Applications of Viscoelasticity

Drr. Pouria Hajikarimi is an Assistant Professor and Director of the Advanced Pavement Laboratory in the Department of Civil and Environmental Engineering at Amirkabir University of Technology (Tehran Polytechnic). His primary research interests include both experimental and numerical investigations of homogeneous and heterogeneous viscoelastic materials. Additionally, he focuses on the utilization of bio-based and waste substances in various construction materials such as asphalt mixtures, cementitious concrete, and geopolymers. Dr. Hajikarimi has authored two textbooks, namely “Applications of viscoelasticity: Bituminous materials characterization and modeling” and “Constructional Viscoelastic Composite Materials: Theory and Application,” both published by Elsevier and Springer, respectively. With a publication record exceeding 80 high-quality journal papers, his contributions span diverse topics related to flexible and rigid pavements. He has also been engaged in various industrial projects and research initiatives in fields such as the production of rejuvenators for use in recycled asphalt mixtures, strategies for utilizing RAP to promote sustainable development and reduce carbon dioxide emissions, laboratory and numerical modeling of recycled asphalt mixtures with an environmental approach, and the utilization of wastewater treatment plant sludge for brick production. Some of these projects, in addition to resulting in scholarly publications, have led to patent registration and technological advancements in specific domains. Prof. Fereidoon Moghadas Nejad is a well-known professor and a national figure in pavement engineering in Iran due to his high-quality research and practical works in the field of asphalt binder modification, construction of highways and railways, and concrete pavements. Additionally, he has lots of experience, and it can be said that he was the pioneer of establishing a pavement management system (PMS) in several cities of Iran. During his academic life, He supervised 10 Ph.D. dissertations and 80 master theses up to now, which resulted in more than 15 textbooks and chapters (in Persian and English), more than 190 journal papers and 200 international and national conference papers. He also contributed in 21 national and one US patents.
