Effect of colloidal structure of bituminous binder blends on linear viscoelastic behaviour of mixtures containing Reclaimed Asphalt Pavement

摘要

Hypotheses: The influence of binder properties on rheological behaviour of mixtures (produced with different contents of Reclaimed Asphalt Pavement and base binders) was investigated. Bitumen is responsible of the viscoelastic nature of mixture behaviour. Therefore, if mechanical properties of bituminous binders depend on their chemical composition and colloidal structure, then proportions of colloidal fractions of binders are expected to be related to linear viscoelastic modelling of mixtures.
