Seyed Reza Omranian
- Research Expertise:During his master's and Ph.D., Seyed Reza Omranian concentrated mainly on asphalt mixture behavior, aging, bituminous materials characterization in terms of rheological, chemical, and mechanical performance, as well as pavement structure and mix designs. He was also involved in studies where warm mix additives were incorporated to produce asphalt mixtures in order to promote long-lasting pavements that produce at a lower energy consumption rate. Dealing with the challenges of using/replacing reclaimed asphalt pavement (RAP) in newly built pavements and investigating on the materials' recyclability instead of consuming all non-renewable resources was another side of his research. Considering the recent pavement performance challenges posed by climate change and demands for resilient pavement, Reza has expanded his research domain. He is now concentrating on the utilization of new technologies during pavement execution such as smart pavers and intelligent compactors to construct uniform and more durable pavements. His research also focuses on innovative approaches to constructing resilient roads that can withstand the effects of climate change. This promising strategy can maintain the continuity of pavements’ performance and recovery to the desired function throughout their designated service life. He has extended his horizon by reinforcing bituminous materials using different types of fibers. Investigation on the interface adhesive layer to enhance the bonding between pavement layers is also part of his research. Last but not least Omranian is currently working on a project to eliminate/reduce pollutants using photocatalytic semiconductor nanoparticles such as Titanium Dioxide (TiO2) in/on asphalt pavements without compromising bitumen and mixture performance.

- Users of research expertise:Civil Engineering is the foundation of the human world and provides the opportunity to innovate and create new aspects of science to solve challenges directly impacting our globe and people. Pavement engineering is the main aspect of infrastructure which plays a crucial role in all nations. My research and expertise can directly impact people's daily lives by enhancing road durability and riding quality which significantly reduces negative impacts on the environment. It can also be used for research in the universities and companies for further improvements of pavements, ports and airfields in terms of sustainability and climate resilience.
