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).

Construction of Roman roads

The Romans varied the road construction to accommodate local materials and the terrain. Roman road consists of three layers: A bottom foundation layer, often of stone. A middle layer of softer material such as sand or gravel. A surface, or "metalling," usually a gravel, but sometimes paving stones. The upper layers of the road are always laid ...

Top Five Common Road Construction Methods - CBR Testing

Sep 28, 2017  Bituminous Road; Bitumen is the key material in this method. This method is the most preferred due to its flexibility. It made of four layers of bitumen. The bottom layer is the thickest and the subsequent three layers keep on thinning as the get to the top. One major advantage is its elasticity as it tends to acquire the shape of load above it.
