This cross-sectional drawing depicts a standard roadway pavement structure with three distinct construction layers. The road section spans 5 meters in width and features a centrally crowned profile with 1:30 slope for drainage and 1:2 side slopes at the shoulders. The pavement system consists of three technical layers: a top 100 mm layer of PCC (Plain Cement Concrete) M20 grade, an intermediate 100 mm layer of CC (Cement Concrete), and a base 250 mm layer of WBM (Water Bound Macadam). The entire structure rests on compacted earth surface, providing a stable foundation. The crown design facilitates surface water runoff while maintaining driving comfort; the steeper shoulder slopes help contain the structural layers while minimizing the footprint. This typical section follows standard highway engineering practices for secondary or collector roads with moderate traffic loading.
