Seobuk District of Cheonan City Lowers Road Temperature with Asphalt Heat-Reflective Coating

Construction at the Entrance Intersection of Dujung-dong Food Alley

Seobuk-gu, Cheonan City, applied asphalt heat-reflective coating for the first time in the region to reduce road temperatures during the summer.

Seobuk-gu, Cheonan-si, Chungnam Province announced on the 27th that it has applied heat-resistant coating to asphalt roads in order to lower road surface temperatures during the summer.

According to Seobuk-gu, due to increasingly intense heat waves each year, asphalt surface temperatures rise above 70°C, causing not only asphalt deformation but also urban heat island effects that make various outdoor activities difficult.

The Construction Division of Seobuk-gu established an 'Asphalt Heat-Resistant Coating Construction Plan' and applied the coating to approximately 550 square meters at the entrance intersection of the Dujeong-dong food alley, the area with the highest foot traffic among the sections undergoing road maintenance on Dujeong-ro (from Prugio 5th Complex to Hyundai Motor Intersection).

This construction method uses special infrared-reflective silica sand and hollow silica sand to reduce the accumulation of solar radiant heat on the road during midday, thereby lowering the road surface temperature. It is expected to decrease plastic deformation of the road, suppress the heat emitted from the hot surface after sunset, and consequently mitigate the urban heat island effect.

District Chief Lee Jongtaek stated, "We will continuously measure road surface temperatures using thermal imaging cameras and monitor them in comparison with conventional asphalt pavement. If the effectiveness is confirmed, we will expand the application to major roads to provide a more pleasant road environment."
