Use of nanotechnology in road construction?

As you can guess, I'm getting very curious about the road construction technology. I stumbled upon an old article that talked about usage of "Zycosoil" Nano-Technology in road construction. The technology is said to cut down on the overall cost of construction and drastically improve the load bearing capacity of the road. An Indian company holds a patent to this technology.

The technology eliminates the need of laying a stone layer while constructing the load and this makes the road very cost effective. Would love to hear more thoughts on this.
