Equal-tangent crest vertical curve

Reference no: EM1383481

1) An equal-tangent crest vertical curve is designed with a PVI at station 110+00 and a PVC at station 107+43.3. if the high point is station 110+75.5 what is the design speed of he curve?

2) A vertical curve is designed for 55 mi/h and has an initial grade of +2.5% and a final grade of -1.0%. the PVT is at station 114+ 50. it is known that a point on the curve station 112 +35 is at elevation 245 ft. what is the stationing and elevation of PVC? what is the stationing and elevation of the high point on the curve?
