Using Curve Correction

You can choose to use curve correction for volume calculations. 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 more

accurate results.

To use curve correction in volume calculations

1 From the Sheet Manager menu, choose Settings to display the Settings dialog

box.

2 Click the Section Preferences button to display the Cross Section Preferences

dialog box.

3 Under Volume and Area Control, select the Use Curve Correction check box to

use curve correction in volume calculations.

4 Click OK to exit the Cross Section Preferences dialog box.

5 Click OK to exit the Settings dialog box.

Changing the Cut Correction Value

To more accurately calculate cut volumes, you can specify a cut correction

value. The cut and fill correction values are used when computing volumes to

help determine the actual volume of material that needs to be removed from or

added to the site. For a material that expands 15%, enter the value 1.15.

Whereas, for a material that compacts to 93% of its original value, enter the

value 0.93. A factor of 1.00 does not adjust the volumes.
