Road Structure Layer

Typical Road Structure Cross Section Sub Grade, Base

a. Function of Sub base in Road Cross Section. It enables traffic stresses to be reduced to acceptable levels in sub-grade in the Road Cross Section so that excessive deformation is prevented. It acts as a working plate form for the construction of upper pavement layers. Acts as a drainage layer, by protecting the sub grade from wetting up.
