Consider how tightly packed the soil becomes.
What is the role of admixtures in soil?
Consider what the term 'admixture' implies.
True or False: Compacted dry soils have greater shear strength than wet compacted soils.
Recall the impacts of moisture on soil structure.

Explore the differences between dry and wet methods.
A geotechnical engineer finds that a clayey soil exhibits high pore pressures during excavation. What methods can the engineer implement to lower these pore pressures effectively?
