An embankment having a PI of 30%, LL of 40% and GI of 0, what is the degree of compaction for this kind of soil?

To determine the degree of compaction for a soil type characterized by a Plasticity Index (PI) of 30%, a Liquid Limit (LL) of 40%, and a Gravel Index (GI) of 0, it's essential to understand how these parameters relate to soil properties and compaction techniques.

The Plasticity Index indicates the range of moisture content over which the soil behaves plastically. A PI of 30% and an LL of 40% suggest that the soil is relatively plastic and suitable for compaction, but it requires careful management of moisture content to achieve optimal density.

The degree of compaction is often assessed with respect to the soil's maximum dry density and optimum moisture content, which can be derived from compaction tests like the Proctor test. For soils with characteristics similar to those described, a degree of compaction of around 95% is typically achievable.

This level of compaction reflects the optimal performance of the engineered fill, ensuring that the embankment is adequately dense to support structural loads while maintaining stability and minimizing settlement. Furthermore, achieving a 95% degree of compaction is often a standard specification in construction projects to ensure structural integrity and durability.

In summary, the choice indicating a 95% degree
