Nanotech Hits the Roads
When you hear the word 'nanotechnology,' I bet you immediately think about nanochips or ultra-small medical devices. But do you know that nanotechnology is starting to be used in highways, bridges and other buildings? In "Small Science Will Bring Big Changes To Roads," a very long article from Better Roads Magazine, you'll discover that "research in structural polymers could lead the way to guardrails that heal themselves, or concrete or asphalt that heal their own cracking." Nanotechnology is also used to design better steel or concrete.

And there are even nanosensors in place on the Golden Gate Bridge to monitor its behavior. The nanotechnology revolution is on its way in the construction business, even if self-healing potholes and guardrails are still science fiction. This long article discusses nanotechnology advances in concrete and cement, self-cleaning traffic signs or better steel. This shorter overview contains selected excerpts about embedded nanosensors, self-healing pavements and smart dust.
