Fundamentals of Soil Compaction

Figure 4 Effects of compactive effort on compaction curves It can be seen from this figure that the compaction curve is not a unique soil characteristic. It depends on the compaction energy. For this reason it is important when giving values of (γdry)max and mopt to also specify the compaction procedure (for example, standard or modified).
