3 cards from this section. Quick, good the night before a test.
Describe the impact of more axles on pavement stress.
Think about how weight is spread across the pavement when more wheels are present.
What is contact pressure?
Consider how wheel load affects the pavement directly.
What is the primary benefit of having multiple axles on a vehicle in terms of pavement design?
Consider how weight translates into pressure on single vs. multiple points.
True or False: Contact pressure increases as the number of axles decreases.
Think about how weight is applied to a smaller area with fewer wheels.
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.
Consider the distribution of weight as you change the configuration.
Evaluate the potential reduction in pavement lifespan when subjected to a constant cumulative load over time. What could be implemented to mitigate this risk?
Think about how materials can interact with loads over time.
