What is Pavement & Types of Pavement || Explained in Hindi 🔥

What is Pavement? (Road Pavement)
“A pavement is one type of hard surface made from durable surface material lay down on an area which is intended to carry vehicular or foot traffic”.

Types of Pavements (Road Pavement):

There are major two types of pavement based on their structure,

1. Flexible pavement.
2. Rigid Pavement.

Flexible Pavements:
In Flexible pavement, wheel loads are transferred to subgrade by grain-to-grain transfer through the points of contact in the granular structure. The wheel load stresses acting on the pavement are distributed to a larger area and the stress decreases with the depth. Considering this load distribution characteristic of flexible pavements, it has many layers.

Rigid Pavements:
This type of pavement is cable to transfer wheel load to a wider area as it has good flexural strength. In rigid pavement, there are not many layers of materials as in the case of flexible pavement. In rigid directly placed on a well-compacted subgrade or on a single layer of granular or stabilized material. As there is only a single layer between the concrete and the sub-grade, this layer can be called a base or sub-base course.
