The Infrastructure Materials focus area at Oregon State University emphasizes the fundamental understanding of materials and property relationships, microstructural development and its impact on long-term performance, durability and sustainability of civil and construction engineering materials, principles of green construction and materials selection as well as rehabilitation, assessment and repair of infrastructure with a focus on materials aspects. Research opportunities abound and are supported in the suite of world-class Infrastructure Materials Laboratories.
Infrastructure Materials faculty and their specific areas of research are listed below:
Pavan Akula is interested in developing computational models using soil chemistry to determine soil-based infrastructure materials' resiliency. Additionally, his research reduces the net CO2 footprint of conventional construction methods through material optimization and novel construction techniques. Akula leverages interdisciplinary studies with people from soil science, materials science, computer science, and engineering to advance our understanding of making our infrastructure resilient and sustainable.
Erdem Coleri's research interests are in the areas of sustainable pavement materials and structures, energy efficient pavement design strategies, and infrastructure health monitoring using wireless sensor networks. His research focuses on modeling and testing in several areas of pavement technology including asphalt binder and mixture characterization, aggregate characterization, asphalt mix and structural design, concrete materials testing, and concrete pavement design. The ultimate goal of his research is to encourage the use of more sustainable pavement materials, such as permeable pavements, rubber asphalt, warm-mix asphalt technologies, recycled asphalt pavements, recycled concrete, and alternative cement binders.
Professor Jason Ideker’s research interests are in the area of early-age volume change of cement-based materials and concrete durability. His research group is actively investigating ways to reduce early-age cracking in high performance concrete and understanding volume change in alternative cementitious systems. As an internationally recognized expert in alkali-silica reaction (ASR), Dr. Ideker and his team investigate ways to improve and develop new ASR test methods that accurately reflect field performance. The group also develops fundamental knowledge about the mechanisms of ASR mitigation. Dr. Ideker also focuses on providing rapid and effective repair strategies, particularly related to material selection, for the aging infrastructure prevalent throughout the world.
Professor Burkan Isgor’s research and teaching interests include materials science of cement and concrete, corrosion, electrochemistry, surface science, computational materials science, and non-destructive model-assisted testing of materials and structures. The ultimate goal of his research is to develop integrated numerical and sensory tools for infrastructure owners and operators so that they can better evaluate the state of their assets and make informed decisions on their future. These tools help engineers manage infrastructure by allowing them to schedule maintenance, rehabilitation and replacement operations more efficiently and accurately so that their assets will be resilient against extreme conditions imposed by multiple sources of hazard. To develop this understanding he combines computational techniques and experimental methods to bridge length scales, from atomistic/nano-scale to macroscopic, so that one can include chemistry and physics at a fundamental level into endeavors for modeling and characterization of various material behavior.
Professor David Trejo's research focuses on the design and development of materials and systems for efficient construction processes and products. His interests focus on the design and development of systems that allow for accelerated and durable construction. Specific research projects have included development of precast overhang systems for safe, rapid, and durable bridge construction, assessment and modeling of segmental, post-tensioned bridges exhibiting strand corrosion, development of refractory materials for NASA’s launch complex, modeling and performance assessment of glass fiber-reinforced polymer (GFRP) concrete reinforcement, and many others. His teaching interests include heavy civil methods and processes, cementitious materials and systems, and durability of infrastructure systems. With almost 10 years of experience in the field, Dr. Trejo brings real-world applications into the classroom.
Jason Weiss' research and teaching focus are on value-added cement and concrete materials. His research team has developed innovative solutions to reduce concrete cracking through mixture design, shrinkage-reducing admixtures, and internal curing. They have been strongly involved in developing critical saturation models for freeze-thaw performance of concrete as well as providing specifications to reduce deicing salt damage. They have used electrical resistivity and the formation factor for assessing transport properties in concrete and developing models to predict the service life of concrete elements. Many of these tools have been adopted in the AASHTO R-101 performance specifications. The research team has fundamentally advanced carbon dioxide reduction. They have led studies on portland limestone cement that have been pivotal for their adoption and worked to develop the pozzolanic reactivity test (PRT) to develop quantitative methods to evaluate alternative SCMs and use them to optimize concrete mixtures. They are also actively involved in carbonation reaction research.
