Abstract: For the highway embankments over soft soils, the differential settlement between the end of bridge and the embankment is very often. The differential settlement is called "bumps at the ends of bridge". This paper presents a case history of soil improvement method for the highway embankment over soils and the measures used to minimize the bumps at the ends of the bridge. The construction settlement monitoring results are also presented in the paper.

Key words: dry cement soil mixing, bridge bumps, soil improvements, highway embankments
