Degradation-Grafting Mechanochemical Treatment of Recycled Polypropylene as an Asphalt Modifier: Rheological Behavior and Microscopic Mechanisms

As a common solid waste, recycled polypropylene (RPP) has been demonstrated to be a viable asphalt modifier for enhancing pavement performance. However, its direct application still faces bottlenecks including high processing temperatures, poor dispersion, and unstable performanc...
