4.3.3. Weight, axle configuration etc.

Try these first

1. 1.

   What is the role of vehicle weight in pavement design?

   Hint

   Think about what happens when a heavy vehicle travels on pavements.

2. 2.

   Define axle configuration.

   Hint

   Consider how this arrangement can vary between different vehicle types.

3. 3.

   What factor significantly influences the design of pavements?

   • Vehicle speed
   • Vehicle weight
   • Vehicle color

   Hint

   Think about how pavements need to support vehicles.

4. 4.

   True or False: An axle configuration is irrelevant in the context of vehicle performance.

   • True
   • False

   Hint

   Consider how weight is distributed across wheels.

5. 5.

   A delivery truck weighing 15,000 pounds with four axles needs to navigate a hilly area. Analyze how its weight and axle configuration affect the road conditions. What type of pavement should be considered?

   Hint

   Consider how vehicles affect pavements over time.

6. 6.

   Evaluate how different power-to-weight ratios affect a fleet of delivery vehicles with varying cargo weights. How might the fleet's performance change as weights increase?

   Hint

   Think about acceleration and speed management under load.
