The reduced level at the intersection of a rising gradient of 2% and a falling gradient of -3% on a proposed road is 89.05m. Given that K value is 55. The throught chainage of the intersection point is 4330m and proposed vertical curve is to have equal tangent, calculate: a) The throught chainage of the points of the vertical curve if the minimum required length is to be used (LV ) and the vertical curve setting out data at 20 metres exact interval. b) The chainage and reduced level of the highest point on the curve. c) Through chainage at highest point was located exactly under a bridge, if the RL of soffit is 92.90m, calculate the headroom based on proposed vertical curve design.
