Abstract
In this paper, the effectiveness of the group method of data handling (GMDH) and the adaptive neuro-fuzzy inference system (ANFIS) methods in modelling the fracture parameters of asphalt mixtures were studied. For this aim, the models were investigated on the fracture energy and J-integral results of hot mix asphalt in terms of temperature, RAP content and fibre content. It was found that the fibres have an outstanding effect on the fracture behaviour of asphalt mixtures especially at intermediate and high temperatures and can be considered as an alternative to enhance the fracture resistance of recycled asphalt mixtures. The fracture data of asphalt mixtures can be successfully modelled by the ANFIS method with a high level of correlation. The GMDH was unable to model the J-integral results, however, it had a fair correlation with the results of fracture energy.
