Improving asphalt road pavement with nano-engineered particles

Posted On: 07/02/21

Warm mix asphalt (WMA) is gaining attention in the asphalt industry as an eco-friendly and sustainable technology. However, high moisture susceptibility and aging of asphalt make WMA less durable on the roads. To address both issues in WMA technology, a team from the Energy Safety Research Institute (ESRI) at Swansea University and Braunschweig Pavement Engineering Center (ISBS) at the Technical University of Braunschweig have discovered potential for fumed silica nanoparticles (FSNs) to be used as an anti-aging binder that can not only serve to reduce temperature but also significantly overcome limitations caused by moisture susceptibility.
