Potholes are aggravating to drive over, and they can cause billions of dollars of damage every year to automobile wheels, tires and suspensions. Currently, road crews fill in these holes with hydrocarbon-containing asphalt, but that material can leach out, polluting the environment. Now, scientists report a brand-new way to repair roads that's also eco-friendly—by using a remnant of wastewater treatment called grit that's usually disposed of in landfills.
