Pavement Structure - Pavement Interactive

A flexible pavement structure is typically composed of several layers of material each of which receives the loads from the above layer, spreads them out, then passes them on to the layer below. Thus, the further down in the pavement structure a particular layer is, the less load (in terms of force per area) it must carry (see Figure 1). Figure 1.

Types of Pavements used in Road Construction

The pavement thickness worked out to be 425mm for the traffic parameter of 3 million standard axle (msa) for BN road and 480mm for the traffic parameter of 1.25 msa in case of AP road. The pavement compositions were then, worked out considering the strength of GBFS, GBFS subgrade soil/moorum mixes for the two roads.

Structural Behavior of Asphalt Pavements ScienceDirect

Pavement structure is a part of road structure, which consists of the following elements: subgrade, subbase course, base course, and asphalt layer, all of which directly bear the effects of heavy loads and environmental conditions. The basic requirements for pavement are durability, smoothness, and safety (ie, skid resistance).
