The Road Pavement Structure Engineering Essay
A road pavement is a structure of superimposed layers of selected and processed materials which is placed on the sub grade. Supporting the wheel loads applied to the carriageway and distributing them to the underlying sub grade is the main structural function of a pavement (O’Flaherty, 2002).

COMPONENT OF THE ROAD STRUCTURE SUBGRADE The subgrade is a layer of natural soil prepared to receive the layers of pavements materials placed over it. The loads on the pavement are ultimately received by the subgrade for dispersion to the earth mass. It is essential that at no time, the soil subgrade is overstressed.
