Success For 4th ICTG

Nearly 400 participants gathered for the virtual 4th International Conference on Transportation Geotechnics (ICTG).

The quadrennial event is a forum to share the latest thinking on geotechnics and address challenges in the design, construction and maintenance of facilities including roads, airfields and harbors to ensure infrastructures are safer, more cost-effective and sustainable.

It is the flagship event for the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee 202 on Transportation Geotechnics, and is supported by organizations including the IGS.

Highlights this year included a keynote speech from IGS President Chungsik Yoo, two ISSMGE and ASCE (American Society of Civil Engineers) lectures, six special lectures, more than 34 geosynthetic-themed paper presentations, and 176 oral presentations delivered in 38 plenary and breakout technical sessions.

The event was originally due to be a face-to-face conference in Chicago, USA, on August 29 to September 2, 2020. As the developing coronavirus situation affected worldwide travel – at least 70% of paper authors and delegates were expected to come from overseas – organizers made it a virtual event for May 24-27, 2021.

Conference chairman Erol Tutumluer, who is also a member of the IGS Technical Committee on Stabilization, an IGS Council Member and chairman of the IGS Publication Committee, hailed the conference’s success.


“We were determined to create an impactful event for our guests and delegates despite the disruption caused by the coronavirus pandemic. Thanks to the hard work of the University of Illinois at Urbana-Champaign conference team, our supporters and sponsors, we were able to create a stimulating virtual program that has made its mark on the transportation geotechnics landscape,” he said.

“With all my career achievements at UIUC dedicated to advancing the Transportation Geotechnics field and continual efforts to improve the recognition of this field by transportation and geotechnical engineers, it was very meaningful for me to bring the 4th ICTG to North America for the first time.”

The event received impressive feedback, with comments including:

“Antonio Gomes Correia [founding chairman of the ISSMGE TC 202] and Erol raised the visibility of this TG conference to new levels and hope the next one will be an excellent one.”

“Allow me to add my congratulations to you and your team for organising such an excellent event. I can only imagine what a rough ride planning and delivering this conference has been in the middle of this awful pandemic. The fact that you have delivered such an excellent event speaks volumes for your collective enthusiasm, dedication, hard work and ability.”

“Congratulations to Erol and the team for one of the best conferences (online or in-person) I have attended.”

The first ICTG was held in 2008 at Nottingham University, UK, followed by Sapporo, Hokkaido, Japan, in 2012, with Guimarães, Portugal, hosting the 3rd ICTG in 2016. The 5th ICTG is due to take place in Sydney, Australia, in 2024.

4th ICTG session recordings are now available to view until August 31, 2021. Register here for access.

Some 233 peer-reviewed papers are also in the process of being gathered in a three-volume Springer Proceedings Book to be available in August this year.
