Description
Summary:The Superpave binder specification characterizes asphalt binders using dynamic mechanical analysis based on the principles of linear viscoelasticity. Dynamic mechanical analysis of crumb rubber modified binders showed that the time-temperature superposition principle is applicable to the crumb rubber modified binders included in this study and the master curves for these binders can be analytically represented using various techniques applicable to unmodified binders. It was observed that the unmodified and crumb rubber modified binders with the same high temperature performance grading show different viscoelastic behavior over a range of frequencies.
