Cross Section of Road

The document outlines the typical cross-section of the proposed stage strengthening of an existing pavement from 0 to 49 km of NH-2B in West Bengal. It shows the existing layers including a 150mm bituminous layer, 250mm WMM/WBM layer, and 433mm base course and sub-base course. It proposes adding a 200mm hard shoulder, 40mm bituminous concrete layer, and 50mm thick DBM layer with specified slopes. The cross-section varies from 0-27km with a 9m width and from 27-49km with a 7m width.
