Asphalt & Bitumen Rheology Series

This webinar took place on January 17. You can watch the recording here free of charge:

In this webinar we talked about asphalt and bitumen binder rheology, focusing on industry standards with a basic introduction to viscosity, modulus, compliance and viscoelasticity.

This webinar will cover the basic principles of dynamic mechanical testing, how to measure the viscoelasticity of a material and why it is important.  Rheological measurements of modulus, viscosity, CreepCreep describes a time and temperature dependent plastic deformation under a constant force. When a constant force is applied to a rubber compound, the initial deformation obtained due to the application of the force is not fixed. The deformation will increase with time.creep compliance and recoverable compliance will be presented along with how these properties provide a better understanding of material performance.  The attendee will gain a greater understanding of the visco-elastic spectra, why it is referred to as a material's "fingerprint" and how to use this tool to predict product performance.  We will discuss and create Master Curves, Black Space diagrams and techniques to quantify data quality together with best practices of data collection.

This presentation will complement the 'Introduction to Asphalt & Bitumen Rheology' Part 1, which covered Shear Flow (shear viscosity). Part 2 will explore DSR deformation testing in cyclic oscillation mode which provides the basic foundation for understanding non-destructive rheological measurements.
