The following prompt is displayed:
Use curve correction (Yes/No) <Yes>:
6 Specify whether to use curve correction:
n
Type Y to use curve correction.
n
Type N to skip this option.
In normal volume calculations, the length between the end areas on horizontal
curves is taken from the length along the centerline curve. With curve
correction in use, the length is taken from the path of the average centroid of
the areas for a more accurate result.
The following prompt is displayed:
Use volume adjustment factors (Yes/No) <Yes>:
7 Specify whether to use volume adjustment factors:
n
Type Y to use volume adjustment factors. You are then prompted for the cut
and fill adjustment factors.
n
Type N to skip this option.
NOTE
For a material that expands 15 percent, enter the value
1.15
. For a
material that shrinks to 93 percent of its original value, enter the value
0.93
. A factor of 1.00 does not adjust the volumes.
8 Specify the range of stations.
The defaults for the beginning and ending stations are based on the beginning and
ending stations of the current alignment. Accept the default, or enter a different
range of stations. The command calculates the data and outputs it to the file.
