A section of a two-lane highway (3.60 meter lanes) is designed for 120km/h. At one point a vertical curve connects a 2.5% and +1.5 % grade. The PVT of this curve is at station 100+000. It is known that a horizontal curve starts (has PC) 89.6 meters before the vertical curve's PVC. If the super elevation of the horizontal curve is 0.08 and the central angle is 38 degrees, what is the station of the PT?

Expert Solution

Step 1

According to given data

A section of a two-lane highway (3.60 meter lanes) is designed for 120km/h.
At one point a vertical curve connects a 2.5% and +1.5 % grade.
The PVT of this curve is at station 100+000.
It is known that a horizontal curve starts (has PC) 89.6 meters before the vertical curve's PVC.
If the super elevation of the horizontal curve is 0.08 and the central angle is 38 degrees,

To find-
what is the station of the PT?
