What are the quick repair methods we should use for potholes in city roads which is one of the main causes accidents?

Potholes in city roads are the main cause of accidents. These are left unattended for months causing accidents some time leading to fatality. What are the quick repair methods we should use for potholes in city roads which is one of the main causes of accidents?

Bitumen road is the most deceiving structure. It has a low initial cost, but the maintenance cost that follows is very high. Sometimes, these maintenance costs would override the costs of a concrete paver.

Potholes are not created overnight. It is a slow process. It occurs due to the water present below the soil, which forms holes below the pavement, due to the continuous flow of traffic, the pavement breaks. This situation is aggravated when the traffic flow continues. This movement will pump out the underlying soil and the bitumen outside, causing a hole.

The potholes can be repaired in two ways – Semi-permanent and Permanent.

Answering the question, The reason why the potholes keep occurring, again and again, is because of going for semi-permanent methods to repair them. Switching to permanent methods will solve the problem of accidents.

This includes cleaning the pothole thoroughly and removing the surrounding bitumen. Then another new layer of pavement is laid from scratch. This will prevent them from occurring again in the same place. Potholes can be avoided completely if the subsoil studies are intensified.

Asphalt Tile and Induction Heating :

One of the most advantageous methods of quick repair of road pavement is Asphalt tile and induction heating.

Brief introduction of Asphalt tile and induction heating technique for road repair :

  • In this system, Asphalt Tile is present which is composed of a bonding layer made up of polymer modified bitumen and steel fibres
  • The polymer-modified bitumen and steel fibres are heated using induction energy

How to apply Asphalt tile and induction technique :

  • Whenever a pothole appears, then clean up at the surface
  • Fill tile in that pothole, so that it is bonded to the old payment by means of induction in energy.

A speciality of asphalt tile and induction heating :

  • Asphalt tiles are used to fill potholes and bonded together using induction heating.
  • The shared strength of the bond is higher than the original material
  • The rutting resistance is 40 times higher than cold mix asphalt
