3 cards from this section. Quick, good the night before a test.
What is contact pressure?
Think about what a tire does when it is on the road.
How does wheel load affect pavement depth?
Consider the weight of the vehicles.
What is the primary factor affecting pavement design?
Think about what stresses a pavement the most.
True or False: Higher speeds of moving vehicles decrease the stress and deformation on pavement.
Consider how speed and time affect stress.
Given a truck with a total weight of 40 kN distributed on 4 wheels, calculate the contact pressure if the contact area per wheel is circular with a diameter of 0.6 m.
Remember the contact pressure formula and how to calculate the area of a circle.
Analyze a scenario where a pavement experiences 10,000 load applications of 80 kN each. Discuss how this may affect the pavement’s longevity, considering the cumulative effect.
Look into how repeated stresses contribute to material fatigue.
