Road Pavement LGAM Knowledge Base

The Road Pavement is the portion of the road located directly above the subgrade, and beneath any wearing surface.In urban areas it is often bordered by kerb & channel, and in rural areas by road shoulders.It is typically constructed from compacted imported material such as crushed rock. The road pavement is sometimes broken up into two components, namely the base and the sub-base.
