[Presentation of Materials] Can heat island effects be mitigated with heat-reflective pavement coatings?
Resin Pavement Association Certified Product "KE-283"
The color is the same, but the temperature is different. The heat-insulating paint cools the scorching pavement by 10°C.
A mechanism that can lower asphalt surface temperature by up to 10°C | What is the heat island countermeasure effect of heat-reflective paint? This product is a heat-reflective paint for road paving that comes in multiple colors such as black, ivory, and gray. While regular black paint can reach surface temperatures of around 100°C, heat-reflective black paint is able to keep it down to about 90°C. Ivory reduces the temperature from 75°C to 70°C, and gray from 81°C to 76°C, all of which have been proven in tests to lower surface temperatures compared to their regular color counterparts. It contains special components that reflect infrared rays, demonstrating heat-reflective performance without changing the visible color. Additionally, by scattering lime or ceramic aggregates on the paint surface, it is possible to further enhance the heat-reflective effect. It also excels in workability, allowing for application on existing asphalt surfaces.

Applications/Examples of results
It is suitable for application in places where surface temperatures tend to rise in summer, such as major roads and sidewalks in urban areas, and parking lots of public facilities. The rise in surface temperature is one of the main causes of the heat island phenomenon, directly linked to the increase in surrounding temperatures and the risk of heat-related illnesses for pedestrians and workers. By utilizing heat-reflective paint, it helps to reduce heat radiation from asphalt surfaces and contributes to the thermal improvement of urban environments. It can be used in a wide range of scenarios, including municipal environmental measures, the development of internal roads in factories and logistics facilities, and the improvement of sidewalks around schools and parks. Since it can be introduced with a similar construction flow to regular paint, it is attracting attention as a heat island countermeasure that minimizes additional costs to existing infrastructure.
