Winter weather poses significant challenges for road maintenance, with snow and ice accumulation causing hazards and necessitating costly clearing operations. However, researchers at Drexel University have developed a groundbreaking solution: self-heating concrete integrated with a phase-change material. This innovation promises to melt snow and ice for extended periods without the need for salt or manual intervention, offering a sustainable and efficient alternative for road management.
The integration of a phase-change material, specifically paraffin, into concrete slabs enables them to release heat when temperatures drop, effectively melting snow and ice. By maintaining a surface temperature above freezing, the self-heating concrete reduces the need for plowing and salting, mitigating the associated costs and environmental impacts.
