A pile embankment system, granulate embankment on piles , granulate embankment on slender piles (GSP) or Load Transfer Platform (LTP), consists of a field of (usually slender) piles, with an embankment on it. This usually consists of a granulate fill that is reinforced with a geosynthetic material. On top of that, the embankment can be further elevated with sand or a granulate. Finally, the pile embankment is finished with a foundation layer and a paving or railway track, and in some cases even a soil embankment founded on steel.
