Current Research Initiatives:
Dr. Bayat’s research interests include trenchless construction of underground and road infrastructures. As the NSERC IRC in Underground Trenchless Construction, Dr. Bayat will be researching methods to install and rehabilitate underground infrastructure, focusing on coldregion climates. Dr. Bayat will investigate risk factor and mitigation, microtunneling, pipejacking, the improvement of trenchless geotechnics, and the implementation of fibre-to-the-home connections.
As Director of the Consortium for Engineered Trenchless Technologies (CETT), Dr. Bayat’s research focuses on the technical and operational challenges associated with trenchless construction of underground infrastructure. Dr. Bayat’s research in CETT focuses on construction and operational challenges associated with Horizontal Directional Drilling (HDD), Pilot-Tube Micro Tunneling (PTMT), Pipe Bursting, Cured-in-Place Pipe (CIPP), fibre-to-thehome (FTTH) installations, and Underground Infrastructure Condition Assessment. As CETT’s research initiatives grow, so does its impact on the trenchless technology industry. Before Dr. Bayat’s initiatives, the University of Alberta had not been involved in underground trenchless research, but with his expertise, it is swiftly becoming a leader in these technologies.
Dr. Bayat is also lead researcher at the Integrated Road Research Facility (IRRF), which he helped form with provincial and municipal partners to investigate the impact of cold climates on pavement performance. The IRRF was formed with the goal of answering important questions about the impact of cold-climates on pavement performance, as well as test the feasibility of waste and recycled materials in road construction.
