2 cards from this section. Quick, good the night before a test.
What is the main purpose of friction in pavement design?
Think about vehicle movement and control.
What does an unevenness index below 1500 mm/km signify?
Is lower better or worse when measuring unevenness?
What is one major factor affecting pavement friction?
Think about the surface on which vehicles drive.
True or False: Uneven pavement can increase vehicle wear.
Consider how rough surfaces affect movement.
Given a road with a friction coefficient of 0.35, calculate the safe speed limit for a vehicle with a maximum deceleration of 4 m/s². Discuss the implications of increasing load on this friction value.
Consider the physics of force and friction in relation to speed.
Analyze how uneven roads can affect fuel efficiency in vehicles over time. Discuss potential long-term effects on maintenance and safety.
Think about how energy efficiency relates to surface conditions.
