ABSTRACT
This chapter presents the requirements for the reinforced embankment. It describes how the geosynthetic reinforcement should be designed. The primary function of the reinforced embankment is to transfer the greater part of the vertical load from the pavement or rail construction to the piles. The service life of the embankment is primarily governed by the service life of the geosynthetic reinforcement. A roll of geosynthetic reinforcement material is usually at most 5 m wide and 100 to 300 m long. Overlaps should be avoided in the longitudinal direction. The embankment fill should have properties that enable it to be placed and compacted properly. In practice, this means that it should consist of granular material. The chapter also describes influence of braking forces and centrifugal forces in bends on strain and tensile force. The lateral thrust is determined based on an assumed active soil pressure wedge that is built up from top of the embankment to the reinforcement.
