Dr. Alireza Roshan is a civil engineer and pavement materials researcher specializing in asphalt pavement materials, pavement surface characteristics, friction performance, and sustainable pavement engineering. He earned his Ph.D. in Civil Engineering from Missouri University of Science and Technology, where his research focused on evaluating pavement-compatible and cost-effective alternatives to conventional epoxy-based high-friction surface treatments (HFST). His research interests include asphalt-based surface treatments, pavement friction and texture, alternative binder systems, material degradation, pavement safety, and life-cycle cost analysis. Dr. Roshan’s research integrates laboratory experimentation, performance evaluation, and engineering analysis to investigate the durability, functionality, and cost-effectiveness of pavement materials under traffic and environmental conditions. His work has explored the use of alternative binders and aggregates in high-friction surface treatments, with an emphasis on improving compatibility with existing asphalt pavements, reducing maintenance costs, and supporting more sustainable pavement preservation strategies. He has contributed to peer-reviewed journal publications, transportation research reports, and presentations at national and international conferences. In addition to his academic research, Dr. Roshan works in pavement asset management and engineering with the Indiana Department of Transportation (INDOT)
