As part of Nynas wide-ranging research and development initiatives, there are several collaborations under way with both customers and research institutes. One of these is a research project with the University of Ancona in Eastern Italy.
New, advanced analysis methods to study the interaction between bitumen emulsions and mineral surfaces provide an important contribution to achieving sustainability benefits.
With our collective duty to ensure sustainable and environmentally responsible solutions, it is more important than ever that the road construction industry strives to get things right first time and build structures to last. That implies new structures, as well as maintenance interventions, must be effectively designed and the installation must truly reflect that design.
The Nynas bitumen laboratory – BitTech – plays a key role in offering the best technical solutions in close collaboration with customers. Carl Hultin explains more.
Tests have been conducted on vulnerable road sections using waste heat from district heating plants to get rid of the ice.
A new prediction tool for asphalt deformation, enabled Nynas to quantify the benefit of using polymer modified bitumen (PMB) in asphalt pavements. A reduced rutting rate means less maintenance.
A proposed new method for studying the rheology of bitumen and binders at low temperatures proves promising. Hilde Soenen explains the method’s potential.
Employing an advanced analysis method, Nynas researchers are starting to unmask the chemical structure of bitumen. Xiaohu Lu explains how TOF-SIMS is used to analyse the surface structure of bitumen.
Since 2014, Nynas has had a laboratory at the University of Antwerp. This January the equipment was augmented with a new, advanced rheometer.
