Modelling the Hysteresis Loops of Hot Mix Asphalt
Abstract This study presents the first attempt to use the Bouc-Wen model to model non-linear hysteresis loops of hot mix asphalt (HMA) samples tested in fatigue in controlled strain mode using a dynamic shear rheometer (DSR). A non-linear least squares optimization was used to identify the Bouc-Wen parameters. In this work, cylindrical samples (12 mm in diameter, 50 mm in height) fabricated from a HMA called dense bitumen macadam (DBM) were tested in fatigue. The outcome of this work confirmed the existence of a good agreement between modelled and experimental hysteresis loops.
