A method widely used in Scandinavia for road construction over marshy ground is embankment piling, where piles are driven, capped with individual slabs, and the embankment constructed on top. For this method to be successful, the following conditions must be satisfied: (1) ground level below the slabs must remain unchanged. Piles are cut off at ground level, and the slabs must cover at least 35-50% of the piled area to prevent settlement of the embankment. (2) the fill on the slabs must have high friction. This is accomplished by using crushed rock or gravel. Relative displacement of piles is prevented by connecting straps. (3) piles must resist the earth pressures due to the embankment. This requires careful analysis at all stages of construction. (4) horizontal reaction from the piles must be resisted by the fill. This means that the number of raking piles must be limited, and check calculations made. The cost of this method is only about 50% of piling with a continuous capping slab, and it has been used successfully in hundreds of cases. Some embankments have however had to be reconstructed due to excessive settlement. This is probably due to the application of the method to increasingly unfavourable ground conditions without proper analysis. /TRRL/
