10 Questions
What is compaction in the context of geotechnical engineering?
Densification of soils by removal of air through the application of mechanical energy
Which of the following is NOT a reason why soils at a given site may be less than desirable for the intended purpose?
Low compressibility
What is often the most economical alternative for improving the properties of soil at a given site?
Stabilizing or improving the properties of the soil
In which scenario is compaction particularly important as an engineering process?
When soil is used as an engineering material, such as in earth dams
How is the degree of compaction measured?
In terms of its dry unit weight
Compaction is the densification of soils by removal of air through the application of mechanical energy. The degree of compaction is measured in terms of its dry unit ______
weight
SOIL COMPACTION 🖸 Compaction is also very important when soil is used as an engineering material, that is the structure itself is made of ______. Ex. ▪ Earth dams ▪ Highways ▪ Airfields ▪ etc.
soil
In Geotechnical engineering practice, the soils at a given site are often less than desirable for the intended purpose. They may be: ❑ Weak (strength) ❑ Highly ______ ❑ Have a high permeability
compressible
The third alternative may be in most cases the most economical alternative. There are different techniques for improvement of soils (This subject is covered in details in CE 486 “Improvement of Geotechnical Materials”). We will consider in this course only ______.
compaction

Study Notes
Soil Compaction
- Compaction is the densification of soils by removal of air through the application of mechanical energy.
Importance of Compaction
- Compaction is particularly important when soil is used as an engineering material, such as in the construction of earth dams, highways, airfields, etc.
Undesirable Soil Properties
- Soils at a given site may be less than desirable for the intended purpose due to being:
- Weak (strength)
- Highly compressible
- Having a high permeability
Improving Soil Properties
- The most economical alternative for improving soil properties is often compaction.
- There are different techniques for soil improvement, but only compaction will be considered in this course.
Measuring Compaction
- The degree of compaction is measured in terms of its dry unit weight.
