Rullebelægning

Rullebelægning, often referred to as roll-on surfacing or rolled asphalt, is a method of applying asphalt for roads and other paved surfaces. It involves using a specialized asphalt mixture designed for a lower temperature application compared to traditional hot-mix asphalt. This mixture is transported to the site in insulated trucks and then laid using a paving machine that can effectively spread and compact the material at the required temperature.

The process typically begins with the preparation of the existing surface, which may involve cleaning, patching, or applying a tack coat. The rullebelægning mixture is then discharged from the truck into the paver's hopper. The paver then spreads the asphalt evenly across the surface to the desired thickness. Compaction is achieved through a combination of the paver's screed and subsequent rolling by a vibratory roller. The lower application temperature allows for faster cooling and opening of the road to traffic, which can be a significant advantage in busy urban areas or during time-sensitive construction projects.

Rullebelægning is suitable for a variety of applications including new road construction, resurfacing existing roads, and creating pathways or parking areas. It can offer environmental benefits due to reduced energy consumption during production and a lower emission profile compared to traditional asphalt. However, the specific mix design and application techniques are crucial for ensuring durability and performance.
