Nynas Bitumen Research at next ISAP Conference

Three technical Nynas presentations at the next ISAP conference (International Society for Asphalt Pavements).

The technical presentations based on results from Nynas bitumen research have been selected for presentation at the next ISAP conference taking place in Nagoya, Japan, August 2010. The technical sessions consist of spoken and poster presentations, which were selected from more than 500 submissions.

The Nynas papers are:

• Aging Characteristics of Polymer Modified Binders in Porous Asphalt Pavements, by Xiaohu Lu, Bengt Sandman and Per Redelius
• SBS Modified Bitumens: Does Their Morphology and Storage Stability Influence Asphalt Mix Performance? By Xiahu Lu, Hilde Soenen and Per Redelius.
• Asphalt production at reduced temperatures and the impact on asphalt performance by J. De Visscher, A. Vanelstraete, Hilde Soenen, Tine Tanghe, Per Redelius. The first two authors are from Belgian Road Research centre, Nynas partners in the project.

We are proud that Nynas research is recognized in three areas which are of importance for future paving technology. Aging is a very important area for improving durability, particularly for noise reducing asphalts. Understanding the improved performance of polymer modified binders is to understand the structure of the polymer (morphology) and how this influence performance under service conditions. The last paper is a report from the so called IWT project, which partly was funded by the Flemish organization for support of research and innovation in Flanders, and which have investigated different techniques to save energy by reducing paving temperature at asphalt laying.
