20.2.4. Moving loads

Try these first

1. 1.

   What term describes dynamic weights from vehicles as they travel over pavements?

   Hint

   It relates directly to traffic.

2. 2.

   How does speed influence pavement wear?

   Hint

   Think about how fast a vehicle travels.

3. 3.

   How does increasing vehicle speed affect pavement damage?

   • Increases damage
   • Decreases damage
   • Has no effect

   Hint

   Think about how pressure is applied on pavement.

4. 4.

   Repeated loads have what kind of impact on pavement?

   • True
   • False

   Hint

   Reflect on the concept of wear over time.

5. 5.

   If a vehicle experiences a speed increase from 10 km/h to 30 km/h, and the load per axle is 10 kN, analyze the potential change in pavement stress according to the principles discussed.

   Hint

   Refer to stress and deflection metrics to compare conditions.

6. 6.

   Design a pavement structure where dual rear wheels of a truck equate to single axle loads. Discuss the benefits of this approach in terms of load distribution.

   Hint

   Think about how spreading the load changes contact pressures.
