To specify the design control values for sideslopes
1 From the Cross Section menu, choose Design Control รค Edit Design Control to
display the Enter Station Range dialog box.
2 Enter the station range, and then click OK to display the Design Control dialog
box.
3 Click Slopes to display the Slope Control dialog box.
The Slope Control dialog box displays the cross section information for the
specified range of stations. Use this dialog box to set the slope parameters for
matching the template surfaces to the existing ground. The section processing
determines where the end condition lies for each side of the template and
applies either the cut or fill information.
4 Select or clear the Match Slopes OFF check box:
n
Clear the Match Slopes OFF check box to turn on all slopes for a specified
range of stations. The slopes are turned on by default.
n
Select the Match Slopes OFF check box to turn off all slopes for a specified
range of stations.
This option is useful when you are working with elevated roadways where
the only volumes of interest are the proposed materials, such as when a
section of the roadway passes over a bridge. No cut and fill areas or volumes
are generated for the range of stations where the match slope is turned off.
5 Select the Fill type for both the Left and Right slopes:
n
Simple: Choose the simple type to use a straight slope from the connection
point out of the template or the ditch base to where the slope matches into
the existing ground. When dealing with topsoil material, the slope is a
straighter line so the soil remains somewhat stationary. Right-of-way control
or benching can be applied to simple slopes.
n
Depth: Choose the depth type to use a single slope that varies for different
depths. For example, a fill situation of eight (8) feet may use a different slope
than a fill situation of five (5) feet. Right-of-way control or benching can be
