The client’s principal requirements for the construction of a piled embankment concern: deformations/differential deformations, external loads, reliability class, service life / need for maintenance, limitations in use and effect on immediate environment. This chapter presents additional principles and details concerning: guideline, pile location tolerance, support of the geosynthetic reinforcement by the subsoil, surface water and applicability of the design. Horizontal loads arising from braking forces should be taken into account at the end of a road structure, or in a bend. This also applies to centrifugal forces from the traffic that is the result of turning through an arc radius. Dynamic loads on high-strength geosynthetic reinforcement made of PET, PVA or PP causes no change to the tensile strength of these materials. The partial factors used for the calculation of the geosynthetic reinforcement have also been derived based on Monte Carlo analyses.
