High Friction Road Surfacing

Following recent research, it has been discovered that the average thinking time to brake and stop is double than that previously thought. Investigations, by the TRL, into the time it takes a driver to perceive, recognise and react to emergency situations found that the average thinking time is 1.7 seconds, this is more than double the 0.67 seconds set out in the Highway Code. Councils are now being urged to consider increasing their use of high friction road surfaces, providing a high level of skid resistance, enhancing safety, thus reducing accidents in high-risk sites.

Available as hot or cold applied systems, high friction surfacing (HFS) has a long history of proven use in saving lives by imparting the highest level of skid resistance onto a road surface. Cold applied systems comprise of a resin binder, which is applied by squeegee onto the road surface, this is then covered with a suitable aggregate. Once the system has cured any excess aggregate can be swept up and removed. The hot applied system involves the application of a hot thermoplastic binder combined with an aggregate which is then screeded onto the road in strips to cover the area required.

Calcined bauxite is an extremely hard, manufactured aggregate used in high friction surfacing. It has exceptional resistance to abrasion that is caused by vehicle tyres as well as a very high resistance to polishing. Because of this, the aggregate is able to retain its sharp edges which greatly enhances the skid resistance and service life.

Adbruf manufacture both hot and cold applied high friction surfacing materials, they have BBA and HAPAS certification, Type 1 classification and a hot applied HFS with Type 2 classification.
