Design and Implementation of an Airport Pavement Management System (A-PMS) Based on PCI and Heat Mapping: A Case Study of Ramp ۱ Apron at Mehrabad Airport

Airport pavements, particularly apron areas, are exposed to heavy cyclic aircraft loading, fuel and oil contamination, and continuous movement of ground support equipment. Effective maintenance and rehabilitation management of these pavements requires a data-driven decision-support system capable of accurately assessing pavement condition and translating technical findings into executable maintenance decisions. This study presents a framework for an Airport Pavement Management System (A-PMS) based on the Pavement Condition Index (PCI) and spatial heat-map analysis. The proposed method consists of five main modules: asset inventory, field data collection, pavement condition assessment, spatial visualization, and maintenance decision-making. In this framework, the apron is divided into a grid of concrete slabs, each assigned a unique matrix-based identification code, and the PCI is calculated for each slab. The results are then visualized in the form of a PCI heat map, enabling the identification of critical pavement zones and supporting maintenance prioritization. The system was implemented on Ramp ۱ apron at Mehrabad Airport, covering approximately ۲۲,۵۰۰ m² and consisting of about ۷۴۰ concrete slabs. The results indicate that integrating PCI heat mapping with matrix-based slab identification improves the interpretation of pavement distress patterns and facilitates the development of maintenance work packages. The proposed framework can also be extended to other airport pavement facilities, including taxiways and runways.
