Imad L Al-Qadi

Professor

Research Description

Al-Qadi’s teaching, research, and consulting interests and expertise focus primarily on civil engineering and pavement materials, sustainability, highway and airfield pavement mechanics, advanced modeling, including viscoelastic response to tire loading, pavement fracture, tire–pavement interaction, tack coat application rate optimization, and modeling of pavement interface and interlayer systems (including geosynthetics); nondestructive testing evaluation, including ground penetrating radar signal analysis; infrastructure asset management systems, including pavement recycling optimization and pavement condition assessment, rehabilitation, and life-cycle assessment; transportation infrastructure instrumentation and full-scale accelerated testing; polymerized asphalt rheology; and forensic engineering and arbitration.

Awards and Honors

  • Dr. Al-Qadi’s graduate students received numerous awards from FHWA (Eisenhower fellows), FAA, AAPT, ASCE, ACPR, IAPA, ICT, WTS, UIUC CoE Mavis Award, Wiley Award, AAAEA, Society of Women Engineers, and many other organizations. He advised them throughout the award research requirements.
  • Advisor for many winning projects, including the FAA Design Competition for Universities on Airport and Operation and Maintenance, 2008 (won 1st and 3rd places) and 2009 (won 2nd place).
