2. A Vertical sag curve has a descending grade of -4.2% and an ascending grade of +3%
intersecting at station 10+azo whose elevation is 96m. The two grade lines are connected
by 260m vertical sag curve.
1). At what distance from P.C is the lowest point of the curve located?
2) calculate for the vertical offset of the point of intersection
3) If Im diameter culvert is placed at the lowest point of the curve with the
top of the culvert burled 0.70m below the subgrade, what will be the elevation
of the bottom of culvert?
