applied to depth control slopes. Enter the depths and slopes using the Depth
Slopes command.
n
Stepped: Choose the stepped type to use variable slopes and benches as the
slope passes through different variable depth ranges. When the right-of-way
hold is on and the stepped slope exceeds the right-of-way, the stepped slope
values are ignored and a simple slope pins into the right-of-way. The
benching option (in the Design Control dialog) cannot be applied to stepped
slope types because benching is defined as part of the stepped slope criteria.
Enter the depths, slopes, bench widths, and bench cross grades using the
Stepped Slopes command.
6 Select the Cut type for both 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
applied to depth control slopes. Enter the depths and slopes using the Depth
Slopes command.
n
Stepped: Choose the stepped type to use variable slopes and benches as the
slope passes through different variable depth ranges. When the right-of-way
hold is on and the stepped slope exceeds the right-of-way, the stepped slope
values are ignored and a simple slope pins into the right-of-way. The
benching option (in the Design Control dialog box) cannot be applied to
stepped slope types because benching is defined as part of the stepped slope
criteria. Enter the depths, slopes, bench widths, and bench cross grades using
the Stepped Slopes command.
n
Surface: Use the surface slope type to apply different slope conditions
through different types of existing ground material (for example, rock,
gravel, and dirt). Multiple existing ground cross section surfaces are defined
by sampling from multiple surfaces or by defining subsurface depths with
the Edit Sections command. The surface the cut slope is passing through
determines the slope used. The surface type can also be used to create ledges
at places where the surface changes. This is useful for situations in which the
cut is passed through a layer of rock. This ledge can either follow the surface
or bench at a set grade.
When the right-of-way hold is on and the surface slope exceeds the right-of-
way, the surface slope values are ignored and a simple slope pins into the
right-of-way. Set the surface name, slope, and ledge width using the Surface
Slopes command. The benching option (in the Design Control dialog box)
cannot be applied to surface slope types since benching is defined as part of
the surface slope criteria.
7 If you are using simple slopes, then specify the typical and maximum slope
values. These parameters set the slopes for cut and fill situations on the left and
right side of the template. The typical and maximum slopes are used by simple
slopes. The typical slope is also used to determine the depth criteria in depth-
controlled slopes condition. The other two slope options only use these values
when the necessary data has not been inserted using the appropriate slope
editor. With simple slopes, the typical design slopes are used wherever possible.
