
