Cross Sections A cross-sectional view  (fig. 15-16) that is given for a road project is a cutaway end view of a proposed station  between  the  left  slope  and  the  right  slope. Typical  cross  sections  are  plotted  at  any  intermediate place  where  there  is  a  distance  change  in  slope  along the center line where the natural ground profile and grade line correspond. The cross section displays the slope   limits,  the  slope  ratio,  and  the  horizontal distance  between  centerline  stakes  and  shoulder stakes.  It  also  shows  the  vertical  distance  of  the proposed  cut  or  fill  at  the  shoulder  and  centerline stakes. To compute the area of a cross section, you must first break it down into geometric figures (squares, triangles, etc.). (See fig. 15-17.) Compute each area separately, then total the results to obtain the total square  feet. Figure 15-16.—Cross section. Figure 15-17.—geometric sections of a cross section. 15-13
