Road Surfacing

Have you ever suffered from the experience of driving your vehicle on a road full of potholes? It seems as if every bone in your body will break apart whenever the tyres of your vehicle lands on a pothole. The surface of roads suffers from damages whenever rainwater inundates them and leaves them covered with water for prolonged periods. This problem remains until the municipal corporation fills up the potholes and resurfaces the road.

What is used to surface roads?

The staffs of the municipal corporation employ bituminous surface treatment, also known as chipseal, to surface roads. In this process, the personnel entrusted with the task heats asphalt along with other materials in an industrial powder blender. However, the process has changed quite a lot over the years and nowadays asphalt emulsions are the preferred choice of resurfacing roads. They consist of a mixture of special oil suspended on water. A tanker containing the mixture sprays the surface of the road with this mixture through a spray bar that permits even distribution of the asphalt emulsion on the road. The material appears to be brownish during the spraying process. However, its colour changes to black after some time.

Why are these materials used?

These materials are used as they withstand the changes in temperature much more than bitumen. On a typical basis, a resurfaced road lasts for several years before its surface starts deteriorating, following which the process has to be done again. These materials also prevent the car from skidding when brakes are applied on a surface damped due to rainfall. They also shine less than the materials used in chipseal. This prevents headlights of cars from reflecting from the surface of the road and temporarily blinding the eyes of drivers approaching from the other side. The surface should be such that provide adequate grip to the tyres of the vehicle while it is moving, and allowing it to grip the surface when the driver applies the brakes.

Why do roads need resurfacing?

The surface of roads has to bear the weight of heavy vehicles passing over them. Each time the driver of any vehicle applies the brake, a tiny portion of the surface coating gets damaged due to friction. Over a period the surface gets damaged to such an extent that the subsoil gets exposed, leading to breakage and the formation of potholes. If proper care is not taken in time, the size of the potholes increases, posing dangers to motorists. In addition, water accumulating on the subsoil spreads to nearby areas and damages their surface too. This is the primary cause why roads need resurfacing.

Who resurfaces roads?

Professionals of the municipal corporation are entrusted with the task of carrying out such a procedure. They have the materials and the equipment required, such as the industrial powder blender needed to complete the procedure.

When are roads resurfaced?

As excessive water and cold hampers the resurfacing process, this personnel of the municipal corporation carry out this procedure during the summer season.
