You will the type and thickness of the base and surface materials, also use sections for staking out roads, for determining earthwork  requirements,  and  for  determining  how closely the completed road conforms to its original design. Typical Section In the construction of a road, certain conditions or requirements must be met. One requirement is that the shape and features of the road be as uniform as possible. This and other requirements are stipulated in the typical section for the road. (See fig. 3-6.) The typical section of a road shows exactly what the road should look like after it is constructed. It includes the crown, superelevation, ditch slope, cut slope, fill slope,  and  all  horizontal  widths  of  components,  such  as surface, shoulders, and ditches. Since slight deviations will   occur   during   construction,   a   tolerance   in construction  is  allowed.  However,  the  shape  and construction of the road should conform as closely as possible  to  the  typical  section.  (For  general  provisions and design criteria, refer to NAVFAC DM-5.5.) Typical  sections  are  prepared  for  both  straight  and curved portions of the road. The typical section for a curved portion of a road differs from the straight portion in that the shape of the roadbed is different. In a typical 3-8
