Abstract

When roads are constructed across soft clay deposits or peat bogs, both bearing capacity and settlement problems may be solved using blocks of expanded polystyrene (EPS) as a fill material. The unit density of polystyrene is about 100 times lighter than ordinary fill material, and the material properties match the load conditions in a road structure. Today, close to 100 road projects involving the use of polystyrene blocks have been successfully completed in Norway with volumes varying from a few hundred to several thousand cubic metres.
