What Is Pavement? Types Of Road Pavement & Road ...

There are major two types of pavement based on their structure, 1. Flexible pavement. 2. Rigid Pavement. Flexible pavements, vehicular stress is transferred to subgrade through gain to gain contact of the aggregate through the granular structure. These types of road have less flexural strength, acts like a flexible sheet (e.g. bituminous road). In the case of rigid pavement, vehicle loads are ...

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).

2. Stresses and strains in road structures - ROADEX Network

In an ideal road structure, the modulus of the materials in the pavement layers should decrease from top to bottom. This is because the closer the material is to the surface; the greater will be the stress caused by the wheel load. A stiffer material will spread the load better over the layer below.

Dynamic stress and deformation of a layered road structure ...

01/08/2012· By using dynamic calculations, the influences of the road structure layer properties, such as the Young’s modulus and pavement thickness, on the response of road system were investigated. The main conclusions of this study can be summarised as follows: 1. The values of vertical stresses and elastic deformations in the case of dynamics are higher than those of static over the entire range of ...

Road construction - Designing Buildings Wiki

Road construction techniques were gradually improved by the study of road traffic, stone thickness, road alignment, and slope gradients, developing to use stones that were laid in a regular, compact design, and covered with smaller stones to produce a solid layer. Modern roads tend to be constructed using asphalt and/or concrete.

In an ideal road structure, the modulus of the materials in the pavement layers should decrease from top to bottom. This is because the closer the material is to the surface; the greater will be the stress caused by the wheel load. A stiffer material will spread the load better over the layer below.

CHAPTER 3 ROAD DESIGN

An improvement over a simple dirt road consists of a ballast layer over a subgrade, with or without a wearing course. The function of the ballast layer is to distribute the wheel load to pressures the subsoil can withstand. The wearing course provides a smooth running surface and also seals the surface to protect the subgrade from surface water infiltration. The wearing course can either be a ...

The pavement or wearing course is the top layer of a road. One function for the pavement is to provide a waterproof covering for the lower pavement structure. This can be achieved if the pavement is impermeable and has no cracks. The topmost wearing course must also have an adequate cross fall to lead water (from rain, melting snow or ice) immediately away from the road surface. The ...
