The measurement of compaction through field density test in the embankment pit strata

The soil should have sufficient strength, be relatively incompressible so that future settlement will not be excessive, maintain a constant volume change against variable water content or other factors, be resistant to deterioration, and possess proper permeability. Standard test had been introduced...

Civil engineering (General) The soil should have sufficient strength, be relatively incompressible so that future settlement will not be excessive, maintain a constant volume change against variable water content or other factors, be resistant to deterioration, and possess proper permeability. Standard test had been introduced to determine the compaction percentage especially at the embankment area.

In addition, the percentage of consolidation of soft soil under the embankment and strength characteristic of the embankment layer had been considered. The result showed that the cut ground obtained high moisture content average 28% higher the Optimum Moisture Content (OMC) and consequently resulting to a lower range of 90% compaction.
