vertical road was designed with three tangent lines having a grade of -7.8%, 3.7%, and -2.1%, consecutively. "he intersections of the three lines are known to be V1 and V2 having an elevation of 227.96m and 201.72m espectively. The said tangent lines will be connected by a sag and a summit unsymmetrical parabolic curve which meets at point A having an elevation of 216.04m above sea level. The L1 of the sag curve is 104.68m and the maximum offset of the summit curve is 0.22 multiplied to the maximum offset of the sag curve. Point Ais located at the line that connects the two vertices. What is the total length of the designed vertical roads in meters?

Transcribed Image Text:Avertical road was designed with three tangent lines having a grade of -7.8%, 3.7%, and -2.1%, consecutively.
The intersections of the three lines are known to be V1 and V2 having an elevation of 227.96m and 201.72m
respectively. The said tangent lines will be connected by a sag and a summit unsymmetrical parabolic curve
which meets at point A having an elevation of 216.04m above sca level. The L1 of the sag curve is 104.68m
and the maximum offset of the summit curve is 0.22 multiplied to the maximum offset of the sag curve Point
A is located at the line that connects the two vertices.
What is the total length of the designed vertical roads in meters?
