Question 1
What formula is used to determine the length of a vertical curve?
- L = (g1 - g2) * r * 30
- L = g1 + g2 - 30
- L = g1 / g2 * 30
💡 Hint: Remember the relationship between grades and length.
Question 2
The RL of a point is lower if it has a negative grade.
- True
- False
💡 Hint: Think about the meaning of a negative grade.

Challenge Problems
Push your limits with challenges.
Question 1
Given a grade change from +1% to -3% over a 600 m stretch, calculate the length of the vertical curve and the RL for points located 120 m before and after the intersection.
💡 Hint: Can you apply the grade and distance effectively?
Question 2
A vertical curve connects two grades of +0.3% and -0.9%. Given the RI at the intersection is 310.5 m, calculate the RL at the midpoint of the curve with a length of 180 m.
💡 Hint: Break down how the elevation affects the drop specifically.
