Concept explainers

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.

Question

For the intersection curve (R = 35 ft) at Main Street, station A (0 + 52) to station D:
a. Compute the length of arc.
b. Determine the curb-line gradient (percentage) from A to D.
c. Determine the proposed curb elevations at stations B and C; B and C divide the arc into
three equal sections: AB = BC = CD.
d. Using the grade stake elevations shown in the chart below, determine the cuts/fills (ft and
in.) for stations B, C, and D.
