The paper describes the difficulties encountered during the design and construction of two different road embankments over marshy areas, both characterised by the presence of highly compressible soils and of a high water table.
The foundation layer of these embankments were reinforced with layers of geosynthetic reinforcement. The geological situation of the area, the problems encountered and the solutions found to solve these problems using geosynthetics are described, together with the design considerations about the effect of reinforcement and a final evaluation of the advantages provided by geosynthetics to the Contractor and the Client.
