Preparation of Subgrade
➢Subgrade : Prepared earth surface on which a
pavement is placed or upon which the foundation of a
structure is built.
➢Sub soil: ‘Subsoil’ refers to the stratum of soil immediately
below surface soil or topsoil.
➢ Often this layer is overlooked, as most land management is
focused on topsoil, which can be altered drastically by cultivation
and other practices.
➢ 2-3% Camber in transverse.
