Question 2 (20 marks) A vertical sag curve 220 m long connects a falling gradient of 5 in 100 and a rising gradient of 3 in 100. The RL and chainage of the gradient intersection point (I) is 90m and 500.00m respectively. Calculate the reduced level (RL) of the points at 20 m interval along the curve. Chainage (m) x Offset (m) y offset Point Curve RL (m) Question 2 (20 marks) A vertical sag curve 220 m long connects a falling gradient of 5 in 100 and a rising gradient of 3 in 100.
