Question

A
+9.00% grade intersects a -7.00% at station 50+70.26 and elevation
239.12 ft. A 400.00 ft. curve will be used to connect the two
grades. Compute:

(1) Station and elevation for the curve's endpoints

(2) Elevations and grades at full stations

(3) Station and elevation of the curve's highest and/or lowest
points

First, draw a sketch

Answer #1

Please Rate.

A 3.0% grade passing at station 20+00.00 at an elevation of
99.10 m meets a -2.0% grade passing at station 20+50.00 at an
elevation of 99.60 m. Please note that these two elevations and
stations DO NOT correspond to BVC and EVC.
a) Determine the station and elevation of the point of
intersection of the two grades.
b) If the highest point on the curve must lie at station
20+55.00, find the elevation of this point and the length of...

3. A
+2.35% grade meets a -2.20% grade at station 45+50.00 and elevation
695.00 feet (PIVC or VPI). An 800-foot (8 station) vertical curve
is planned. Draw a sketch and find the following:
a. The station and elevation of the
PCVC (BVC) (5 points)
b. The station and elevation of the
PTVC (EVC) (5 points)
c. The elevation (on the curve) of
station 44+00.00 (5 points)
d. The vertical offset for station
44+00.00 (5 points)
e. The station and...

A vertical curve has an incoming grade of +4.4% and an exit
grade of -2.2%. The length of the curve is 450.00 ft. The
intersection of the grades is at 10+00 and the elevation at that
point is 440.00.
Compute the elevation of the +00 points on the curve. Then
determine the location and elevation of the highest point on the
curve. If there is an existing bridge at this location over the
proposed road, and the elevation of its...
