Research and Exploration of Phase Change Materials on Solar Pavement and Asphalt Pavement: A review

摘要

The consumption of non-renewable resources has made the earth's resource crisis increasingly prominent. Renewable energy solar energy is more and more popular. Highways occupy a large proportion of the surface area and therefore become an excellent carrier for the development and utilization of solar energy. Solar pavement and asphalt pavement are the two most common ways to use solar energy. Phase change material (PCM) uses its own latent heat to enable asphalt to absorb or release a large amount of heat under constant conditions to regulate the road surface temperature. Based on these issues, this paper compares the development of solar pavement and asphalt pavement. It also introduces the principles of solar power generation and examples of heat utilization. The research methods of using phase-change materials to modify the temperature of solar pavement and asphalt pavement are reviewed. It summarizes the progress of materials in pavement application and prospects the future development trend of solar pavement.
