Purdue University researchers have developed the world's whitest paint, with an albedo of .981. They say it could eliminate the need for air conditioning (and drive up the neat for heating). This would greatly reduce the amount of softening of asphalt that leads to rutting.

The polar opposite of Vantablack.

They should spray that stuff on Alaska's highways

Researchers at Worcester Polytechnic in Massachusetts have found that by adding an enzyme found in human blood they can make concrete that will heal any cracks automatically within 24 hours. The enzyme reacts with carbon dioxide in the air to form calcium carbonate.

They say that this would increase the cost of concrete by a small amount while quadrupling its durability. This is a big deal for highway and bridge engineering. And it's a reminder that plenty of innovation in Massachusetts can come from outside 495.

The guy who discovered it, Nima Rahbar, told me in an email that he founded a company, Enzymatic, to commercialize it.

We really need self healing, ultra high performance fiber reinforced concrete.

Imagine if you could build bridges without any rebar that would last for centuries.

Is there a word for “gadgetbahn”, except it’s for roads? I think that word would apply to most things in this thread.

My Fictional Highways

Fundamental Theorem of AARoads - Let "y" represent the elevation above sea level in a certain area. If "Δy" between the highest and lowest values of y equals to 0, it's Illinois.

And just like the streetcar fanatics who coined that phrase, you are making the questionable assumption that today's solutions are satisfying.
