TU Wien presents at the third Eurobitume academia webinar

Europe |

‘Insights into a “Dark Matter” – new perspectives on the ageing of bituminous binders’ was the title of the interesting and informative third Eurobitume academia webinar, presented by the Technical University of Vienna (TU Wien) in Austria and lead by Associate Professor Dipl.-Ing. Dr. techn. Bernhard Hofko.

Associate Professor Hofko, supported by PhD student Dipl.-Ing. Kristina Hofer and Dipl.-Ing. Dr. techn. Johannes Mirwald from his research team, began with a short introduction about TU Wien and the Christian Doppler Laboratory for Chemo-Mechanical Analysis of Bituminous Materials.

The 35 individual participants, joined online by an entire class of students from Eurobitume Associate member organisation the University of Antwerp, then heard about ageing, ageing chemistry and the related challenges regarding recycling pavement materials, more complex binder materials and new/emerging test methods.

Participants then learned about the efficient simulation of bitumen ageing using the Viennese Binder Ageing (VBA) conditioning method and were given a review of emerging test methods.

The webinar then explored developments regarding the FTIR (Fourier Transform Infrared) spectroscopy analysis technique and experiences with a simple, efficient way to characterise the low-temperature performance of asphalt binders, using 4-mm DSR testing and simple links to BBR data.

Like the two previous Eurobitume member-only academia webinars, which were presented (at Eurobitume’s invitation) by the University of Antwerp in Belgium and TU Braunschweig in Germany, this webinar concluded with a lively discussion and Q&A session.

At the close, Eurobitume President Francisco Lucas (Repsol) and Technical Committee Chair Véronique Ducreux (ExxonMobil) thanked Associate Professor Hofko and his colleagues for their interesting and insightful presentations. They also looked ahead to the next Eurobitume academia webinar, which is scheduled to take place on 8th November with the University of Granada, in Spain
