Enhancement of roadway embankment utilizing several techniques, such as cement columns and applying EPS (expanded polystyrene) Geofoam blocks as subbase materials, helps develop the efficiency of embankment performance under the applied traffic loading for local materials. A PLAXIS 3D (ver.20) finite element program is used for the simulation models of roadway embankments. The results showed that applying the cement column reduced the vertical deformation of the roadway embankment to (50mm) corresponding to approximately (58%) of the reference model. The EPS Geofoam blocks highly lowered the vertical deformation to (20mm) about (83%) of the reference model to those in the cement column. The EPS Geofoam blocks provide a convenient solution for improving the roadway embankment with an (83%) reduction in maximum vertical displacement and sustaining traffic loading on the pavement. The reduction in displacement is well done by utilizing the EPS Geofoam blocks in a granular layer of pavement embankment. The EPS Geofoam blocks acted better in reducing vertical stresses (about 22%) higher than the cement column. This benefits the use of EPS Geofoam blocks in the base layer to enhance roadway embankment against failure.
