Kalvopäällyste

Kalvopäällyste is a type of road surface treatment that involves applying a layer of oil-based emulsion to pavement. The treatment is commonly used in countries with cold climates, particularly in Finland and other Northern European nations.

The emulsion is typically composed of oil, water, and additive materials. It is applied to the pavement in a thin layer using specialized equipment. The treatment is designed to help the asphalt pavement to survive harsh winter conditions by protecting it from damage caused by freezing temperatures and thawing.

When the emulsion is applied, it forms a thin film that prevents moisture from penetrating the pavement. This helps to prevent the formation of ice and the resulting damage that can occur when water seeps into the pavement and freezes.

The benefits of kalvopäällyste include improved road safety, as it helps to prevent slippery road conditions during the winter months. It also extends the lifespan of the pavement by protecting it from wear and tear caused by the freeze-thaw cycle.

In addition to its safety benefits, kalvopäällyste is also considered a sustainable road maintenance option. It is a low-maintenance treatment that can reduce the need for more expensive and invasive repairs.

Overall, kalvopäällyste is a common road surface treatment in regions with cold winters, and is widely used by road maintenance authorities and contractors. Its benefits include improved road safety, extended pavement lifespan, and sustainability.
