Question
An equal-tangent vertical curve is to be constructed between grades of -3% and +2% (travelling left to right). The PVI is
located at 4+550.000 and has an elevation of 190m. An adjacent driveway to the new road being designed must maintain
accessibility. In order to abide this design constraint the elevation of the road at station 4+650.000 must be 193m. If the
vertical curve is designed using the general equation of a parabola: y = ax2
An equal-tangent vertical curve is to be constructed between grades of -3% and +2% (travelling
left to right). The PVI is located at 4+550.000 and has an elevation of 190m. An adjacent
driveway to the new road being designed must maintain accessibility. In order to abide this design
constraint the elevation of the road at station 4+650.000 must be 193m. If the vertical curve is
designed using the general equation of a parabola: y = az²+bx+c, which of the following
options presents the correct expression for the constant "c" (all equations are expressed in
metres)
c=190
c=193+0.015L
c=190+ 0.03L
c=190 +0.015L
c=193
