2 cards from this section. Quick, good the night before a test.
What does ESWL stand for?
Think about the significance of single vs dual wheel loads.
Why is load repetition important?
Consider what happens over time with repeated loads.
What does the ESWL help determine in pavement design?
Think about why we need to know how much load the pavement can bear.
Is the Equivalent Axle Load Factor necessary for pavement design?
Consider the variability of axle loads on roadways.
A dual axle truck has single wheels that experience loads of 2000 kg and 3000 kg. How do you calculate the total response on a pavement section?
Evaluate each axle’s impact using equivalent factors.
Design a flexible pavement for a highway expected to handle 12,000 standard axle loads over a design period of 20 years. Calculate traffic growth factors and expected performance under load.
Identify trends in traffic load growth to inform your design.
