Dr.Bayat’s research interests include road infrastructure and underground trenchless construction. As Director of the Consortium for Engineered Trenchless Technologies (CETT), Dr.Bayat’s research focuses on the technical and operational challenges associated with Horizontal Directional Drilling (HDD), Pilot-tube Micro Tunneling (PTMT) and Underground Infrastructure Condition Assessment. He leads research at the Integrated Road Research Facility, which he helped form with provincial and municipal partners, to investigate the performance of different materials for road embankments and insulation layers in cold-climate regions. Other research projects in road infrastructure include: Mechanistic-Empirical pavement design, development and characterization of road materials and pavement performance for cold regions, winter road maintenance, and weigh in motion accuracy. Dr.Bayat is also involved in developing several full-scale field instrumentation and monitoring programs to measure soil and pavement responses under a variety of dynamic loads and environmental conditions.
