Soon we will see Auto / Self  Healing Roads 

Most of the times, there are small cracks occur in asphalt pavements. There are combination of factors leads to edge cracking. Although, engineers are finding various solution over it. For example, scientists are working on materials that repair themselves. They are mainly focusing on two of the most important materials in infrastructure: asphalt and concrete.

The largest use of asphalt is in road construction. It is easy to apply- just need to warm it, mix it and use it. Once it get cools, it becomes hard on road surface. By making use of it, developers at Delft University have developed a steel-infused asphalt to get rid of potholes, cracks and loose stones.

This steel-infused asphalt involves the use of steel wool to hold the tiny stones together.

Christopher Schlangen, a PhD student at Deflt University had shown that how cracks and potholes rejoin the asphalt after heating it into induction machine. But, he uses a microwave instead of induction machine and doubles the lifespan of it.

Schlangen said, “It has a multitude of positive consequences. Firstly, there are the economic impacts. Even the Dutch government could save 9 million by implementing his roads, despite the 25% more money they require to install.”

“Additionally, self-healing roads would mean fewer loose stones to flick up and chip windscreens, fewer potholes to damage axles or wheels, and fewer roads being closed for repair.”

Recently, developers at Delft University have developed a steel-infused asphalt that can be heated to get rid of potholes, cracks and loose stones, thereby saving millions on road repairs. The technology works by adding steel wool to bitumin, the binding agent that asphalt usually uses to hold the tiny stones together

Christopher Schlangen, a PhD student at Deflt University, has shown that if asphalt that contains these steel fibers is heated using an induction machine, the bitumin melts and therefore cracks and potholes rejoin. This could double their lifespan. Although he uses a microwave rather than an induction machine in the TED Talk below, its enough to show you the premise.

IN BRIEF

Christopher Schlangen at Deflt University has developed an altered form of asphalt that can be heated in order to heal cracks and holes. This has numerous benefits to individuals and governments.

The potential to heal roads has a multitude of positive consequences. Firstly, there are the economic impacts: Schlangen estimates that the Dutch government could save 9 million by implementing his roads, despite the 25% more money they require to install.

In addition to this, self-healing roads would mean fewer loose stones to flick up and chip windscreens, fewer potholes to damage axles or wheels, and fewer roads being closed for repair.

Although he is focusing on a means of perfecting his healing formula, Schlangen envisages a possible future use: charging cars at traffic lights. He said that “putting steel fibers in the asphalt means that you can send information to it, so it might be possible to charge electric cars on the road they’re driving on.”

These discoveries are similar to recent developments made in self-healing concrete by Cardiff University. Their project involves using bacteria to create self-healing concrete, according to the same principles as bone remineralization.

Now, he is focusing on to make his formula more efficient. According to him, it could be used in charging cars at traffic lights in future.
