20.2.2. Wheel load

Try these first

1. 1.

   What is wheel load?

   Hint

   Consider what happens when a vehicle is stationary on a pavement.

2. 2.

   Why are dual rear wheels used in commercial vehicles?

   Hint

   Think about load distribution for heavy vehicles.

3. 3.

   What primarily determines the depth of the pavement?

   • The type of soil
   • Wheel load
   • Pavement material

   Hint

   Think about load conditions.

4. 4.

   True or False: Dual rear wheels can help limit pavement stress.

   • True
   • False

   Hint

   Consider how loads are distributed.

5. 5.

   A truck with dual rear wheels exerts a combined load of 20 kN. If converted to an equivalent single wheel load, what is the assumed load per single wheel?

   Hint

   Consider how dual loads can be simplified.

6. 6.

   Explain the long-term effects on pavement if a vehicle travels consistently at creep speed (2 km/hr) versus normal highway speed (24 km/hr) over a set time.

   Hint

   Reflect on the impact of continuous stress on materials over time.
