Question
An unsymmetrical parabolic curve has a forward tangent of -8% and a backward tangent o +5%. The length of the curve on the left side is 40m long while the right side is 60m long. The PC is at station 6 + 780 and has an elevation of 110m. An outcrop is found at station 6 + 800 has an elevation of 106.40m. Calculate the following: a. The height of fill needed to cover the outcrop b. elevation of curve at station 6 + 820 c. elevation of the highest point on the curve
