Kumipäällysteellä

Kumipäällysteellä is a Finnish term that translates to "rubberized pavement" or "rubber asphalt" in English. It refers to a type of asphalt mixture that incorporates recycled rubber, typically from old tires, into the bitumen binder. This modification aims to enhance the performance characteristics of traditional asphalt.

The process involves grinding scrap tires into fine rubber granules, which are then blended with hot mix asphalt. The addition of rubber can lead to several improvements. For instance, it can increase the elasticity and flexibility of the pavement, making it more resistant to cracking caused by temperature fluctuations and heavy traffic loads. This increased durability can potentially extend the lifespan of roads.

Furthermore, rubberized asphalt may offer benefits such as reduced noise pollution. The rubber particles can absorb some of the sound generated by tire-road interaction, leading to a quieter driving experience. It also provides an environmentally friendly solution for disposing of a significant amount of waste rubber, diverting it from landfills. The use of kumipäällysteellä is a growing trend in road construction, driven by its performance advantages and sustainability aspects.
