Abstract:

This paper reviewed the advantages of expandable polystyrene(EPS) geofoam in civil engineering applications, including excellent thermal insulation performance, low density and easy local construction, good mechanical properties, excellent stability and strong self-support. Application examples of EPS geofoam in the field of civil engineering were introduced, including subgrade insulation, bridgehead filling, high filling section road, road widening, man-made landscape, retaining wall seismic field and prevention of uneven settlement. In addition, the problems in the actual application of EPS geofoam and its application directions were briefly discussed.

Key words: expandable polystyrene, foam, civil engineering, application
