Settlement Behind Bridge Abutments. The Performance of a Silty Clay Fill in an Approach Embankment on the M4 Motorway
The Report describes an investigation in which the performance of a silty clay fill, placed to complete the approach embankment to one of the abutments of a bridge, was compared directly with the performance of a sandy gravel filling, at the other abutment. The construction of the enbankments was carefully observed and records of the settlement of the road surface and the subsoil were obtained. It was found that although the silty clay filling was particularly well compacted settlements of up to 45mm subsequently occurred within the fill material after the road was completed. After a period of about 4 1/2 years movement within the fill had practically ceased but settlement of the subsoil was however still continuing at a rate of about 5mm per year due to the slow consolidation of the underlying London clay.
