234. 凍結防止剤（塩）
塩は、冬季の道路で凍結防止・融氷のため一般的に使われます。水の凍結温度を下げ、氷の形成を防ぐ、または既存の雪や氷を溶かすのに役立ちます。道路管理者は乾燥塩、湿塩、塩水などを凍結前や凍結中に散布します。塩で安全性は向上しますが、大雪、着氷性の雨、極低温では処理済み道路でも危険なため、速度を下げ状況へ適応します。
Is salt used to treat roads in Belgium?
Yes. Belgian road authorities use salt, wet salt and brine to help prevent or remove snow and ice during winter conditions.
Are Belgian roads salted before ice forms?
Yes. Road authorities can carry out preventive salting before frost, ice, snow or freezing rain develops. This is known as anti-icing and can reduce the risk of slippery roads.
Who is responsible for salting roads in Belgium?
Responsibility depends on the road. Regional authorities maintain motorways and regional roads, while municipalities are generally responsible for local roads under their control.
Does salting mean a Belgian road is no longer slippery?
No. Even after treatment, roads can remain slippery during snowfall, freezing rain, frost or rapidly changing temperatures. Drivers must still adapt their speed and following distance to the actual conditions.
Does Belgium use preventive salting?
Yes. In Flanders and Wallonia, winter services use preventive treatments based on weather forecasts and road-condition monitoring to reduce the risk of frost and ice forming.
When does the winter road service operate in Belgium?
The exact organisation differs by region. In Flanders, the winter service normally runs from the third Monday of October until the fourth Monday of April. In Wallonia, the regional winter service normally runs from 15 October to 15 April.
