EXPANDED POLYSTYRENE - A SUPERLIGHT FILL MATERIAL ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

When road embankments are constructed across deposits of soft clay or peat, both bearing capacity and settlement problems may be solved using blocks of expanded polystyrene (eps) as a fill material. Also when constructing roads on steep slopes, eps may be used to solve stability problems. 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. In Norway more than 100 road projects involving the use of polystyrene blocks have been successfully completed with volumes varying from a few hundred to several thousand cubic metres of eps. Some of these projects are described briefly. These include pavement construction over very soft clay ground, bridge abutments, vertical retaining walls, and bridge decks. Possible future uses are also discussed. For the covering abstract of the symposium see IRRD 818063.
