Experimental analysis and predictive modelling of linear viscoelastic response of asphalt mixture under dynamic shear loading

•Dynamic shear properties of asphalt mixtures are analysed and modelled.•Impacts of gradation and raw materials are examined.•Reliable test data is used to calibrate the Hirsch model in shear.•Two models are proposed for predicting phase angle of asphalt mixtures in shear.•Experimental data verifies the improved prediction accuracy of the models.
