The new railway line running from Milano to Bologna crossed an area of compressible soils in the Parma area. In particular, the results of the site investigation at some locations suggested a more innovative solution from the classical approach was required to resolve potential settlement problems. At the instruction of the railway engineering company ITALFERR, the designer and the main contractor compared the classical deep and short pile foundations with concrete slab with a geosynthetic solution based on high tensile strength polyester based geogrids. A technical, construction and cost benefit analysis showed that the geosynthetic reinforced piled embankment designed in accordance with BS 8006 (1995) offered the best solution, with the final technical and design options left to the contractor. A full-scale site investigation program was carried out on the foundation soil. The first embankment was built in 2003 and the construction phase was fully monitored to verify the effectiveness of the design. Over the following two years many other railway embankments were built on the same line using this design with some small changes mainly related to the pile cap size.
