Proctor compaction test in a mold ofvolume V = 945 cm3. The observations recorded are asfollows:
- What are the values of maximum dry unit weight and the optimummoisture content? [10 DEGREES]
- Draw 100% saturation line.[2 DEGREES]
Q3.Differentiate:
- Compaction and consolidation, and [2]
- Standard Proctor and modified Proctor tests.[3]
Q4.Draw an ideal 'compaction curve'and discuss the effect of moisture on the dry unit weight ofsoil.[3]
