Road Pavement - an overview

Flexible pavements, in which bituminous bound materials are placed over granular base and sub-base layers and supported by subgrade. The load is absorbed and distributed with depth. • Rigid pavements, in which a concrete layer is placed over a subgrade with or without a sub-base layer. The rigid slab spreads the load over a large area.

Structural Design of Asphalt Pavements: Principles and

A three-layer asphalt pavement structure is assumed in this case, constituted with an asphalt layer, an unbound gran-ular layer and a subgrade. Two design variables (that is, asphalt and granular layer thicknesses) and two structural distresses (that is, fatigue and rutting) are considered. Figure 3 shows that various combinations of layer

Therefore, the pavement structure must be selected based on the construction traffic and sequence of construction. These pavements are generally built in phases. The first phase is the laying of the aggregate sub-base and asphalt base layers on the prepared subgrade or laying an asphalt base layer directly on the prepared subgrade.
