Researchers in Turkey have developed a new road surface that delays the formation of ice.
Academics at Koç University College of Engineering in Istanbul carried out research to try and break the cycle of roads constantly having to be de-iced.
Led by associate professor Seda Kizilel, they combined salt potassium formate and polymer styrene-butadiene-styrene. They added this mixture to bitumen, a major component of asphalt.
They found that the final material was just as strong as unmodified bitumen, however in the lab studies it significantly delayed the formation of ice formation.
In the lab the material released de-icing salt for two months. According to the researchers, it means there’s the potential for salt to be released over years as vehicles wear away the road surface.
