A vertical symmetrical sag curve has a descending grade of - 4.2% and an ascending grade of +3%
intersecting at station 10 +020, whose elevation is 100 m. The two grade lines are connected by a 260
m vertical parabolic sag curve. (a) At what distance from the P.C. is the lowest point of the curve
located in m? (b) What is the vertical offset of the parabolic curve to the point of intersection of the
tangent grades in m. (c) If a 1 m. diameter culvert is placed at the lowest point of the curve with the top
of the culvert buried 0.60 m. below the subgrade, what will be the elevation of the invert of the culvert?
A symmetrical parabolic summit curve is to connect two roads with grades of
+4% and -2.5% that meet at station 18 + 420 at an elevation of 80.522 m. This
curve is to pass through a point P at station 18 + 400 at an elevation of 79.267 m.
Determine the elevation at the highest point on the curve.
A crest vertical curve connects a ?4.44% grade and a ?6.87% grade. The PVI is at station 43 ? 50.00 at an elevation of 1240.00 ft. The design speed is 30 mi/h.
