Focus Area: Sustainable Infrastructure and Materials (SIM)

The research of Sustainable Infrastructure and Materials (SIM) group is focused on improving conditions and increasing the durability of infrastructure components in a sustainable context. Part of this research can be done through advanced work related to both cement- and asphalt-based materials and identifying their sustainable properties. In addition, transportation policies related to encouraging sustainability in infrastructure and facilitating their application at the State and local level are also being explored.


Traditionally, the infrastructure component of civil engineering has been viewed as contributing little to the concept of sustainability. However, recent advances in technology and analytical modeling, along with a departure from prescriptive specifications for building materials and contracts, have allowed for more prominent integration of sustainable concepts into the design and construction of transportation systems. Researchers from the VCASE SIM engage undergraduate and graduate students in externally funded research projects involving sustainability. Dr. Leslie McCarthy has conducted research projects involving warm mix asphalt, railway infrastructure, recycled materials for use in transportation infrastructure, asset management, new materials for context-sensitive solutions, and innovative project delivery and contracting techniques. Dr. Seri Park is a recognized expert on the use of Intelligent Transportation Systems (ITS) that promote congestion mitigation on our nation’s highways. Dr. Park’s research topics include real-time traffic control and management, traffic safety, as well as traffic sensor technology and application.
