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.
A road surface (British English), or pavement (American English), is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway.In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these have mostly been replaced by asphalt or concrete laid on a compacted base course.
