A REINFORCED ROAD EMBANKMENT ON SOFT SOIL

A 60 m long stretch of a bridge approach embankment, which rises 3.5 m above the original ground level has been reinforced using plastic geogrids. The subsoil is mainly soft clay, the top layers having a high organic content. The reinforcement is placed in one and partly two layers under the embankment. The behaviour of the constructed embankment indicates that even a rather weak reinforcement increases the stability sufficiently. The relative settlement profiles of the embankment are about the same in cross-sections with and without reinforcement. A thin layer of reinforcement does obviously not have significant effect on settlement. (Author/TRRL)
