#ARCTIC. #SIBERIA. THIS IS TAIMYR. Russian scientists have developed a frost-resistant biopolymer material to improve the strength of roads in the Arctic, reports Georgy Lazarenko, head of the closed-loop technology competence center of the Advanced Engineering School of Novosibirsk State University (NSU).
As the developer noted, temperature changes often cause the soil surface degradation, which creates risks for the infrastructure being built on the soil.
“We use biopolymers that form a structure as a result of temperature changes and the freeze-thaw cycle. It is created in such a way that the strength of the material increases with each cycle”, Lazarenko said.
The NSU Advanced Engineering School’s press service clarified that this is a mixture of different biopolymers. The exact component composition of the material is a commercial secret. Lazarenko emphasized that the materials can be used in road construction to strengthen the soil foundations of roads, both automobile and railway. The developed components meet high environmental requirements and standards for the Arctic regions, TASS writes.
Laboratory tests show that the resulting material can withstand temperatures down to minus 20 degrees Celsius. Industrial testing of the technology is planned to begin next year, the scientist specified.
