A road surface or pavement is a permanent surface material that is placed in an area intended for barefoot or road traffic, i.e. on the path. In recent years, granite, cobblestone and gravel paving have been widely used, but this surface is replaced with concrete and asphalt which is laid on top of the compacted layer. You can now also get the best coloured road surfacing.

In this article, we will discuss the types of layering techniques and materials used.
Asphalt: – Asphalt, sometimes referred to as flexible pavement, has been one of the most popular types of construction since its introduction in the early 1920s. With this paving technique, a thick layer of asphalt is laid on an equally large gravel floor.
The advantage of this type of patch is that it makes a relatively small noise. It has a relatively low cost compared to other materials and is also easy to maintain and repair. However, asphalt has several drawbacks. It is significantly less durable and strong than other types of options.
Concrete: – Concrete is another desirable option for road surfaces, although it is mainly used for local roads and other types of construction. Concrete paving is made with a mixture of coarse aggregate, portland cement, sand and water.
There are different types of concrete road surfaces of CRCP, JPCP and JRCP. The only difference is the connection system, which prevents the formation of cracks. Concrete is more durable than asphalt but quite expensive to install and maintain.
Composite: – Composite pavement combines bitumen with a Portland cement concrete layer. This type of construction is mainly related to road recycling, maintenance and rehabilitation. An asphalt layer is placed over the damaged surface to restore a smooth wear surface.
