This is a case study of the "EDO-EPS Method" developed by the Expanded Polystyrene Civil Engineering Method Development Organization.
The "EDO-EPS method" was used for the restoration work of highways that collapsed due to earthquakes. It effectively utilizes the ultra-lightweight, compressive strength, durability, and self-supporting properties of EDO-EPS blocks, making it applicable in areas where load reduction and soil pressure reduction are necessary, such as on soft ground, embankments in landslide-prone areas, widening embankments on slopes, and backfill for structures. Additionally, since it does not require large construction machinery, it alleviates concerns regarding proximity construction to important structures and the surrounding environment. Furthermore, because it minimizes alterations to the terrain, this method can significantly contribute to the preservation of the natural environment during route planning and construction of earth structures in mountainous areas.

Company information
The Expanded Polystyrene Civil Engineering Method Development Organization (EPS Development Organization, EDO) was established in 1986 with the aim of technically establishing and promoting the healthy development of ultra-lightweight embankment construction using expanded polystyrene (EDO-EPS method). To date, it has conducted comprehensive research in collaboration with research institutions from industry, government, and academia on material properties, design and construction methods, seismic design technology, and more, compiling the design and construction system of the method into a "Design and Construction Standards (Draft)" document.
