A new type of asphalt de-ices itself during the winter, making road salt obsolete

With winter weather comes winter road salt. While snow and ice itself are gorgeous to look at, the ice-melting salt that comes with can be destructive to not only our cars, but our environment as well. Throughout the winter, salt must be reapplied to increase everyone’s safety, harming the environment in the process. But it looks like the frequent use of salt might change sometime soon.

A team of scientists at Turkey’s Koc University have created a new form of asphalt that can de-ice itself during the winter. This new asphalt mixture has combined the salt potassium formate with a hydrophobic (a.k.a water repelling) polymer, which is known as styrene-butadiene-styrene.

The team, which is led by Dr. Seda Kizilel, then mixed these chemicals with bitumen, the main binding ingredient in asphalt, creating a composite material that is just like regular bitumen with an added benefit—it significantly delays the formation of ice on its surface.

During the testing, this new material proved itself to melt ice for a period of two months. According to the study, the asphalt will last for much longer on the actual road.

This winter, I think I’ll take an order of asphalt, hold the road salt. Thanks.
