Colored surfaces alert drivers that they are entering a high-risk or otherwise significant section of the road. The color itself does not increase surface safety. For vehicle handling, skid resistance—the ability to ensure sufficient friction between the tire and the road—is also essential.
That is precisely why safety surfaces use special mineral aggregates. One of these is bauxite aggregate, which, thanks to its hardness and resistance to wear, helps create and maintain a rough surface texture over the long term.
The anti-skid properties of a road affect, for example, braking, vehicle handling in curves, or vehicle behavior on wet roads. Surface texture, which consists of microtexture and macrotexture, plays an important role in this.
Simply put: the tire needs to have sufficient contact and friction with the surface. If the surface is too smooth or its structure gradually becomes "polished" by traffic, its anti-skid properties can deteriorate.
That is why, for safety anti-skid surfaces , it is important to monitor not only their initial roughness but also how well they maintain it over time.
Bauxite is a very hard mineral material that is resistant to wear and polishing. This is precisely why it is used as an abrasive material in anti-skid road surfacing.
In WeTraffic systems, bauxite filler is incorporated into the PMMA binder. This creates a surface structure that enhances anti-skid properties and is designed for long-term mechanical stress.
This is particularly important in areas subject to frequent braking, changes in direction, or high traffic loads.
A safety surface must perform well beyond just the first day after application. Tires, water, winter maintenance, and other factors gradually take their toll on the surface.
With standard materials, the aggregate can gradually polish, leading to a change in anti-skid properties. The resistance of aggregate to polishing is therefore a key parameter when evaluating the long-term anti-skid performance of road surfaces.
The high hardness of bauxite helps mitigate this issue. As a result, the surface can maintain its required structure over the long term, even under heavy traffic.
High skid resistance is crucial primarily in areas where there may be a need for heavy braking or rapid changes in direction. Typical examples include:
These are the exact locations where anti-skid safety treatmentsare used, aiming to improve traffic safety through enhanced surface properties.
Color and anti-skid properties address two different needs.
Color helps visually highlight an area and guide drivers, pedestrians, or cyclists. Bauxite aggregate helps create a rough and durable surface texture, which is essential for anti-skid performance.
For modern safety surfaces, it is therefore not just about the road looking good. It is important that it also has appropriate functional properties and can maintain them over the long term.
WeTraffic systems combine color finishes with mineral bauxite aggregate for this very purpose. The result is a surface suitable for locations where, in addition to visual highlighting, high skid resistance and mechanical durability are also important.
Bauxite filler is a mineral material with high hardness and wear resistance. In anti-skid surfaces, it is primarily used to create a durable and textured surface structure.
Its high hardness and resistance to polishing help maintain the surface's anti-skid properties even under long-term traffic loads.
Bauxite filler contributes to the anti-skid properties of a surface. These are one of the factors affecting traffic safety, especially when braking and cornering. However, overall safety also depends on other road characteristics, the vehicle, and traffic conditions.
No. Color is primarily used for visual highlighting and orientation. Anti-skid properties are determined mainly by the structure and material composition of the surface.
