Effect of Compaction to Increase the Critical Height of a Slope without any Support

Embankment is a common way to raise ground level of any construction. Raising the ground level will also help structure from being flooded, flood especially in major city such as in Capital City of Indonesia, Jakarta, is a yearly problem. On the other hand, embankment will also be a problem if not handle carefully. Clay and sand can be used as materials. Properties of material that should be investigate before the materials being used are cohesion and angle of friction. Beside selection of high quality materials, compaction can also help embankment from failure. When the materials get well-compacted the chance of sliding should be lower. This study analyse the correlation whether well-compacted material can have higher critical height and the result can be imply on the construction site as not every embankment need retaining structure to be stable but only by compaction the embankment can withstand by it self.
