Take This Coffee for the Road

I have been hearing about Pavement Coffee in Boston from some of my students who reviewed Pavement for my coffee-shop assignment (yes, I'm that kind of professor). Meanwhile, my favorite librarian found a story that is literally about pavement coffee. (I'm also the kind of professor who grimaces when "literally" is misused; in this case, it literally is not.)
This shows coffee and pavement, but it is not clear whether it includes coffee pavement.
From the other side of the world comes news of materials scientists who have collected coffee grounds that would otherwise go to waste, and figured out a formula by which they could be repurposed to make underlayment for road surfaces -- the sub-pavement, as it were. The work was published in the forthcoming issue of Construction and Building Materials and is described by Phil Ritchie in Cosmos magazine.

We learned about it from Sarah McColl's article Where the Roads are Paved with Coffee, published in takeapart. Although the title suggests a bit more than the current reality, McColl's version of the story is a good read as she addresses other interesting aspects of coffee and coffee waste.
