Floating road construction on soft soil

Abstract The main problem of road construction on saturated soft soils is due to their low bearing capacity and large settlement. One the solutions such problems install piled box culverts-geofoam. In this study, pile culvert-geofoam was modelled as raft foundation. This experimental study conducted by making a prototype file foundation gradually loaded with maximum vertical load 20 kN. Different thicknesses geofoam were utilized in order observe influence thickness Furthermore, difference settlement also found when culvert constructed without geofoam. Thicker observed result smaller
