The Utilization of Waster Plastic as a Polymer Modifier for Asphalt Binders

Polymer-modified asphalt (PMA) has shown great promise in improving the performance of flexible asphalt pavements at low, intermediate, and high temperatures by increasing pavement resistance to permanent deformation, thermal cracking, and fatigue cracking. Recently, waste plastics (WPs) have been explored for making PMAs and incorporating them in asphalt binder through wet processes due to WP abundance and their ability to act as bonding enhancers. Nebraska Department of Transportation (NDOT) is interested in exploring the use of WP as an alternative sustainable material for binder modification. This research effort can contribute to reducing, reusing, and recycling waste plastic materials while providing enhanced binders and asphalt mixtures.
