Anti-Skid Surfacing FAQs: Your Guide to Anti-Skid Surfacing
Anti-skid surfacing is used for car parks, junctions, pedestrian crossings and other high-risk areas where increased surface friction and enhanced grip is important. In this article, we’ll be covering some popular anti-skid surfacing FAQs so you can get clued up on this essential road safety surfacing – including what it is, how to use it and how to apply it.
The Top Anti-Skid Surfacing FAQs
What is anti-skid surfacing?
Anti-skid surfacing is a type of surfacing material that is applied to areas that require high skid resistance. Also known as high-friction surfacing, it is mainly used for areas where safety needs to be enhanced to prevent collisions, such as car parks and junctions. Instead of a smooth and slippery surface, anti-skid surfacing provides a surface with much greater friction when compared to asphalt, which reduces stopping distance and improves grip.
How does anti-skid surfacing work?
Anti-skid surfacing is made from an aggregate called calcined bauxite, which is resistant to polishing and also has impressive anti-abrasive properties. When laid, the surface has many contact points which are formed by using a binder with the calcined bauxite. This results in a textured surface with a high degree of friction and improved grip. Anti-skid surfacing also tends to last a long time without getting worn down by frequent road use.
Where should anti-skid surfacing be used?
Due to its ability to increase road friction and safety, this surfacing choice is used for areas where the risk of road accidents and collisions is higher. These areas may include:
- Car parks
- Pedestrian crossings
- Bus lanes
- Cycle lanes
- Sharp bends
- Pedestrian pathways
- Coloured parking bays
What’s the difference between hot and cold anti-skid applications?
When researching anti-skid surfacing, you will discover there are two ways to apply the surfacing, either hot or cold. So what’s the difference?
- Hot application: The calcined bauxite aggregate is mixed with a bonding agent (usually thermoplastic binder) at a high temperature. A screed box then applies this mixture to ensure perfect coverage and texture.
- Cold application: The road surface is covered with a binder and then the calcined bauxite aggregate is applied on top afterwards. The final result of the cold-applied technique tends to be slightly more durable and long-lasting than the hot-applied method.
What are the benefits of anti-skid surfacing?
Anti-skid surfacing has many advantages over traditional asphalt surfacing, including:
- Application is relatively quick so there is minimal disruption to traffic during the laying process
- Safety is enhanced, grip is improved and stopping distance is reduced, which helps to reduce the likelihood of collisions and other accidents
- Because the surfacing is resistant to polishing and abrasion, it lasts for a long time without needing to be replaced – much longer than standard asphalt
- It can be applied to any type or class of road, ranging from small cycle paths to major motorways, just so long as the road is in a decent condition to begin with
What’s the difference between anti-skid and high-friction surfacing?
There is actually no difference between anti-skid surfacing and high-friction surfacing (sometimes abbreviated as HFS). They are simply different terms which refer to the same type of surfacing.
How do I apply anti-skid surfacing?
To ensure legally-compliant and safe application of anti-skid surfacing, make sure that it is laid by an experienced specialist.
