2.11.2. Significance

Try these first

1. 1.

   What does the k-value measure?

   Hint

   Think about how load affects ground movement.

2. 2.

   Explain what a Plate Load Test is.

   Hint

   Consider how we assess the ground's response.

3. 3.

   What does the k-value indicate in pavement design?

   • Soil Plasticity
   • Soil Stiffness
   • Soil Moisture

   Hint

   Think about how the ground reacts to heavy loads.

4. 4.

   True or False: A higher k-value is preferable in pavement design.

   • True
   • False

   Hint

   Remember what a stiffer soil means for structures above.

5. 5.

   You have performed a Plate Load Test at a construction site. A load of 5000 lb resulted in a settlement of 2 inches. Determine the k-value and discuss its implications for pavement design.

   Hint

   Use the formula k = Load intensity / Settlement.

6. 6.

   A highway was built on an area with varying moisture content. After heavy rains, significant settlement occurred. Propose a remediation plan that includes how to reassess the k-value.

   Hint

   Focus on environmental factors that affect ground stability.
