2.2. Conditions for Granular Material Use

Try these first

1. 1.

   What is the primary purpose of soil modification?

   Hint

   Think about what happens before construction starts.

2. 2.

   Define CBR in relation to soil.

   Hint

   What does CBR stand for?

3. 3.

   What is the difference between soil modification and stabilization?

   • Modification increases soil strength.
   • Stabilization prepares a working platform.
   • Modification is for construction readiness; stabilization is for strength enhancement.
   • Both serve the same purpose.

   Hint

   Think about the purpose of each process.

4. 4.

   True or False: Geogrids can help reduce the thickness of aggregate layers in road construction.

   • True
   • False

   Hint

   Consider the flexibility of road design with geogrids.

5. 5.

   Given a project requiring four lanes of heavy truck traffic, CBR tests show a CBR of 1.0. Discuss the required soil treatment procedures.

   Hint

   Identify how the CBR value influences the treatment choice.

6. 6.

   A new road project must avoid any traffic disruption during construction. Describe a strategy considering soil stabilization techniques.

   Hint

   Think about methods which prioritize minimizing traffic delays.
