Plastic Waste for Sustainable Asphalt Roads

Filippo Giustozzi is an expert in road and airport pavement materials and is currently serving as Associate Professor at RMIT University (Australia). He is the co-chair of AKP00(2) – Sustainable and Resilient Pavements at the Transportation Research Board of National Academies of Sciences and Engineering in the United States. He completed his second PhD at Virginia Tech University (United States) in 2012. He has participated in several major road and airport construction projects as a consultant since 2008. Dr. Giustozzi is the lead investigator for the national Austroads project APT6305 'Use of Road-grade Recycled Plastics for Sustainable Asphalt Pavements', approved by the Transport and Infrastructure Council that brings together Commonwealth, State, Territory, and New Zealand Ministers. He also collaborates with several national and international road contractors and bitumen suppliers on a variety of research and field projects, mainly around polymer-modified bitumen and recycled materials for road applications. At RMIT University, he leads the Intelligent Materials for Road and Airport Pavements research group. Sabzoi Nizamuddin is currently working as a Research Fellow in Civil and Infrastructure Engineering at RMIT University (Australia). He received his PhD in 2019 from RMIT University. He was awarded the Research Excellence Award from RMIT University’s School of Engineering, based on the high quality and quantity of papers he published during his PhD. To date, he has been the author of more than 75 articles in peer-reviewed Scopus/SCI/ESCI-indexed journals, 5 book chapters for Elsevier and Springer, and has presented his findings at domestic and international conferences. Currently, he is a co-editor for 'Frontiers in Energy Research' and the 'International Journal of Environmental Research and Public Health'.
