Geo-Congress 2022 – Conference presentations
Our research group will be presenting our ongoing works on an #analyticalapproach to estimate the bearing capacity of the geocell-reinforced foundation system; the #feasibility of using metakaolin-based geopolymers for stabilizing high-sulfate expansive soils; and the #effect of polymer emulsion treatment on permeability characteristics of subgrade soils. We are excited to meet you at #geocongress2022 conference, […]
Monitoring the safety of railroad tracks using cutting-edge sensors
Our research group is collaborating with Federal Railroad Administration (FRA) to monitor the safety of railroad tracks using cutting-edge sensors. As part of the ongoing project funded by FRA, Dr. Surya Congress (Lead-PI) and Dr. Anand Puppala (Co-PI) are deploying Unmanned Aerial Vehicles (UAVs) and using Computer Vision techniques to evaluate the safety conditions of the rail infrastructure in rural areas. […]

Dr. Puppala’s Group at Transportation Research Board (TRB) 101th Annual Meeting
Our group had a good Transportation Research Board (TRB) 101th Annual Meeting 2022 with three paper presentations and two posters presented by doctoral and post-doctoral students. Two of these papers on Resilient Characteristics of Polymer Emulsion Treated Sandy Soil and Evaluation of Geopolymer for Stabilization of Sulfate-Rich Expansive Soils for Supporting Pavement Infrastructure are recently […]
UAV for infrastructure asset management
The State of Alaska has the most beautiful and challenging terrains. Dr. Anand Puppala and Dr. Surya Congress are collaborating with the Alaska Department of Transportation & Public Facilities as part of a research project on using Unmanned Aerial Vehicles (UAV) for infrastructure asset management. The focus of this study is on bridge infrastructure and public facilities. If you are interested, […]
Journal Paper: Methodology for Resloping of Rock Slope Using 3D Models from UAV-CRP Technology
Safeguarding rail infrastructure has been one of the focus areas of Dr. Surya Congress’ research. Check out how we are deploying unmanned aerial vehicles (UAVs) for monitoring and safeguarding rail infrastructure assets in our recently published article: Congress, S. S. C., Puppala, A. J., Kumar, P., Banerjee, A., & Patil, U. (2021). Methodology for Resloping of Rock […]
Dr. Puppala’s Peck Lecture is published in JGGE and selected as Editor’s Choice
Dr. Puppala’s Peck Lecture 2020 paper titled “Performance Evaluation of Infrastructure on Problematic Expansive Soils: Characterization Challenges, Innovative Stabilization Designs, and Monitoring Methods” is published and featured in the Editor’s Choice section of the Journal of Geotechnical and Geoenvironmental Engineering (JGGE). Expansive soils have caused significant distress to civil infrastructure like pavement, retaining walls, slope, and residential buildings. […]
Journal Paper: Geotechnical Slope Stability and Rockfall Debris Related Safety Assessments of Rock Cuts Adjacent to a Rail Track Using Aerial Photogrammetry Data Analysis
Do you know, with 140,000 route miles, the freight rail network in the United States is widely considered the largest, safest, and most cost-efficient freight system in the world. It is necessary to monitor the rail corridors frequently to maintain safe operating conditions. Our research group is using cutting-edge sensors to monitor the rail corridors. […]
