The future of pothole repair is Silly Putty

Pot holes pepper highways everywhere.

Fixing a hole in a road should be easy—but the fact that our nation’s highways are littered with potholes is testament to the fact that it’s not quite as straightforward as it sounds. But a new solution, inspired by silly putty, could make our streets much smoother in the future.

In fact, the idea—developed by students from Case Western Reserve University in Cleveland—has won an engineering contest, reports Science. But prize-winning or not, the idea of mending a road with something like silly putty sounds like madness, right?

Mountains of salt are spread on snowy roads in North America every winter, and environmentalists have been complaining about it for years. But studies are piling up that indicate that the cost may be too high.

Martin Mittelstaedt reports in the Globe and Mail about a new study of Frenchman’s Bay, a lagoon off Lake Ontario by University of Toronto Geologists. The conclusion:

“Our findings are pretty dramatic, and the effects are felt year-round,” said Nick Eyles, a geology professor at the university and the lead researcher on the project. “We now know that 3,600 tonnes of road salt end up in that small lagoon every winter from direct runoff in creeks and effectively poison it for the rest of the year.”
