Applications of Viscoelasticity: Bituminous Materials Characterization and Modeling starts with an introduction to the theory of viscoelasticity, emphasizing its importance to various applications in material characterization and modeling. It next looks at constitutive viscoelastic functions, outlines basic equations for different loading conditions, and introduces the Boltzmann superposition principle, relaxation modulus, and creep compliance. Mechanical models, including integer-order and fractional-order are studied next, featuring real experimentation data alongside the benefits and drawbacks of using each model in various real-world scenarios. The book then covers the correspondence principle, followed by time-temperature superposition, featuring a simple procedure to construct a real master curve and challenges that might be encountered. The concluding chapters cover the Hopkins and Hamming, Park and Kim, and General Power law methods for interconversion of constitutive viscoelastic functions, applications of viscoelasticity for experimental tests, and incremental form of viscoelastic relations for numerical modeling. The book also includes supplementary codes that users can duplicate and use in their own work.
Hajikarimi, Pouria: - 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.
