Just as winter is nearing, scientists made a discovery that will improve driving conditions in winters to come. The research team at Drexel University found that by adding paraffin wax to concrete roads, the concrete melts snow all on its own.
The United States uses roughly 17-20 million tons of road salt each year according to the Salt Institute of the United States. We do this to keep roadways open and safe to snow and ice. The combination of salting and plowing roads causes deterioration of roads and introduces massive amounts of salt into urban environments.
