Question 8 10 Points The elements of a reverse curve are as follows: 11 = 19.3 12 = 24.2 D = 2.8 D2 = 4.7 If STAPT = 25-228, determine STA PI. Add your answer Question 9 10 Points An ascending grade of 3% intersects another grade at STA 12+598 whose elevation is 577m. The change in grade is -0.15% per 20m station. The two grades are to be connected by a parabolic curve 800m long. Determine the elevation (m) of the summit. Add your answer Question 10 10 Points A 4.8% grade intersects a-1.2% grade at STA 5+180 at an elevation of 180m. A vertical curve of length 120m is to be run forward from the point of intersection, and a curve of length 80m is to be extended back forming an unsymmetrical curve. Determine the elevation (m) of the summit Add your answer
