Keeping drivers safe with a road that can melt snow, ice on its own

Slipping and sliding on snowy or icy roads is dangerous. Salt and sand help melt ice or provide traction, but excessive use is bad for the environment. And sometimes, a surprise storm can blow through before these materials can be applied. Now, researchers ave filled microcapsules with a chloride-free salt mixture that’s added into asphalt before roads are paved, providing long-term snow melting capabilities in a real-world test.Slipping and sliding on snowy or icy roads is dangerous.
