Improved Viscosity Model for Bitumen-Solvent Binary Mixtures

Abstract

New viscosity model named "Faisal-Viscosity model" was developed to address the large gap in the current rules and models in giving accurate predictions on the behaviour of bitumen-solvent mixtures. The Faisal's developed viscosity model is successfully able to give a more accurate prediction for bitumen solvent mixtures compared to the Ried model with a maximum relative error of 57% while Ried's equation has a maximum error of 1931%.
