The East highway by-pass project of Troyes in France crosses a peat bog where the thickness of peat is approximately 2 to 3 m. The maximum design height of the embankment is approximately 7 m. The use of a geotextile reinforced embankment was selected among other techniques. Prior to the construction of the actual highway embankment, an experimental embankment was constructed and monitored. Measurements of foundation soil settlements, horizontal soil displacements at the bottom of the embankment and geotextile strains are discussed. The experimental embankment showed that the primary goal which was the removal of peat by punching was not reached while the global stability was improved. It appears that the rate of settlement versus time is rather uniform
