Question 1.
Define axle load intensity in the context of pavement design.
Show hintHide hint
Think about what the axle does to the pavement.
Question 2.
What is meant by the repetition of loads?
Show hintHide hint
Consider how often vehicles drive over a road.
3Question 3.
What is axle load intensity?
- The weight of the vehicle
- The weight per axle
- The total weight of the vehicle divided by the number of axles
Show hintHide hint
Focus on individual axles, not the entire vehicle.
4Question 4.
True or False: Increased repetition of loads can lead to increased pavement deterioration.
- True
- False
Show hintHide hint
Think about wear and tear over time.
Question 5.
Given a hypothetical situation where a newly constructed interstate highway is experiencing excessive cracking due to frequent heavy truck traffic. Discuss design changes that would improve the pavement performance.
Show hintHide hint
Consider both structural and material improvements.
Question 6.
Calculate the required thickness for a concrete pavement section expected to bear a daily traffic load comprising 200 heavy trucks with each truck weighing approximately 30 tons. Assume a standard pavement design guideline suggests a depth of 150 mm per 100 tons.
