A standard concrete pavement section consists of a concrete wearing surface placed over a compacted road base and subgrade. A schedule below the section indicates layer thicknesses for standard and heavy duty applications, requiring a six-and-a-half-inch concrete layer and a four-inch road base for standard conditions. Notes on the drawing direct the builder to refer to the project soils report for specific section requirements that override standard dimensions.
