...Filipe Almeida Corrêa do Nascimento, MSc; Marcelino Aurélio Vieira da Silva, DSc An efficient airport pavement management system is essential to judge current runway conditions and predict future runway conditions and support decisions. However, one of the limitations is insufficient scope...

.... The testing and validation results also yielded high accuracy in predicting the PCI and could be combined with a pavement management system to plan timely and accurate maintenance strategies. ANNs are a computational approach devised to mimic the technique in which the human brain processes data. ANNs...

For improved management of concrete airport pavements, a non-linear PCI model was developed for the homogeneous zones and tornado diagrams were used to analyse the sensitivity of the PCI according to the independent variables of the model...
