Question: A - 2 . 5 % grade meets a + 4 . 6 % grade at station 1 0 0 + 4 5 . 0

A -2.5% grade meets a +4.6% grade at station 100+45.00 and elevation 100.25. a) Using AASHTO determine
the minimum length vertical curve for design speed of 50mph, calculate the station of the PVC (BVC) and
the elevation of the middle point of the curve. b) Determine the same using the Caltrans Highway Design Manual.
