Different methods of road construction in civil engineering

1) Concrete: 

It is a common option for road construction purposes as they are a solid material and can be used for building walls and local roads. This method is considerably less prone to wear and tear defects like rutting, cracking, stripping loss of texture, and potholes. This is the main reason for its wide usage.

2) Asphalt: 

This method of construction replacing concrete method in these days. They are very durable, water-resistant and can go more longer then the concrete. The major advantage of asphalt over concrete is its price. Concrete is very expensive as compared to asphalt. Moreover, asphalt includes low noise during pavement and it is easy to handle it for repairing and maintenance. That is why it is widely accepted and used by the people for the purpose of pavement surfacing.

3) Composite: 

This method is widely used for the maintenance, recycling, and rehabilitation of the roads. The composite material is the combination of both asphalt and concrete material.

4) Bituminous: 

The solvent from the bituminous material will evaporate and the bitumen will bind the aggregate. It is used in road construction because it is easy to produce, reusable, non-toxic, and a strong binder.

5) Recycling: 

Recycling or repairing of a damaged road surface consists of three different types of construction methods:

(a)Full depth replacement

(b)Hot or cold prepared road recycling

(c)Rubberizing

These are the different types of road construction.
