Estado da Arte da Avaliação de Pavimentos Aeroportuários : da transição do Método ACN/PCN para ACR/PCR

Abstract

The continuous evolution of aircraft and the increasing operational demands of airports have driven the development of more accurate methodologies for evaluating the structural capacity of airport pavements. In this context, this study aimed to analyzethe evolution of airport pavement structural evaluation methods, focusing on the transition from the Aircraft Classification Number/Pavement Classification Number system to the Aircraft Classification Rating/Pavement Classification Rating system. The research was conducted through a qualitative bibliographic review based on the analysis of technical documents, standards, manuals, and scientific publications related to airport engineering. The results showed that the traditional method played a significant role in the international standardization of pavement capacity assessment; however, it presents limitations associated with its predominantly empirical approach. In contrast, the more recent methodology incorporates mechanistic-empirical concepts, material mechanical properties, and cumulative damage models, providing evaluations that are more consistent with the actual structural behavior of pavements. It is concluded that the adoption of the new methodology represents a significant advancement in airport engineering, contributing to more accurate assessments, improved maintenance planning, and more efficient airport infrastructure management.
