2 cards from this section. Quick, good the night before a test.
What is the deflection angle in road surveying?
Think about the angle formed when two lines meet.
Draw a simple circular curve and label its elements.
Use a compass for accurate curves.
What is the primary purpose of transition curves?
Think about comfort and safety while making turns.
True or False: Super-elevation is not necessary on flat curves.
Consider how centrifugal force affects vehicles on curves.
A proposed road deflects 36 degrees and requires a transition radius determined at 100m. Calculate the length needed for the transition curve.
Ensure to check the conversion of degrees!
Calculate the maximum super-elevation required for a circular curve with a radius of 200m where a vehicle is traveling at 70km/h.
Remember to convert km/h to m/s first!
