Question 1

What is the primary benefit of having multiple axles on a vehicle in terms of pavement design?

  • Increased speed
  • Better load distribution
  • Higher contact pressure

💡 Hint: Consider how weight translates into pressure on single vs. multiple points.

Question 2

True or False: Contact pressure increases as the number of axles decreases.

  • True
  • False

💡 Hint: Think about how weight is applied to a smaller area with fewer wheels.

Challenge Problems

Push your limits with challenges.

Question 1

A delivery truck with a single rear axle often causes damage to neighborhood streets. Propose a redesign of the truck's axle configuration to minimize pavement impact.

💡 Hint: Consider the distribution of weight as you change the configuration.

Question 2

Evaluate the potential reduction in pavement lifespan when subjected to a constant cumulative load over time. What could be implemented to mitigate this risk?

💡 Hint: Think about how materials can interact with loads over time.
