QUESTION 2 A 7.2% upgrade meets a 1.4% upgrade. The operating speed for the road is 100 km/h. The chainage and reduced levels 80 m after the vertical curve are 1420.00m and 96.055m respectively. (a) Determine the vertical curve length to be adopted (round your answer to the nearest 50m). (b) Calculate the RL and chainage at TP1. (c) Calculate the RL on the gradeline and curve at chainage 1287.00m.
