The concept of compaction has been widely used in the construction activities such as highways embankments, earth dams and others engineering structures where the loose soils must be compacted to increase the unit weights and thus increase the bearing capacity of the subjected soils. However, little intention has been directed towards understanding the influence of compaction energy on the behaviour of shear strength using consolidated drained triaxial test. This research was conducted to study the effect of different energy in compaction for 25 number of blows compare with 40 number of blows using Standard Proctor Test. Results shows that the effect of different energy in compaction is not too significant where the changes is merely about 1° only in effective friction angles. It is because during consolidation stage in triaxial, the effect of different energy has no influence on the specimens. During consolidation stages in triaxial, the soil particles rearrange to each other with different applied pressure thus eliminates the effect of different energy on the specimens due to compaction effort. © Published under licence by IOP Publishing Ltd.
