The bitumen laboratory in Nynäshamn

The Nynas bitumen laboratory – BitTech – plays a key role in offering the best technical solutions in close collaboration with customers. Carl Hultin explains more.

Hot roads in the winter

Tests have been conducted on vulnerable road sections using waste heat from district heating plants to get rid of the ice.

Reducing the rate of rutting

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.

Rheology rethink

A proposed new method for studying the rheology of bitumen and binders at low temperatures proves promising. Hilde Soenen explains the method’s potential.

Revealing structure

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.
