Question
An unsymmetrical parabolic curve has a forward tangent of -8% and a back tangent of +5%. The length of the curve on the left side of the curve is 40 meters long while that of the right side is 60 meters long. The BVC is at station 6+780 and elevation 110 meters. Determine the height of fill at the outcrop at station 6+810 with a ground elevation of 108.40 meters. Determine the elevation of the curve at station 6+820 meters. Determine the turning point of the curve.
