2 cards from this section. Quick, good the night before a test.
What does CVPD stand for?
Remember the context of traffic measurement.
What is the design CBR of the subgrade soil in our example?
Check the provided data about the soil condition.
What is the initial traffic for the pavement design in this example?
Revisit the input data at the start of the example.
Is the vehicle damage factor in this example greater than 2?
Think about what 'greater than 2' means in this context.
Given an initial traffic of 600 CVPD, a growth rate of 8% for 20 years, and a vehicle damage factor of 3, calculate the cumulative standard axles and propose a pavement thickness.
Follow through the method of calculating cumulative axles, just as we did in our previous sessions.
How would your design change if the design life were altered to only 10 years but the subgrade CBR remained the same at 4%?
What happens to the traffic load if the pavement life reduces?
