Project Overview<\/strong><\/h4>\n
\n

This research highlights the dual challenges of infrastructure performance and environmental sustainability associated with Canada\u2019s extensive asphalt road network. With over one million kilometers of roadway and asphalt as the dominant pavement type, binder quality plays a critical role in pavement durability. At the same time, millions of tons of plastic garbage are produced every year, the most of which is dumped in landfills, which raises serious environmental concerns.<\/p>\n

\n

To address these issues, the study focuses on developing sustainable asphalt binders through the incorporation of waste plastic materials. Three commonly available plastics such as HDPE, PP, and PET are used as modifiers at varying contents to improve binder performance. A multiscale experimental approach is adopted, combining chemical, microstructural, and surface energy analyses to better understand the influence of plastic additives on asphalt behavior.<\/p>\n

The research employs advanced characterization techniques to evaluate performance enhancement mechanisms. FTIR analysis is used to investigate molecular-level interactions and changes in functional groups, while SEM provides insight into the microstructural morphology and dispersion of plastic within the binder matrix. Additionally, Surface Free Energy measurements are applied to quantify cohesive bonding and assess moisture susceptibility.<\/p>\n

The findings demonstrate that waste plastic modification can significantly enhance binder properties, including improved microstructural stability and resistance to moisture damage. These improvements contribute to better overall pavement performance and durability.<\/p>\n

The goal of this research is to promote sustainable and resilient pavement solutions by integrating recycled materials into asphalt technology. By utilizing waste plastics, the study supports reduced environmental impact, improved infrastructure longevity, and more efficient resource use. Ultimately, this approach contributes to safer roads, lower maintenance costs, and a more sustainable transportation system while advancing expertise in innovative pavement materials.<\/p>\n
