The 3rd International Symposium on Transportation Soil Engineering in Cold Regions was held at Gui-De City, China on July 6-7, 2017. The symposium was organized by Qinghai Research Institute of Transportation under the auspices of TC202 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and AFP50, Committee on Seasonal Climatic Effects on Transportation Infrastructure of Transportation Research Board (TRB), also supported by the Chinese Transportation Geotechnics Committee.

Technical sessions themes:
1. Mechanical behavior of soil and aggregate
2. Diagnosis and Mitigation of Soil Structure Distress in Cold Regions
3. Coupled modeling of mechanical and physical processes
4. Frost heave and thaw weakening of subgrade, ballasted subgrade and base of slab track
5. Field experiments in roadway embankments
6. Dynamic/seismic behavior of transportation infrastructure
7. Soil-structure interaction related to transportation environment and infrastructure
8. Experience in the construction and maintenance of subgrade in cold region

The conference proceedings contain 35 peer-reviewed papers, which have been included in Jounral of Sciences in Cold and Arid Regions (indexed by ESCI) and Journal of Chang’an University- Natural Science Edition (indexed by Scopus).

Following the two days’ meeting program, the technical tour to Guide National Geological Park and visiting of Qinghai Research Institute of Transportation in Xining city was held for all conference participants and their accompanying persons. The BBQ and dancing party was held on the second evening.

Prof. Andrey Petriaev and Prof. Yang Zhaohui thanked all the participants and announced that the upcoming “4th International Symposium on Transportation Soil Engineering in Cold Regions” will be held in Saint-Petersburg (Russia) on May 20th~23rd, 2019.
