Alireza Samieadel finished his master’s study at Amirkabir University of Technology studying life cycle assessment of road pavements and developing a sustainability index for pavements. He started his PhD at Arizona State University in 2015 working on multi-scale characterization of asphalt and use of sustainable modifiers to achieve a more sustainable asphalt binder with higher durability and lower environmental and economical impact. He then graduated in 2020 and started working as pavement strategist for Lancaster County in Nebraska for 2 years. Currently, he is working as civil design engineer for AECOM, one of the biggest consultant firms in the world.
In this presentation, a newly used approach is presented to use a multi-scale study of asphalt properties to better understand the role of different components of asphalt binder and how to leverage this understanding towards designing more durable and sustainable material for construction. This study uses a combination of experimental and theoretical means to identify asphalt’s most influential components and their molecular structures (known as SARA) and to study the correlation between these molecules’ interactions and mechanical properties of asphalt binder through conventional experimental tests. The goal for this study is to identify modifiers which can improve asphalt binder sustainability by increasing its durability, reduction of cost and alleviation of its environmental impact. In this research, using molecular simulation along with mechanical tests (RV, DSR, DTT, BBR) gave a better conception of how molecular level interactions, can affect macro-scale properties of asphalt binder and how this can help to better asphalt properties in future. The results of this study have been published in numerous journals and has been cited many times in relevant research.
