How is the embankment height of a road calculated?
The embankment height is generally calculated as the difference in levels of finished road level and the original ground level, the subgrade, and the crust thickness at any given location. The bed is made ready to receive the fresh material for new construction by sprinkling water and doing a plane pass.
