SEOUL, Mar. 12 (Korea Bizwire) — The Seoul Metropolitan Government plans to make use of eco-friendly pavement that will be able to absorb fine dust.
The city announced on Monday that it has come up with a comprehensive plan for eco-friendly pavement that will include warm-mix asphalt pavement and other solutions to catch fine dust.
Eco-friendly pavement also includes noise-reducing pavement and pavement that uses new or recycled materials.
As for dust reduction pavement, warm-mix pavement is the most commonly used method, while a photocatalyst coating for pavement and room temperature pavement are currently being developed.
Warm-mix pavement involves reducing the temperature needed to pave roads by 30°C compared to normal to reduce the amount of nitrogen oxide and other kinds of contaminants caused by the heat during road construction.
Seoul plans to gradually expand warm-mix pavement throughout the city, and make use of the surfacing technique for all future maintenance work on roads starting in 2027 to reduce fine dust.
Photocatalyst-coated pavement absorbs and dissolves nitrogen oxide found in car emissions.
The city tested photocatalyst coating on roads near Yangjae Station last year, and plans to carry out various road projects not only to cut down fine dust, but also reduce noise, as well as the heat island effect in the city.
