De-icing pavement

Pavement heating system

Icy conditions are a pressing issue for northern cities. Traditional methods, such as salt and chemical reagents, may be harmful to citizens, urban infrastructure, and the environment. Therefore, cities explore alternative methods for deicing roads.
Countries using the system:
Страна
Holland (USA)
Страна
Montreal
(Canada)
Страна
Oslo (Norway)
Страна
Helsinki
(Finland)
In Holland, such systems heat the roads with circulating hot water heated by residual heat from electricity generation.
Main characteristics of the system
Project Length: 8 km
Heating Season: 3 months
Project Cost: ~2 million USD (50% - municipal funds,
50% - commercial property owners covered by the system)
Maintenance Cost: 135
thousand USD per year
In Oslo, electric heating elements are activated by special sensors.
In Helsinki, sidewalks are heated using both electric heaters and circulating hot water from district heating plants.
Due to high costs, systems are installed by city authorities selectively on central streets to stimulate business activity or on private properties.

International cases of using
anti-icing asphalt

Countries using
anti-icing asphalt:
Страна
South Korea
Страна
Italy
Using asphalt produced with special anti-icing additives helps prevent ice formation on roads.
Pilot projects were implemented in Italy (2010) and South Korea (2019). In South Korea, the Russian-made "Grykol" asphalt additive was used, produced from chloride salts and hydrophobizer.
