Pavement Design
A highway pavement is a structure consisting of superimposed layer of processed materials above the natural soil sub-grade, whose primary function is to distribute the applied vehicle loads to the sub-grade. The pavement structure should be able to provide a surface of acceptable riding quality, adequate skid resistance, favorable light reflecting characteristics, and low noise pollution. Generally we have two types of pavements
1- Flexible Pavement: Flexible pavement will transmit wheel load stresses to the lower layers by grain-to-grain transfer through the points of contact in the granular structure.
2- Rigid Pavement: The one layer of material between the concrete and the sub-grade and this layer is known as a base or sub-base course.
