Geotextile reinforcement of embankments on peat

The effect of geotextile reinforcement on the stability and deformations of embankments constructed on peat, underlain by a firm base, is examined. Both end of construction and long-term conditions are considered. The effect of geotextile reinforcement is compared with the effect of alternative construction methods involving berms or light weight fill. The combined use of geotextiles with light weight fill is then considered. It is concluded that the use of either geotextile reinforcement or light weight fill may significantly improve embankment performance; however, the use of reinforcement in conjunction with light weight fill may be the most effective means of improving performance in regions where light weight fill is readily available.
