Verificação da relação IRI e BBI na avaliação da irregularidade longitudinal de pavimentos aeroportuários

Abstract: A irregularidade longitudinal em Pistas de Pouso e Decolagem (PPD) é frequentemente monitorada por meio do International Roughness Index (IRI), índice desenvolvido para avaliação de rodovias. Com o propósito de melhor abordar as particularidades dos pavimentos aeroportuários, foi desenvolvido um método específico para as PPD, o denominado Boeing Bump Index (BBI). Este estudo busca verificar a relação existente entre o IRI e o BBI, a partir dos parâmetros de valor médio e crítico, obtidos pelo software ProFAA, … Show more

“…Although it was developed specifically for airport pavements, the BBI has limitations in its use, such as the failure to consider cyclic, harmonic or successive events, in addition to the speed and aircraft physical characteristics. Sousa, Carneiro and Oliveira (2022) verified a weak correlation between IRI and BBI values, especially if only their average values are considered. Thus, the authors understood that the index selected for the roughness survey and its different forms of interpretation can lead to different conclusions about decision-making regarding M&R activities.…”
