Apply super .................Can be set to Yes if superelevation should be applied. Apply widen ................Should be set to Yes if widening should be applied. Cd.................................Is the code to be used for points set out at this point. The screen will be accepted automatically when you press {ď §}. The defined point can be considered to be joined to the previous template point in order to form the shape of the template.
25.11.4
Template sideslope definition Define as many template points as necessary to form the shape of the template. When you have finished, define sideslopes to join the edge of the template and the existing terrain at a catch point. When you choose Templ-Sideslope, this screen displays:
Define a cut grade and a fill grade in this screen. When you are setting out the road, the SRX determines whether you are in cut or fill and uses the appropriate grade to set out the sideslope. Define grades like you did in the Temp-Grade/Dist template point definition (Section 25.11.2, Template point by grade and distance, Page 25-25). However, the numbers are always positive. Cut grades are assumed to rise as they get further from the centerline, and fill grades are assumed to fall. Cut ...............................This grade will be applied to meet existing terrain when the template is in a cut situation Fill ................................This grade will be applied to meet existing terrain when the template is in a fill situation Press {ď §} to accept the screen.
25.12 Defining Road Cross-Section The cross-section of a road is defined by specifying templates to be applied along the horizontal and vertical alignments. Templates are defined independently of any survey job or road definition. The road crosssection definition allows you to associate one or more templates with a road's horizontal and vertical alignment. NOTE
SRX
As roads are interpolated between defined cross-sections, you must have a cross-section defined at both the start and the end of a road.
