As plastic increasingly chokes the world’s landfills, and China announced last year it didn’t want to buy recycled plastic anymore, the what to do with it all has become a pressing question.

Why not recycle it and use it to build roads?

Bound together with plastic polymers, the asphalt will be cheaper and last longer than conventional pavement, according to independent experts.

One European firm already is combining plastic pellets with hot-mix asphalt to resurface roadways. A U.S. company says that once it finds financial backing, its product “could be deployed within six months” with a process that combines asphalt milled from the road’s surface with plastic urethane.

Creating New Uses For Excrement
A stretch of interstate highway near St. Louis, Missouri is now paved with asphalt made from pig manure:

“Whew!” gasped a worker with Pace Construction Co., the St. Louis County road contractor that joined forces with Innoventor, the Earth City-based engineering and design firm that perfected the process of converting the animal waste into a bio-oil used in asphalt binder.

To others, the air swelled with the sweet smell of potential for new manufacturing opportunities, jobs and, possibly, profits. How big is that potential? Nobody knows yet.

Varying mixtures of aggregate, sand and other binder materials used to create asphalt concrete samples

A great deal of effort is being invested towards discovering ways to make our world greener, with cars in particular being the focus of research and development initiatives. But what about the green credentials of the millions of miles of roads which carry our vehicles from A to B? This question is being addressed by researchers at the University of Wisconsin-Madison (UW-Madison) who are investigating ways to make asphalt environmentally friendly.
