In recent years, expanded polystyrene (EPS) blocks have been utilized for a variety of applications including landslide mitigation. Due to uniform geometry and low unit weight, EPS blocks have proven versatile and cost effective, while at the same time eliminating hazards and construction difficulties associated with other types of lightweight fill materials. This paper describes both the global and internal design methodology as well as installation procedures associated with EPS blocks. Also included is a detailed case study of the Wingert Slide mitigation project. Wingert Slide was an area of historic instability that affected approximately 60 meters of U.S. Highway 287/26 in the Wind River Mountain Range near Togwotee Pass. Togwotee Pass connects Dubois and Jackson Hole, Wyoming and serves as one of the highest traveled thoroughfares from the eastern side of the Rocky Mountains to Grand Teton and Yellowstone National Park. After years of monitoring, the Wyoming Department of Transportation (WYDOT) decided to mitigate the slide area through utilization of EPS blocks. Approximately 2,450 cubic meters of overburden was replaced by the lightweight blocks, thus reducing the driving forces in the slide and consequently increasing stability. This was the first time in WYDOT history that EPS blocks were utilized to mitigate a landslide.
