Challenge Problems
Push your limits with advanced challenges
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?
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.
