Bituminous layer is laid over the base course to ensure that rainwater does not damage the base, that moving traffic does not remove the metal and other material. The Bituminous layer also provides for dust free and comfortable riding.

Many types of Bituminous layers are constructed. Some layers act as base course and some act as surface course only. Keeping the traffic conditions on rural roads in view, the Bituminous layer for works under Pradhan Mantri Gram Sadak Yojana is often provided only as surface course.

Bituminous surfacing is traditionally carried out manually. However, the surfacing done with hot mix and pavers ensures uniform thickness and good quality and is to be preferred.
