1.3.2. Suitability of Methods

Try these first

1. 1.

   What happens to compacted density as water content increases up to OMC?

   Hint

   Remember the point before the optimum.

2. 2.

   Define Maximum Dry Density.

   Hint

   What does it stand for again?

3. 3.

   What is the effect of increasing water content on compacted density up to OMC?

   • Increases
   • Decreases
   • No effect

   Hint

   Think of how water helps particles connect until a point.

4. 4.

   True or False: Coarse-grained soils achieve higher density at lower moisture content than fine-grained soils.

   • True
   • False

   Hint

   Recall the properties of different soil types.

5. 5.

   A construction site has both sandy and clay soils. Devise an approach for testing MDD for each type of soil.

   Hint

   Think of the specific needs of each soil type.

6. 6.

   Analyze the implications of excessive compaction on fine-grained soils in terms of structural integrity and moisture retention.

   Hint

   Consider what happens when soil particles are too tightly packed.
