Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
Calculate the length of a vertical curve with a +2% and -1% grade and a rate of change of 1% per 30m.
💡 Hint: Use the formula L = (g1 - g2) * 30 / r.
Question 2
Easy
What is the reduced level (RL) if the chainage is 1000m and the height above datum is 50 m?
💡 Hint: Simply state the height as the RL.
