4.3.1.2. Plate Load Test

Try these first

1. 1.

   What is the purpose of the Plate Load Test?

   Hint

   Think about what engineers need to know about the soil’s support capacity.

2. 2.

   What is the k-value?

   Hint

   Focus on what we assess during the Plate Load Test.

3. 3.

   What is the primary purpose of the Plate Load Test?

   • To measure moisture content
   • To determine the k-value
   • To assess soil color

   Hint

   Focus on what engineers need in terms of soil support.

4. 4.

   True or False: The Plate Load Test can be used for both flexible and rigid pavements.

   • True
   • False

   Hint

   Consider the specific applications of the test.

5. 5.

   A Plate Load Test results show a k-value of 150 kN/m³. If the pavement design requires a minimum of 200 kN/m³, what recommendations would you give for improving the subgrade?

   Hint

   Consider construction methods that enhance soil strength.

6. 6.

   During a Plate Load Test, a load of 80 kN caused a settlement of 20 mm. Calculate the k-value and discuss whether this soil is suitable for rigid pavement.

   Hint

   Convert the settlement to meters when calculating.
