    Abstract

    The intrinsic viscosity of the filler is a key parameter to determine the increase in viscosity of bitumen as a function of filler volume fraction. In this study, the intrinsic viscosity of bitumen containing different organo montmorillonite (Mt) nanoclay was studied by using Simha composite model. The comparison of intrinsic viscosity was made to bitumens containing different fillers. Compared with the data on the intrinsic viscosity of other mineral fillers in bitumen, organo Mt is more effective to enhance this rheological property, due to its better compatibility with bitumen and its intercalated structure formation. These data can give a clear insight into the reinforcement mechanisms of bitumen when different types of mineral filler are used to modify the bitumen.
