Ministry of Land, Infrastructure and Transport Promotes 'Drainage Pavement' for Road Safety During Rainy Weather

[Asia Economy Reporter Yoo In-ho] The Ministry of Land, Infrastructure and Transport announced on the 9th that it will promote permeable pavement, which has superior drainage performance compared to conventional asphalt pavement.

Permeable pavement is a method that increases the void ratio inside the pavement from 4% to 20% compared to conventional asphalt pavement, allowing water on the pavement surface to drain through the pores. It also has the advantage of absorbing noise caused by tires, which is why it is called "low-noise pavement."

The Ministry plans to first apply permeable pavement to three noise-vulnerable sections of expressways and three ice-vulnerable sections of general national roads this year, and gradually expand its use.

Design standards for mixture design in expressway and construction specifications, which had been conservative in applying some permeable pavement methods such as new technologies and new construction methods, will be reasonably improved to enable the application of all permeable pavements on site.

Additionally, to clearly present the noise reduction effect of permeable pavement within this year, noise measurement standards will be established by adopting the internationally recognized standard (ISO 11819-2).

Kim Yong-seok, Director of the Road Bureau at the Ministry of Land, Infrastructure and Transport, said, "Permeable pavement has many advantages, such as preventing tire hydroplaning during rain, preventing road icing, thereby reducing traffic accidents, and also reducing road noise." He added, "If the plan to promote permeable pavement is established within this year, it is expected that public and client awareness of permeable pavement will improve from next year, leading to its activation."
