The Resilient and Sustainable Infrastructure Materials and Structures Laboratory is a research center focused on improving the knowledge base of materials and structures in the built environment and reengineering them for the future. The laboratory consists of experimental and computational facilities capable of evaluating the performance of existing and emerging construction materials and structures from the nanometer to the meter scale. Recent research has focused on the behavior of sustainable materials, such as recycled concrete aggregates (RCA), and resilient and damage-tolerant materials, such as high- performance fiber-reinforced concrete (HPFRC). Ongoing laboratory upgrades will allow for testing, characterization and modeling of other sustainable and resilient materials and structures. RCA materials are being used in pavement design, such as for the Illinois Tollway, to increase sustainability and reduce cost; HPFRCs are being deployed in bridge structures, such as the Pulaski Skyway Project, to decrease construction time, and in earthquake-resistant buildings, such as the Lincoln Square Expansion in Bellevue, Washington, to increase ductility and damage tolerance.
